Mivb to unify X8 on sip trunk - caller id issue

[abmitel]

Hi
we have interconnected MIVB AX controller with unify X8 on sip trunk .
PRI is connected on MIVB .
the extension number and DID number series range of PRI is different .
my incoming from PRI and from Sip trunk are ok.

problem is during outgoing call
when MiVB extension calls X8 extension we get correct caller id .
but when Mivb extension calls using PRI the outside party gets pilot number .
if i resolve the pri number issue then during sip trunk call with x8 the caller id displayed on x8 user is the pri did number and not the extension number

please suggest

Caller ID can be setup on the actual link and that way you can set a different number format going over PRI and SIP.

Think cpn per did on the sip might work
