Cisco 7960 Call Transfer Problem


I have just done a fresh build and install of Asterisk / Zaptel / LibPri v1.4 on a clean install of Ubuntu. I have a TE120P PRI ISDN card.

Everything is configured and I can make and receive internal and external calls fine.

However, when I try and transfer a call from one internal extension to another, the transfer fails (regardless of whether the call is external or internal).

Note that the same hardware did work perfectly in a previous installation of the software (possibly Asterisk v1.2??).

The version of Asterisk I am running reports itself as Asterisk SVN-branch-1.4-r95577.

Below is some asterisk output from a scenario where we’re trying to transfer an external call from one extension to another.

Any help on this would be greatly appreciated as my staff are having to walk around the office a lot to answer calls at the moment!!!
