Hi,

If you are using FXO line on MGCP gw with CUCM earlier than 8.0 , then there is no work around as it is a bug solved in 8.0

If no, check if you have got caller id display service from your telco or not ?

If not, please describe your netowrk components in more detail

Hi Guys,

Thanks for all your reply.

I want to let you know that we have almost 300 users in that location and we have problem only with this user. If there is a problem with the caller ID display from Telco or in the gateway or in TP then the whole users should have affected.
