Re: Need help in connecting two CMs throught pt 2pt for 4 digit

u can do it in several ways

u can make what is called inter cluster trunk ICT which connect the two CMs directly and when u make for example a route-pattren to that company

like 1XXX

and on the gatway or route list chose the ICT u creat it which contain thier CM IP

and also they have to do the same thing on thier side in opest direction

they have to make route=pattern with 2XXX

or

u might have a gateway H323

and IP connectivity either with thier gateway or CM

make voip dial-peer point to either thier gateway if they use a gateway or directly to thier CM in this case they have to add ur H323 gateway to thier CM

for example lets say thier gateway Ip 1.1.1.1 and they need from u to dial the extentions directly without adding any more digits

on the h323 do

dial-peer voice 1 voip

destination-pattren 1...

session target ipv4:1.1.1.1

with h323 when u do this also do the following command

voice service-voip

allow connection h323-to-h323

the following link for ICT config (useful)
