[cisco-voip] SIP Binding: Different Binds for Carrier vs Internal

[Matthew Loraditch]

Yeah I thought about that, but not my area of strength nor something I anticipate needing us to know down the road. The binding stuff seems to be sufficient for my needs.

I need to bind call legs to my carrier to one IP and all legs to CUCM on another IP on the same router and neither side ever see the other’s IP nor need to route to it

I’ve done something, at least similar, many years in the past but no longer have access to the environment to verify the behavior and am trying to refresh myself on the setting.

In that setup we bound the dial peers to the relevant interfaces and enabled allow-connections sip to sip and address-hiding in my voice service voip config.

Am I generally correct in all of my current thoughts? Anything I’m not thinking of?
