[cisco-voip] VoIP transit call

[Sumiya]

Hi all, 


My gw1  is working with destination gw2(partner)  directly.
Gw 2 accepts only gw1 ip address.  

I  want to send calls from my gw3  to gw2  via gw1. 
Gw 1 will be transit gw. All gws are Cisco5300.

But gw1 is releasing all calls (h323 cause code =3). 

Please help me How i can make transit calls via GW1. 


I did like below. 

Gw3 : 
dial-peer voice 33 voip
destination pattern 123T
session target ipv4:gateway1-ip-address

Gw1 : 
dial-peer voice 11 voip
destination pattern 123T
session target ipv4:gateway2-ip-address

Gw1 : 
dial-peer voice 11 pot
destination pattern 123T
port 0:0
