Richard Mudgett commented on PRI-170:
-------------------------------------

Libpri will also send the CallingName facility with the NI2 switch type configured.  With NI2 a facility ie is put in the SETUP message indicating that the CallingName will follow in its own FACILITY message.  Since you have a Nortel PBX it probably supports DMS-100 and NI2.

> Asterisk server (12.2.0) acting as *pri_net* to a Nortel BCM PBX via an E1 EuroISDN connection, using QSIG as the protocol:
> There are a number of bytes which are sent during the Caller name Facility IE  that seem to be confusing the PBX and as a result it ignores the entire string, resulting in the caller's name not showing up at all. Is there a way to disable transmission of these bytes?
> In other words, instead of Asterisk sending out:
> {{9F AA 06 80 01 00 82 01 00 8B 01 00 A1 0E 02 01 08 02 01 00 80 06 4D 61 20 42 65 6C 6C}}
> Can we disable the transmission of the bytes {{AA 06 80 01 00 82 01 00}} so transmission is this instead:
> {{9F 8B 01 00 A1 0E 02 01 08 02 01 00 80 06 4D 61 20 42 65 6C 6C}}

> As an aside, here's an interesting Cisco telephony blog article which has an example of this Facility IE without those 8 bytes, showing  
> {{Facility i = 0x 9F 8B 01 00 A1 0E 02 01 08 02 01 00 80 06 75 73 65 72 30 31}}
