Skype SIP Trunk Outgoing Calls Fail and access to CUE.

networkwise · ‎12-01-2010

Hi,

Hi,
I have a UC540 configured with a Skype sip trunk. The trunk is registered with Skype. I'm unable to make outgoing calls. I configured the trunk using the latest version of CCA and followed and updated PDF doc for the Skype config. Incomning calls are working to a Skype online number. Im unable to make outgoing calls, and the the message button on the IP phones 7960's and CIPC running SCCP has stopped working. I ran debugs the output is below. First debug is an outgoing call second debug is an attempt to access voice mail when hitting the message button, this equates to connecting to cue at extension 399. Any advise would be appreciated. I have also attached a config comparison of the original working config and the config after the Skype CCA config ws applied.

Thanks
Andy

Below here is an outgoing call debug

Hi,

Well I figured why the outgoing calls were failing. It turns out that Skype will except a 10 digit there needed to be a 1 in front so 11 digit. I was trying call a local 10 digit number 303-xxx-xxxx and the call was failing, in my local area 720-xxx-xxxx is also a local 10 digit number. Any long distance numbers where I inserted a 1 were working, for example 1-408-xxx-xxxx. The solution was to edit the outgoing translational rule to add a 1 before the two local area codes of 303 and 720. See below.

voice translation-rule 1112
rule 1 /^9303/ /1303/
rule 2 /^9720/ /1720/
rule 3 /^9/ //

The above rule adds a 1 in front of the 9303 and removes the 9, same for 9720 it adds a 1 in front of the 9720.

The voice mail problem still exists but that I have to do some more digging.
