Hello,

Does anybody got a working configuration to make an "attended call transfer" with a call through an Asterisk gateway?

Example:

PSTN --> Asterisk --> SER --+-- A |<---transfer call pstn to B +-- B

The call will come from the PSTN Network and will go through "A". A sets the call on "Hold" and calls "B". After A is connected with B, A hangup and B got the call from PSTN. This is not working at the moment. Attended call transfer only with OpenSER and only with SIP-Phones is no Problem. But if the is an Asterisk as PSTN-GW in the game it will not work.

this might be a routing problem or an issue in Asterisk. To be able to help more, please post the SIP trace for this case (you can use ngrep to catch the sip traffic on kamailio server).

Cheers, Daniel

Hello,

as you can see, the REFER is answered with 603 Declined. You can run Asterisk in debug mode to get more hints there. Probably the best is to ask on Asterisk mailing lists as well.

Cheers, Daniel

Thanks, this my trace:

Asterisk returns 603 for the REFER, this means that Asterisk doesn't allow it for *some* reason, but nothing to do with Kamailio.
