CME-------------UCM-------MGCP GW with PRI

[renji joy]

Hello Team,

Here is our scenario ,

CME-------------UCM-------MGCP GW with PRI

Here we want make the call from cme to outside organisation(PSTN),which should use the same PRI in HQ.

we  have configured the VoIP dial peer and pointed to call manager but call is not going to outside.

if we are missing something and please suggest the same.

Thanks in Advance

Please check version of IOS on your router.If it is above than 15.x may be it is Tall-Fraud prevention (security feature)  

You should permit ip address from which calls are coming (Your CME VOIP interface) on router. Configuration as

Voice service voip

Ip address trusted list

ipv4 x.x.x.x

Otherwise U can configure settings so that CME will call via UCM (in my opinion it so more clear and secure)

It is good but .....

Please check version of IOS on your router with E1 interface.If it is above than 15.x may be it is Tall-Fraud prevention (security feature)  

You should permit ip address from which calls are coming (Your CME VOIP interface) on router. Configuration as

Voice service voip

Ip address trusted list

ipv4 x.x.x.x

I mean You can configure UCM and CME so, that CME IP Phone call to outside it works so

CME - UCM - E1 on another router
