My customer want to have some abrivated dialnumbers on his Callmanager to reach Germany. There fore we use a *8XXXXX Pattern. Due to the fact the customer uses a 3 digit numberplan internal, i have to sent the *8XXXXX number with H323 to the Gateway, translate the number to the international number plan for germany and sent it back to the Callmanager.
Here a route pattern over MGCP sent it to the gateway MGCP controlled ISDN30.
The next problem occures.
Some times it works fine, other timer after 2x a ring at remote site, the calling party gets a busy. Dialing the number directly with the E164 numberplan works totally ok .
So anyone who has an idea?
