I'm trying to get a scenario working, thus far i'm not sure what i'm doing wrong - hopefully there are some examples people can provide.
I have a CUCM on the inside of the network (10.x) with a standard 2811 ISR acting as a PSTN gateway (FXO) plus that ISR also has a WIC-1ADSL for internet connectivity.
I want to bring in a SIP trunk from a provider, they can't really give me any configuration advice unless i'm using Asterisk. It appears I need to register with their SIP UA, and then they forward the calls to me.
Can I somehow bring this trunk in from outside the firewall to the CUCM or do I need to terminate this at the gateway an then send it through?
Any config examples would be quite helpful.
Will I need IPIPGateway to do this? If I do, going to an IPIPGateway load will this kill my PPPoA feature I need for the ADSL? (For some reason the IPIPGW loads don't have feature lists on CCO)
I'm sure someone has completed what i'm trying to do. The provider is Link2Voip.
