Birger "WIMPy" Harzenetter commented on PRI-177:
------------------------------------------------

Ok that was "luck" again.
The phone that rejected the message was a Hagenuk, and an Ackermann PBX did the same, An Ackermann phone however just silently ignores it.
Phones by Ascom, FMN and Siemens did ring.
So the specs have been interpreted in different ways.

But it certainly wouldn't hurt to suppress the whole CDPN IE if the CDPN is empty. That should always work.

> When trying to send a global call to a NT span, a called party number IE is generated without a called party number, or in other words octet(s) 4 is/are missing.
> Correctly the whole IE should be absent in this case.
> The syntax of the dial string does not matter. Tried group or channel, with or without trailing /.
