Poly VVX400 Pging from Broadsoft.

I'm trying to get a VVX400 to auto answer from broadsoft. I registered a 650 on 3.1.3c with the same account and the same invite does auto answer. 


The invite includes this line: Call-Info:<sip:>;answer-after=0


Its not coming in as an alert-info but rather Call-info. How can I get my VVX400 running 4.1.4 to recognise this and answer the call?



650 is using:



I have tried many variations of value and class on the vvx.

Hi Leo


Not sre if this helps but we set auto answer SIP calls in the phone%BWDEVICEID%.cfg:


<call.autoAnswer.SIP call.autoAnswer.SIP="%AUTO_ANSWER_SIP%" />


Then added a tag under polycom tag sets default set to 0 (off)


Then under the user add the tag with a value of 1 which overides the system default.


Hope this helps somewhat....

Hello leo,

welcome back to the Polycom Community.

The community's VoIP FAQ contains this post here:


Oct 25, 2011 Question: How can I change my Ringtone or Ring in a special manner for a certain incoming call?

Resolution: Please check => here <=


Since UCS some parameters have changed and you may want to try voIpProt.SIP.alertInfo.4.class="answer"/> instead of voIpProt.SIP.alertInfo.4.class="3"/>.


You could also try UCS 4.1.5 or even 5.0.1 and ensure you check the phone logs as well.


If this still fails please work with your Polycom reseller and/or Polycom support directly and quote VOIP-68300 which was an issue in the past.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
