SIP-NNI peering with PBX with NAT L3
Hello,
We have the following scenario:
PBX---------NAT L3-------SBC----softswitch core
if the scenario is using SIP-NNI mode and not UNI mode will it work and how?
Will there we problem of RTP to phones behind the PBX?
if the SIP L5 and L3 are different how will be the configuration on SBC will local-policy include L3 address and session-agent L5 address?
Thanks,
Hugo
