Title: SIP Server vs Polycom Handset - Auto Answer
Post by: Dionysis on November 16, 2010, 03:23:06 AM: Hey guys,

I'm trying to get a Polycom IP430 handset to auto answer when registered as an extension on SIP Server.

I've read the manual and I know that something needs to be sent in the "Alert Info" of the INVITE message, and that it's something to do with the "ring type". But I can't for the life of me figure out the syntax to use.

Anyone got any experience with these handsets?

Check the SUGAR CRM integration mode, in this way using Alert-Info: RANR may work...not 100% sure what might worth trying it

Looks like it can't be done without the ftp configuration files.

I already use this

Post by: Dionysis on December 03, 2010, 10:55:33 PM: olol, the TAnswerCall function is not supported by SIP Server to the best of my knowledge, otherwise this would be a quick win.

I have now got the phone to auto answer using the sip.cfg files downloading from an FTP server. To do this you need to do the following:

1 - edit your sip.cfg to contain the following 2 lines.
<alertInfo voIpProt.SIP.alertInfo.1.value="ring-answer" voIpProt.SIP.alertInfo.1.class="4" />
and
<RING_ANSWER se.rt.4.name="ring-answer" se.rt.4.type="ring-answer" se.rt.4.timeout="2" se.rt.4.ringer="2" se.rt.4.callWait="6" se.rt.4.mod="1"/>

2 - add custom SIP Headers to have "Alert Info: ring-answer" on every call to the extension. For outbound calls you need to use the make-call-alert-info option in SIP Server.

et voila!

Auto Answer.

However, I'm still struggling with some functionality. When you transfer or conference a call the handset sees a new call arrive. Which does not get auto answered with my config. So my Inbound and Outbound calls work but transfers and conferences are not.

Anyone got any ideas?

Set dual-dialog-enabled to false on the DN and everything is good.

Post by: cmax on December 16, 2010, 07:26:01 PM: I'm following along here.... step 1 is fine.... Step 2, the custom SIP headers I'm a bit lost. Any details on how to perform this function?

Thank!

Post by: cmax on January 11, 2011, 06:05:18 PM: I didn't receive any replies so we figured another easy way to do this. Using the multi assign function in IRD, try calling ExtensionAttach['Alert-Info','<auto-answer>'.

This will attactch data to the call, which you can manipulate to send thru the invite message.
