Paging Intercom on polycom 335

System Info
PBX Firmware: 6.12.65-28
PBX Service Pack: 1.0.0.0
FreePBX 12.0.68
Polycom 355 is version 4.0.3.7562
Asterisk 11.18.0

So I have been having this issue for a while and started to try to figure out what might be happening and try to fix it. I have 22 Polycom phones which (10 - 335) , (10 - 450) and (2 - 650). I have 9 335 that work with auto answer and one that doesn’t.
What I have tired and read.

  1. In the Extension’s module, I have the intercom enable.

  2. In advance settings i have force intercom “Force All Internal Auto Answer - True”

  3. Also have Internal Auto Answer Default ( enabled)

  4. I have also a) remove the config from the End Point Manager ( and checked the tftpboot folder to ensure all config files for that MAC are gone.)
    b) re generate the config
    c) then default the phone several times.

  5. Here is what i have tried to input on Endpoint manager on phone that doesn’t work.

</voIpProt.SIP.acd>
<voIpProt.SIP.alertInfo
voIpProt.SIP.alertInfo.1.value="Auto Answer"
voIpProt.SIP.alertInfo.1.class="autoAnswer"
voIpProt.SIP.alertInfo.2.class="ringautoAnswer"
voIpProt.SIP.alertInfo.2.value=“answer”

Here is the input of a 335 that works. I have tired this on the one that doesn’t work, still no go.
</voIpProt.SIP.acd>
<voIpProt.SIP.alertInfo
voIpProt.SIP.alertInfo.1.class="ringAutoAnswer"
voIpProt.SIP.alertInfo.1.value=“Auto Answer"
voIpProt.SIP.alertInfo.2.class=“default"
voIpProt.SIP.alertInfo.2.value=””

I have scoured the internet for 3 days and can’t find any other info on this problem. Any help is appreciated.

Here are log files of extensions 128 that does not work.

how are you generating the config files? use wireshark to see what code FreePBX is sending out and look at the config files for the polycom phones in question. i suspect you will see the mismatch pretty quickly. we have run into this on systems with the oss endpoint manager. the paid endpoint manager also has the same issue with older polycom phones like the 500’s.

I am generating the config through Paid end point manager. I will check out wireshark see what i get.

Did you find the solution to this problem?
