[cisco-voip] ccm and Service Provider PAT Port AllocationEnhancement for RTP and RTCP

[Voll, Scott]

If I understand correctly you are using two Ethernet ports on your CM.
This is not supported.

 

If I misunderstand my apologies.

hi

 

design : ccm 4.1.3  have 2 ip address one private and the other one
public.

private ip is behind the firewall.

 

i gave public ip address to CCM for 2nd ethernet and putted the beyond
the firewall .also I  added a new h323 gateway  for voip service
provider's h323 gateway .

when i try to make a call from voip provider's backbone the remote side
ringins but there is no audio ,

because there is no rtp stream from my ip phone. Because ip phones have
private ip

so is it ok if i nat the ip phones on my internet router?

also i read a documents related to Service Provider PAT Port Allocation
Enhancement for RTP and RTCP   and session border control ..

how to i nat ipphones .  

can  i use the config example in the document below in my INTERNET
router?
