Thanks for the response, but doesn't this solution still require the pbx to send an alert-info within the SIP messaging? Sorry if I am being dense, I don't normally work on the endpoint side of things. On cisco phones (on sip) for example I can select which line I want to have auto-answer and regardless of the alert-info being present or not it auto-answers.

The recommended definition for Ring Answer is listed below:

<alertInfo voIpProt.SIP.alertInfo.1.value="Ring Answer" voIpProt.SIP.alertInfo.1.class="4" />

<RING_ANSWER se.rt.4.name="Ring Answer" se.rt.4.type="ring-answer" se.rt.4.timeout="2000"

se.rt.4.ringer="2" se.rt.4.callWait="6" se.rt.4.mod="1"/>

The alertInfo.1.class in this example is set to 4. As you can see the 4 corresponds to the se.rt.4 ring

type. You can replace 4 with some other number to specify a different ring type.

Has anybody had any success trying to get polycom phones to auto-answer without being sent an alert-info header? I am trying to get 1 line on my polycom 550 to auto-answer every call every time. Any thoughts

Thanks in advance. Peter Fabian | Senior Voice Engineer | Telesphere | P: 4803857059 | F: 4803857079
