-------------------------------------------------------

When set to *DMS100* config it is only sending out Display IE and no Facility IE which is required by the BCM.

When set to *National (NI2)* config it sends out a Facility IE with name but it comes _after_ the {{CALL PROCEEDING_CC}} and {{CALL ALERTING_CC}} messages which may be the issue there?

When set to *QSIG* it sends out the Facility IE with the name during the {{SETUP}} message _but_ with the 8 encoding bytes in between byte {{9F}} and {{8B}}:(again copied from CLI debug)
{noformat}Facility (len=39, codeset=0) [ 0x9F, 0xAA, 0x06, 0x80, 0x01, 0x00, 0x82, 0x01, 0x00, 0x8B, 0x01, 0x00, 0xA1, 0x17, 0x02, 0x01, 0x01, 0x02, 0x01, 0x00, 0x80, 0x0F, 'ARMEN KARLOZIAN' ]{noformat}

> 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
