SIP NAT

Unanswered Question

Hello all!

I have a strange problem, trying to use SIP over PAT. In my SIP program I cann't change client IP address. I see that statring 12.2 IOS support NAT SIP without any additional configuration. How can I disable it and using simple NAT without deepper SIP packet changing

192.168.10.x - inside local, 11.11.11.11 - outside local.

deb ip nat trans sip
