Hi,
I just moved many Polycom phones from firmware v3 to 4.0.1b. Anto-Answer
simply stopped functioning. I can downgrade and make it work, upgrading
kills it again. There obviously is a difference in how the newer
firmware is treating this auto answer sip header.
Can anybody tell me if they have Polycom firmware 4.x.x working with
auto-answer/paging? Just so I know it’s worth my time to investigate, as
opposed to knowing it`s a Polycom firmware bug? If so, did you have to
make any changes to the SIP header sent to make Polycom phones auto answer?
I would second the others suggestions about rewriting the configs.
Polycom made extensive changes between 3.2 and 3.3, and I think they
made a fair number of changes between 3.3 and 4.0. I have two phones
that I've upgraded to 4.0.1b for testing, a 550 and a spectralink 8440,
and I believe I have auto answer working as you describe. Here's the
pertinent snippet from my config:
<polycomConfig>
<voIpProt>
<voIpProt.SIP>
<voIpProt.SIP.alertInfo
voIpProt.SIP.alertInfo.1.class="ringAutoAnswer"
voIpProt.SIP.alertInfo.1.value="intercom"
voIpProt.SIP.alertInfo.2.class="ringAnswerMute"
voIpProt.SIP.alertInfo.2.value="page"
voIpProt.SIP.alertInfo.3.class="autoAnswer"
voIpProt.SIP.alertInfo.3.value="silentanswer">
</voIpProt.SIP.alertInfo>
</voIpProt.SIP>
</voIpProt>
</polycomConfig>
I have also added an <se.rt> section to adjust the ringer and timeouts
for these ring tones.
