[asterisk-users] Polycom and auto answer

[Bob Pierce]

Here's what I have and it works for me in 1.8.5:

in sip.cfg
<voIpProt>
  <voIpProt.SIP>
    <voIpProt.SIP.alertInfo
voIpProt.SIP.alertInfo.1.class="ringAutoAnswer"
voIpProt.SIP.alertInfo.1.value="Ring Answer"
voIpProt.SIP.alertInfo.2.class="autoAnswer"
voIpProt.SIP.alertInfo.2.value="Auto Answer" />
  </voIpProt.SIP>
  <voIpProt.server voIpProt.server.1.retryMaxCount="0" />
</voIpProt>

in extensions.conf
exten => 3500,1,SIPAddHeader(Alert-Info: Auto Answer)
exten => 3500,n,Page(SIP/3011&SIP/3021&SIP/3110) ; Shortened for
example. I actually have about 20 phones here.
exten => 3500,n,Hangup


This is working fine in an environment with many 330s, some 450s, some
335s and a 550 all running 3.3.1

Hope this helps you out.
