Cannot make call across H323 PRI to nortel from some phones
I am running into a weird issue. We have an h323 gateway with a PRI connected to a PBX for calls between the cisco phones and Nortel phones.
From most phones it works. However some phones it does not work. I even found a scenario where a users softphone works and their desk phone does not work. same extension, same callerid, same calling search space. Calling the same number
The error we see is
Cause i = 0x81D8 - Incompatible destination
from what I read it says that the number does not exist on the switch side. but it obviously does as we can call it from other phones going across the same PRI.
Below is the debug. the top is from their softphone and matches what I see from working desk phones. the second debug is from his deskphone
From working phone
