SIP trunk inbound calls.

[chevymannie]

I just setup a UC560.  I'm able to make outbound calls on my SIP trunk, but inbound is failing.  On the other end I get one ring and then a disconnect.  Support says it may be a providor issue, but I still find it strange that I can make outbound calls without issue.  Any thoughts?

Can you do a debug "debug ccsip messages" on the system?

Take a look at this thread:

https://supportforums.cisco.com/thread/2126887

Also, can you post full configuration of your system?

Hello,

Have a quick read of

http://www.voip.co.uk/ciscoccatoolsecurity/

This details how CCA protects your UC560 and you'll see why the 500 is being sent.

Hi Adam has this link been taken down

[chevymannie]

Thanks for your help.  Turned out to be the ACLs and credentials I was using for the carrier were incorrect.
