Cisco 2651XM router connected to the internet
7940G ip phone(s)
I have a sip trunk running on my above router that worked fine when registering with tescointernetphone.com, but I decided to give sipgate1000 a try. In the router config I changed the sip-ua registration to sipgate.co.uk and the sip trunk registers fine to sipgate but I can't make outgoing calls, I get the engaged signal all the time, even if I dial voicemail (50000). But I can get incoming calls. The settings in my router worked fine when dialing out on tescointernetphone but the same settings won't work with sipgate, even though the sip trunk registers with sipgate.co.uk. I know it's a problem with my router config because if I use xlite on my pc registered to sipgate.co.uk I can dial voicemail without any problem.
One thing worth noting is that my tesco username is actually my tesco DID number, but my sipgate username is just a 7 digit number.
Attached is two configs: one is the running config when registered with tesco, the other when registered to sipgate.
thanks for any pointers.
