i have cucm 12 and i have configured all phones when calling outside pstn through sip trunk to show a certain number
in the DID range for like 23334000 but whenever it callls outside it shows 23334444 which also another number in the customer DID range , so where does the fault lies here? is it from my side or the sip trunk service provider side?
i uploaded the log from RTMT to the collaboration solutions analyzer but i cant seem the find the place where it shows the used external phone number mask?
i got it solved , it turns out under route patterns im using , i need to to tick the "user phone external phone mask" or something
