[Freeswitch-users] Auto-Answer based on Call-Info from originator

[Peter Hillier]

Excellent point about a prefix. But I am intrigued by the comment that I can check using a condition such as a header value on a per call basis. I will google this and see if I can find some examples. I was not aware this could be done.

Can I do something similar to pull the call back from a device? So if a call is established to ext 1000 can I send something (prefix or x-header) to make Freeswitch transfer that call to me? Kinda like call pickup except that call is active so ext 1000 will get a BYE and no longer be in the call.

Thanks for your time Steven. This really helps out.

You could check the condition against something from the originating phone including a custom X header, or a prefix you strip from the number before dialing...

The problem is that "the calls I want" are dynamic. It has to do with proximity based features. This is why I want the originating phone to decide when to request the auto answer or not.  So from a dial plan perspective I cannot pre-configure this behaviour.

Basically I own both devices and I am moving the call from my mobile VoIP client to my SIP deskphone. I want it to be seamless with no ringback or alerting introduced (hence the reason I am looking at auto answer).
