Hi All, I was wondering, in my effort to show how Asterisk can replace Call Manager, if there is support for call transfers/forwarding from the users Cisco 7940 SIP phone to either another SIP client or through the AS5300 on to the PSTN. I do see some stuff in the docs but seems to be specific to a local PRI board in the PC of which I don't have. Any experiences/comments most appreciated.

[Asterisk-Users] SIP Call Forwarding/Transfer support ?
Hello Adam,
i am doing some testing in the same direction. I want to use
Asterisk with Cisco 7960, Grandstream and Pingtel SIP phones. For
receiving and terminating calls i want to use the Nikotel SIP
service.
Until now i had no luck in getting the Cisco 7960 phone to work.
But with the Budgetone Grandstream phone i could receive and make
calls. Blind call forwarding also worked.
I think the reason for the 7960 not working is a bug in the
Asterisk. Something with a wrong Cseq.
Regards,
Christian.

Hielke - Cisco 7960 phones work quite well with Asterisk and SIP, and I have been using them for many months now, both on my own systems and those of my clients. Perhaps you can forward your configurations and I can help debug. The only functions I have not had working 100% are: parking via the "transfer" button on the phone, and peer-to-peer SIP calls (I have to set canreinvite=no on the config settings for the phones) JT>Hello Adam, > >i am doing some testing in the same direction.

Hielke & John, I too have the 7940 phones working perfectly in my setup with the exception of 7940's that are NAT'd when SIP'ing towards the AS5300 and then I find one way voice path but strongly suspect the mini firewall's we are using but am yet to debug this. John has some example configs on his site which were a good help in getting me started and am sure will help you: http://www.loligo.com/asterisk/ John, you mentioned transfers and this is my obstacle at the moment, could you share any more insight to your setup on this ?
