[asterisk-bugs] [JIRA] (PRI-170) Way to disable ASN.1 bytes being sent out

[Armen Karlozian (JIRA)]

     [ https://issues.asterisk.org/jira/browse/PRI-170?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Armen Karlozian updated PRI-170:
--------------------------------

    Description: 
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}}

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 I disable the above bytes so it sends this instead:
{{9F 8B 01 00 A1 0E 02 01 08 02 01 00 80 06 4D 61 20 42 65 6C 6C}}

The 8 bytes enclosed in the blue rectangle are those I'm referring to.
