Dear All,

I hope this email finds you well.

Writing to you Nuri Alfeet from Hatif Libya company ( HLC ),

 We Has been providing service to several companies by linking (E1s) and programming (ISDN-PBX) which works well except
It's when you connect Mobile Phone call recipient does not appear to have the caller ID shows it has a number of main switchboard.

 The scenario goes as follows:

All 30 lines line in this E1 has unique number and will be dedicated to separate phone, so each phone should be able to make and receive calls using its unique number, but while testing

the E1 connection, we found that any calls placed from any extension end up using only one extension instead of using its unique extension. for example, when placing a call from extension

3660111 to my mobile, the caller-id on my mobile shows that the calling number is 3660101. Same applies to all other lines. It looks like the configuration on the PSTN side is ignoring

call details sent and replacing it with 3660101.

Could you please assist me to solve this issue.
