[asterisk-bugs] [JIRA] (PRI-177) Global call generates CDPN IE with invalid contents

Birger "WIMPy" Harzenetter updated PRI-177:
-------------------------------------------

    Status: Waiting for Feedback  (was: Waiting for Feedback)

I didn't check the original specification.

I tried to make a phone ring and didn't succeed. When investigating, I found that it rejected the call with cause 64 "Invalid information element contents". Trying with a PBX gave the same result.
I would also have expected that an empty CDPN would be the same as the IE missing, but the HTML version of Q.931 I usually consult does indeed not mark octet 4 as optional. So that seemed to fit.

But for reference, with 1TR67 an empty CDPN will not be sent to the user (§3.1.16 e).

>    Affects Versions: 1.4.13
>         Environment: An ISDN interface in NT mode

>            Severity: Minor
>
> 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 /.
