All phones are registered in context “phones” and are set to not allow reinvites.  All phones can dial each other directly.  The dialplan looks as follows:

> [phones]

 Exten => 5253,1,Dial(SIP/5253,10)

 Exten => 5878,1,Dial(SIP/5878,10)

 Exten => 101,1,Dial(SIP/101 at audiocodes,10)

  

> Transfer fails regardless of the order (101 calls 5878, 5878 transfers to 5253 or 5878 calls 5253, 5253 transfers to 101, etc)

Hi Jake,

I don't have the answer but I did look at your trace and something about the way the transfer is being done from your phones is not quite right. You're calling 5253, then calling 5878 and then requesting a blind transfer of 5253 to 5878. However at that stage 5878 is already on the phone. I suspect the transfer should be being requested as an attended one not a blind one.

Regards,

Greyman.
