Alcatel Unleashed

HI,
System release R8.1 (which was connected to PTC "public Exchange E1 CAS" via a PCM R2). Trunk Group Mixed ; signaling type is R2/MF and trunk COS is 28 every thing lookslike working fine at test level
We have another PBX SELTA coonected to this OXE via E1 in QSIG . when a do a call from PBX SELTA to PTC via a PCM R2 . the caller ID appear with number of extention telephonique .
Is there any paramétre to change it in QSIG trunk ?

Please Can Some one Help me .

hi Mokhtar
reverse did is not working, your oxe should transcod the selta extenstion according to did rules or at least should present installation +supl inst number if extension has not a did number .
put traces for same call at the two links
from selta to oxe qsig level T3 must be used
from oxe to PSTN r2 traces .
may be something wrong in the qsig trunk or selta's users wrong config at oxe's Prefix plan
