Gamma IP Auth

[ian rowan 0]

I am trying to use the IP Auth service provided by gamma, I can call in without issue but when I dial out I get call rejected

 

I spoke with the ITSP and they said the from header had the private IP and not the public address

 

i changed the SIP IP Replacement list to "192.168.0.10\public IP" and that allows me to call out but I still get no audio

 

any one else used this service from Gamma?

Well, this a famous problem called "NAT". Most service providers today use a "SBC" (Session Border Controller) to solve it, so that customers dont have to deal with it and all th tricky technical topics and instabilities around it. There is a reason why ACME packet is one of the hottest companies in the VoIP world!
