I've got a CME router IOS 12.4(9T) running as a SIP-UA into a service providers SIP network.
I was running 12.4(8a) and the registrar timers was fine. Every 25 seconds or so it would renew my registration.
I changed to 12.4(9T) because I needed the ability to rename the local sip domain to be able to make calls out, not just call in. Ever since that, my registrar timer renews every 60 seconds instead of 25 seconds. This is a problem because the service provider requires a renew every 30 seconds or I get a 403 forbidden when I try to call out more then 30 seconds after renewal.
The only timers i've seen for SIP registration was the retry timer which is 100-1000ms. Obviously not applicable
The other time is the expiry time on the
registrar dns:x.y.z username test password test expiry seconds
Which doesn't seem to affect anything at all
If anyone could be of assistance, i'd be very grateful
It seems like you're always helping me out these days! I've fired up 12.4(11)XJ3 with the same result that 12.4(9)T and 12.4(15)T gave me. The lowest I can set the expire time to is 60 seconds.
I'm just finding it really strange how 12.4(8a) drops the timer down to 25 seconds to match the SP 30 seconds expire. Shame I can't stick with that IOS - I need the voice-class sip localhost command in the technology release for successful calling out.
My sympathies, I understand your frustration. In total frankness, the SIP-UA part of Cisco IOS, is substandard respect to general level of the code.
Your only hope is to submit a case, and ask for a bug to be opened as "feature request" or something like that. On your side, you have that is was working before, so actually the new code broke something.
Then with patience, one can try to get it thought to feature developers and managers and see if something can be done about it. But, don't hold your breath.
