Outgoing SIP calls

Unanswered Question
Jan 20th, 2008

Hi,

Am attempting to get outbound calls via SIP to my ISP working, inbound SIP works fine.

Calling an external number gives an error tone on the handset.

The objective is that all calls except emergency (000 in Australia) go out via the SIP service. 0 (zero) is dialed to make an external call. My SIP provider is: sip.internode.on.net.

I've attached the config, and the debug cssip calls log is provided below.

What I've been able to glean from the debug is that either the number isn't being translated correctly since the leading zero (0) is supposed to be stripped, or that my end has been unable to negotiate a protocol with the external sip server, or both.

I have a UC520 with c500-advipservicesk9-mz.124-11.XW4.

All help appreciated.

The problem is now 90% fixed.

Problem one was that I was sending the internal extension no. to my ISP and they wanted the telephone number of the service.

Second was that the number translations were wrong.

I can now make calls but only if I dial the area code. If I try to make local calls without the area code the call fails.

Following is the translation ruleset:

voice translation-rule 2

rule 1 /^09/ /039/

rule 2 /^05/ /035/

rule 3 /^0/ //

Applied to:

voice translation-profile SIPOutgoing

translate calling 3

translate called 2

And when testing this is the result:

test voice trans 2 052554616

Matched with rule 2

Original number: 052554616 Translated number: 0352554616

Original number type: none Translated number type: none

Original number plan: none Translated number plan: none

cellardoor#test voice trans 2 00352554616

Matched with rule 3

Original number: 00352554616 Translated number: 0352554616

Original number type: none Translated number type: none

Original number plan: none Translated number plan: none

As can be seen both numbers produce the same result but the former does not work and doesn't even get into SIP (nothing shows in ccsip debug all for that call), but the latter does work.

Any assistance appreciated.

The problem is now fixed completely to the point where a zero "0" doesn't need to be dialed to get an outside line which is fine for this very small install.

The reason why it wasn't showing in the debug was because the number was the incorrect length for the dial-peer rule I had created.

All good now.

BTW anyone is Australia trying to use CCA to set up one of these boxes - don't. There is a bug which mucks up the dialing plans in the config. The bug is apparently known by Cisco. I believe it is to do with our use of 000 for emergency, and our traditional use of 0 for outside lines.
