Cisco 8861 on Asterisk

[chrisukgreen]

I have a Cisco 8861 loaded with the SIP firmware which I can get to work with Asterisk for one line but cannot get it to work for more than one line. It tries to register and can receive inbound calls but cannot make outbound calls. Has anyone got this phone working with Asterisk/Elastix?

This area is Video Over IP, you may want to move this, or try posting on voip.org or similar sites for non-cisco call control.

Can receive inbound calls but not make outbound calls?  

Check your inbound and outbound proxy configurations in your Asterisk box.  Your inbound proxy details should be exactly the same as your outbound proxy details.
