are you not better off sticking a Gatekeeper in the middle, that has knowledge of all 2 PBX's and your Call Manager

Sorry for this delay , but this to ask about the reason to GK with analog PBX's.

thanks,

Ahmed Ellboudy.

Two scenarios:

1) Say PBX A is 1000-1999, PBX B is 2000-2999 and CUCM is 1000-1999. If you want PBX B only to be able to call PBX A, then you simply put the 1000-1999 DNs in CUCM in a partition that isn't reachable from the CSS of PBX B's gateway. This only works if you don't need for the users to be able to get to the overlapping extensions.

2) Otherwise, you have to use codes like you are doing now. You would create a translation pattern for the code, and that translation pattern would strip the code off and the translation pattern itself would only have a CSS able to reach the numbers for that code.

Basically, just use prefixes.

Dear nick,

sorry for this delay, can you clarify the two scenarios, take in consideration that the two gateways one connects PBX A with the call manager using E1 card installed in first gateway and the other connects PBX B with the same call manager with E1 card installed on the 2nd gateway.

Thanks,

Hi, if you're nor familiar with voice networking, recommend you hire a reputable person for the job, otherwise it can be very difficult and frustrating for you to accomplish the task.

Dear, I am a voice engineer but I need a detailed information to do that.

Dear, a voice engineer would be done already, as it's quite simple.

Dear , I see you have a good experience in VOIP system and you see this issue before but this is the first time facing this issue ,so I ask for support,any way thanks for your support and I will search to make it.

Dear, your misuse of the rating system clearly shows your frustration at being unable to configure that project.

You wanted someone else to resolve it for you, and for free. Sorry, but that doesn't happen all the time. Good luck.
