3CX Phone System Version 3.1.2434.0
Cisco 2811 Router with ISDN PRI
Cisco 7941 Phones
I have not been able to successfully complete transfers with Cisco phones and 3CX. In the scenario displayed in the packet capture below I have received an incoming call from 9072223333 on an ISDN PRI line (10.1.3.13) and it is answered by 2224444. 2224444 (extension 4444) transfers the call to extension 4419. Outside caller begins to hear music on hold. 4419 answers call but now also hears the music on hold. Message on 4444 indicates “cannot complete transfer”. And complete transfer never occurs. I have tried every available setting on the advanced options for the ISDN gateway.
I have tried Alpha 4 and do not get the 3CX error below and occasionally do get successful transfers, but most times not.
In the 3CX Log below I do not understand why the To: is 907222333 when that is the outside caller number and the call is being transferred to 4419.
I would appreciate any help someone could provide.
