Sip Profiles

Jonathan Forbes
Beginner
Beginner

I have a cisco 2911 voice router set up for sip trunk to provider. 

 

I am running this behind a nat device and trying to get sip profile to rewrite the private ip to the public ip. 

 

I have set this up with applying the sip profile to my dial peer. The provider still says i am send the private ip address to them in the sdp header and the sip header 

 

any help would be great. 

 

voice class sip-profiles 100

First thing, this needs to be done by an ALG. Second, you should use the SIP Profile Test tool to test your profiles against the SIP message -

Do you mean sip alg from my firewall or from my router?

 

Thanks

 

Whatever the NAT device is, presumably a firewall. It needs to support SIP protocol inspection and rewriting (aka ALG). I do not believe a SIP Profile will be sufficient to get this done on the CUBE router itself, though you could perform NAT natively on that router instead of an external box.
