[asterisk-users] Disabling QSIG Encoding in LibPRI

[Armen K]

Hi Richard,
Thanks for that (must be late where you are)  so I've set "header.nfe_present" to equal "0" as it was "1" before and that indeed removed those encoding bytes that I was referring to but........... sadly, I've had no luck getting the caller name to show up.
I'm really not sure what's going on...  I think I'm working in the dark right now because I would need to see how other people with Nortel BCMs are getting this to work.  I put up a posting on tek-tips to see if someone can send me a screen shot of their BCM Monitor when a call comes in with a Name so I can see what the system needs to see.
This also leads me to believe that there's another reason why the name doesn't show up when I use "euroisdn" signalling... because in Nortel's BCM Monitor, I can see the element:  CCITT Display come up as follows but still no luck.. here's a screen shot with caller name "Ma Bell" being sent out... the HEX characters are there but for some reason the format that it's in doesn't make it recognise them or something.

(SIGH) ... well I'm going to take a break for today.
Cheers,Armen

Hi everyone,
I was referred to this mailing list by Richard Mudgett regarding the following thread on Issue Tracker as it's a feature request and not a bug:
https://issues.asterisk.org/jira/browse/PRI-170
We've got a Nortel BCM (actually 2 BCM50s and 1 BCM400)... all showing the same problem.

When a call comes in the number shows up OK but the name does not.  In looking at the ISDN messages coming in, we've noticed that the Facility IE for the name has been QSIG encoded.  However, the BCMs don't understand this encoding and as a result the name does not come through.

Basically, I need to figure out how to disable the encoding so the Facility IE for caller name comes through without being encoded (in other words without the AA 06 80 01 00 82 01 00 bytes being placed between the 9F and 8B bytes.

For example:9F 8B 01 00 A1 0E 02 01 08 02 01 00 80 06 4D 61 20 42 65 6C 6C

In libpri pri_facility.c:enc_qsig_calling_name() you can change the code to not set any
header values nonzero.  That will disable sending the optional NFE and
interpretation-APDU values for the calling name only.
