1. In Notepad, open the file Extension_xxx_user.cfg in the folder C:\AltiServ\PolycomCfg, where xxx is the 
extension number. 
2. Insert  between the xml tag  and .   
x = the number of columns you want to appear; enter a value from 1-4 
3. Save the file. Reboot the phone. 
Here are the maximum number of columns that you can display: 
 VVX 500: 3 columns (if you specify 4, only 3 will appear) 
 VVX 600: 4 columns 
 
Polycom-to-Polycom Video Support 
In this release, MaxCS supports video calls on Polycom IP phones for Softswitch deployments. Video calls are not 
supported on Max1000 or Office systems. 
Supported devices include: 
• VVX500 and VVX600 (these models require a separate Polycom VVX USB camera) 
• VVX1500 (this model has a built-in camera) 
Considerations: 
 Video conferences are not supported; only direct peer-to-peer calls are supported. 
To configure support for video calls, 
1. In MaxCS Administrator, open Boards View, double-click the HMCP board, and click Board Configuration. 
2. In the Video Forwarding Resource section, assign a number of resources for video.  
 
Figure 44: The field to specify the number of resources to dedicate to video 
You must assign sufficient video forwarding resources.  Be aware that the larger the number that you 
assign, the more overhead you will impose on your system.

3. Open Enterprise Manager.  For the profile that the Polycom phones use, check the Enable H264 Codec 
option.  Note that MaxCS does not support video over SIP Tie trunks or SIP Trunks. 
In order to support video calls between VVX phones at multiple sites, the ‘Default’ codec must have the 
Enable H264 option checked. 
 
Figure 45: The option to enable video codec (in Enterprise Manager) 
4. Close Enterprise Manager. In MaxCS Administrator, select PBX > AltiGen IP Phone Configuration. For each 
Polycom extension that will have video enabled, make sure that the option Enable Polycom Advanced 
Features is checked (on the General tab). 
 
Figure 46: Enable the Advanced Features option 
5. Switch to the Polycom tab in that window. For each Polycom extension that will have video enabled, 
check the option Enable H264 Video and set a maximum bitrate for Polycom phones; the default is 768 
kbps.  Set DSCP for video to AF41

6. If SRTP and TLS are enabled on these phones, select PBX > Extension Configuration.  For each Polycom 
extension that will have video enabled, check the option Connect Media Stream to Server on the General 
tab. (This requirement may be not be needed in future Polycom releases.)

7. Reboot the phones.  
8. Make a direct call between two of the video-enabled Polycom phones and test that the video appears on 
both phones. 
Operational Notes 
 If two Polycom phones are on a video call, and one phone conferences in a third participant, video will be 
lost.  Video will not return even when the third participant drops out of the conference. 
 When a Polycom phone transfers a video call to another party, the video will freeze for the user making 
the transfer.  The user can click Stop/Start to resume the video. 
Using an FTP Server to Update Firmware Files 
For some organizations, extensions do not have access to the internet, which can make it difficult to update 
firmware on Polycom phones.  For these situations, you can use an FTP server to update the firmware. 
In these instructions, the open-source FTP server FileZilla is used to demonstrate how to update firmware files to a 
Polycom IP phone. If you are using a different FTP server, the configuration procedure will be similar.  This FTP 
server and Polycom phones to be upgraded should be on an isolated LAN, to minimize any potential problems that 
may arise. 
For a Private Cloud or On-Premise configuration, consider installing the FTP server on the MAXCS server. Port 
forwarding for FTP is required if the MAXCS server is behind NAT.  
Note:  We recommend that you use these procedures only in environments where you cannot follow the 
procedures described earlier in this manual.  
Set up the FTP Server 
Note: Stop other FTP servers while using FileZilla as an upgrade server for Polycom IP phones.  
1. Download FileZilla FTP Server from http://filezilla-project.org/download.php?type=server.  
2. Set up the FTP user and home directory: 
A. Start FileZilla Server from the Start menu and connect to the server. (The Administration password 
field is blank by default.)

Figure 49: Set up the FTP Server 
B. From the Edit menu, select Users.  
C. In the General page, enter a username and password.  The Polycom factory default values are user 
“PlcmSp=p” and password “PlcmSp=p” - the password is case-sensitive.    
Note that you can use a different username and password – they must match the user name and 
password that you enter in the Provisioning Server page of the Polycom phone tool in step 3 on page 
45. 
 
Figure 50: Enter a username and password 
D. Click the Shared folders page and add the directory that you want to use as the FTP root (for ex-
ample “C:\FtpRoot”), and then click the Set as home dir button to make it the home directory.  
E. Check all of the privileges in the Files and the Directories sections and click OK.

Update Firmware and the Default Configuration Files  
For SoundPoint phones, in order to update the firmware from the Software Update page, a version 
5.x.x.x Updater (BootROM) is required. Please refer to the “Polycom Release Matrix” at this URL:  
http://downloads.polycom.com/voice/voip/sip_sw_releases_matrix.html 
Use one of these sites to upgrade:  
http://support.polycom.com/PolycomService/support/us/support/eula/ucs/UCagreement_5_2_2_split.html 
 
Store the firmware file ‘Polycom_UC_Software_5_2_2_release_sig_split.zip in the FTP root, and store the unzipped 
files under the FTP root (use the folder that you specified on page 44. 
1. On the VVX or SoundPoint phone’s menu, under Settings > Status > Network > TCP/IP Parameters, 
determine the IP address of the phone. In this example, the address is 192.168.1.76.  
2. Open a web browser to visit the =P phone’s configuration page (in our example, this URL is 
http://192.168.1.76. Log into the web interface (as admin) and enter 456 as the password.  
3. Select Settings > Provisioning Server 
 Set the Server type to FTP 
 Set the Server Address to the IP address that the Filezilla application is running on 
 Set the Server User to the username that you added in Filezilla (from step C on page 44) 
 Set the Server Password to the password that you applied in Filezilla (from step C on page 44) 
4. Expand the DHCP Menu section at the bottom of the window. Ensure that the Boot Server dropdown is 
set to Static.

5. Click the Save button at the bottom of the screen. 
6. Click Yes when you are prompted “Do you want to save the configuration changes?  The phone should 
now reboot. 
7. Monitor the Filezilla window for login and updates.  If the login is successful, there will be multiple 
iterations of information provided in the upgrade window.  One of which should name the 3111-xxxxx-
002 file, or similar.  This is a good indication that the phone is being upgraded. 
Note:  The upgrade process takes several minutes.  In one test scenario, ten minutes elapsed before the process 
was completed.   
Once you are able to log back into the phone, you may need to retrieve the configuration file from the server once 
again.  You do so by following these steps: 
1. Open a web browser to visit the =P phone’s configuration page (in our example, this URL is 
http://192.168.1.76. Log into the web interface (as admin) and enter 456 as the password.  
2. Select Settings > Provisioning Server 
 Set the Server type to HTTPS. 
 Set the Server Address to the IP address of the ACM server.   
						

							 
Polycom Configuration Guide   Page 47 of 52 
 Set the Server User to the extension user name. 
 Set the Server Password to the extension password. 
3. Expand the DHCP Menu section at the bottom of the window. 
 Ensure that the Boot Server dropdown is set to Static. 
 
Figure 53: Server Type HTTPS - Set Boot Server to Static 
4. Click the Save button at the bottom of the screen. 
5. Click Yes when you are prompted “Do you want to save the configuration changes?  The phone should 
now reboot. 
Self-Signed Polycom Phones 
As mentioned earlier, some Polycom phones, including, but not limited to, those that were manufactured in or 
prior to 2009, may be self-signed phones that do not have a factory-installed certificate. These phones are not 
recommended for use with MAXCS Release 8.0.   
						

							 
Polycom Configuration Guide   Page 48 of 52 
To determine whether a phone is a self-signed phone, in the phone’s menus select Settings > Status > Platform > 
Phone. Press the down arrow key to scroll to view the device certificate.  =f the setting is “Self-Signed” instead of 
“Factory =nstalled,” then we do not recommend the phone for use with MAXCS 8.0. 
If you want to try to use a self-signed phone with Release 8.0, which is not recommended, you will need to 
perform additional steps: 
1. In the web configuration utility, select Settings > Provisioning Server. Set Tag SN to UA to Enable. 
2. Perform the steps in this guide to set up the phone. 
3. On the MAXCS server, run the registry editor (regedit) with Administrative rights to locate the setting for 
the phone’s MAC address (remember to follow all Microsoft guidelines when editing the registry): 
64-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\AltiGen Communications, 
Inc.\AltiWare\PolycomPhoneServ\PhoneList 
 32-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\AltiGen Communications, 
Inc.\AltiWare\PolycomPhoneServ\PhoneList 
4. Change this value (PhoneList) from 0 to 1. This change will allow MAXCS to try to accept the Polycom 
phone with the MAC address. Save the changes. 
5. Reboot the phone; it should work correctly. 
Customize the Digit Map 
In most cases, you can automatically generate a Polycom digit map that matches your system. However, if your 
extension length, trunk access codes, or any other settings do not match the defaults, then refer to the next table 
to see which entries you need to change.  
 
 
Following is an example of a digit map: 
0 | # # | # [ 1-3 ] x | # [ 5-9 ] x | # 4 1 x x | # 4 [ 2-9 ] | [ 1-7 ] x x | 9 , [ 2-9 ] x x x x x x | 9 , 1 x x x x x x x x x x | 9 , 1 1 | R R 9 1 R [ 2-
9 ] x x x x x x x x x T | x x x . T 
Parameter Description 
0  The user can dial 0 to ring the operator extension or WG defined in the AltiGen server 
##  Accept ## to access voice mail 
Figure 54: Example of Polycom Phone Digit Map   
						

							 
Polycom Configuration Guide   Page 49 of 52 
Parameter Description 
#[1-3]x  Accept feature code #1x, #2x, and #3x 
#[5-9]x  Accept feature code #5x, #6x, #7x, #8x, and #9x 
#41xx Accept system call park with two-digit ID 
#4[2-9]  Accept other feature codes starting with #4  
[1-7]xx  The extension length is three digits with a prefix starting with 1 to 7 (for example, 
extension 123 is a valid extension number, but 823 or 923 are not); if your extension digit 
length is 4, then change [1-7]xx to [1-7]xxx 
9,[2-9]xxxxxx  The dialing trunk access code is 9 plus a 7-digit local call; if your local call is 10-digit 
dialing, change this to 9,[2-9]xxxxxxxxx. The comma (,) provides a second dial tone when 
the caller presses 9. 
9,1xxxxxxxxxx  The dialing trunk access code is 9 plus an 11-digit long distance number; the comma (,) 
provides a second dial tone when the caller presses 9 
9,11  Force a call to be sent immediately if 911 is dialed 
RR91R[2-9]xxxxxxxxxT   For 10-digit dialing, insert 91 as the prefix. For example, suppose a user dials 4085979000 
on a Polycom phone.  The Polycom phone will send 914085979000 to MaxCS instead of 
4085979000. 
xxx.T  Force a call to be sent immediately if 3 or more digits are dialed and the “dial” softkey is 
pressed; this sets the minimum digit length before the dial softkey will appear. 
Note:  If a dialed number is not defined in this dial plan, the caller will need to either wait for the call to time out 
or press the softkey Send to initiate dialing. 
Operational Notes 
This section describes various feature implementations with Polycom phones. Remember that Polycom phones will 
behave slightly differently from AltiGen IP phones. 
General 
 Some Polycom models may respond to user input a bit slowly. Please give the phone time to process 
the digits you have entered. 
 If you use IP address as a certificate, then later change it to an FQDN, you will need to re-enable the 
Record feature and the Directory feature for extensions. They will not work if you do not re-enable 
these two features. 
 If your environment includes both AltiGen IP phones and Polycom phones, be aware that Polycom 
phones support G.722 codec, but the AltiGen IP-705, IP-710, and IP-720 phones do not support it. 
(The AltiGen IP-805 phone does support the G.722 codec.) 
 If you use the web configuration tool to change the server password, after the phone reboots it may 
still be able to register with MAXCS even if the new phone password does not match the MAXCS SIP   
						

							 
Polycom Configuration Guide   Page 50 of 52 
registration password. This occurs because the phone reverts to its previous configuration when it is 
not able to register with the new password. 
 When a Polycom user is making an outbound call and the phone is in a ringback state, if a trunk call 
rings that extension then the call will go to the call waiting queue immediately. 
 On VVX1500, VVX600, and VVX500, When a Polycom phone enters power saving mode, the phone 
screen will be turn off. If the screen is off and Enable Splash Display is also off, then any outstanding 
BLF or Line Park calls will not turn the screen back on. In other words, the user may not know that 
there are some outstanding calls. To somewhat alleviate this issue, set up office hour and idle 
timeout to maximum to prevent this issue from happening too often.  
 Single call waiting is unsupported on Polycom phones. 
 Polycom phones will ring slightly longer than AltiGen IP Phones will, when you set the workgroup 
option “Number of Rings Before :andling” option. 
 Polycom phones, in some cases, behave differently from AltiGen IP phones. For example, if a Polycom 
phone is placing a call and another call comes in, if the user presses Answer to pick up the incoming 
call, one of two things will happen: 
o If the incoming call is an internal call, the incoming call will be answered and the outgoing 
call will be dropped.  This behavior is different from AltiGen IP phones. 
o If the incoming call is a trunk call (for example, over a SIP Trunk), then the incoming call will 
not ring the Polycom phone, but will go directly to busy call handling-personal queue. This 
behavior is the same as with AltiGen IP phones. 
#17 
 To allow users to use the #17 feature (station login into multiple phones), a SIP-Tie trunk is required 
in order to communicate with the server. 
 If you have the #17 feature enabled, you may have times when one or more Polycom phones may be 
using the same extension. This may cause conflicts if Enable Registration is selected, because that 
feature allows multiple Polycom phones to register to the Secondary Proxy at the same time. If this is 
a concern, you can uncheck the Enable Registration option. 
BLF and Line Park 
 If switching shuts down or if an extension is offline, the BLF for the extension will show as Busy. 
 On VVX models, if a user taps a BLF softkey twice (the second time while the call is ringing), the call 
may be disconnected. Tapping a BLF softkey twice on a SoundPoint model places the call on hold. 
 In some cases, if you change a BLF softkey setting on a Polycom phone, the phone may reboot twice. 
There may be a slight delay between these two reboots. If a call comes in between reboots, the agent 
can answer the phone and talk as needed; the phone will do the second reboot after the call 
disconnects. 
 If a VVX user is navigating through the screens (in other words, they are not on the Home screen that 
shows the BLF and LP keys) when a BLF or Line Park rings, and if their extension does not have the 
Splash screen feature enabled, then the Polycom phone will not show the BLF ringing status, and 
therefore, the call may be missed.
