* don't send Q.931 DISCONNECT after Hangup

chipsake · March 31, 2006, 9:39am

Hello

model:
SIP hardphone <-> * PBX <-> ISDN line & analog line

problem:
for outgoing and incomming calls
when SIP hardphone hangup

don’t generate DISCONNECT Q.931 message
i get that message from ISDN network (usually 60-90 sec. - normal provider conf.) but, in that time, calle telephone is locked

PC.conf:
2.6.15.4 i686 GNU/Linux (Debian 3.1)
Junghanns quadBRI ISDN controller: Cologne Chip Designs GmbH: Unknown device 08b4 (rev 01)
Subsystem: Cologne Chip Designs GmbH: Unknown device b520
TDM: Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface
Asterisk 1.2.4
bristuff-0.3.0-PRE-1l
libpri-1.2.2
zaptel-1.2.3

Analog line works fine.

Good people, do You have any solution, clues, sugestions ?
Thanks for any replay.

I have got the same problem. Have you resolved the problem?

Thanks.

What is your SIP hardware phone?
This looks like problem of phone.

I had oposite problems. When I dial landline - hangup worked only from SIP phone side. Problem was with missing reverce polarity of landline

chipsake · April 11, 2006, 1:04pm

the SIP Hardphone id Welltech Lanphone 201.

But Asterisk know to stop the call

13:04:00 channel.c: Didn't get a frame from channel: SIP/XYZ-2743 13:04:00 channel.c: Bridge stops bridging channels SIP/XYZ-2743 and Zap/7-1 13:04:00 channel.c: Hanging up channel 'Zap/7-1'
But quadBRI don’t generate DISCONNECT…
I have no idea, maybe there is some error in drivers ?

Thanks for replay

PS. rrc2 : i didn’t resolve this yet.

bira_more:
thats, what i know, ISDN(Q931) don’t use polarity reversing to generate disconnect. Q931 sends ‘DISCONNECT’ message to Provider PBX (but correct me if i’m wrong)

sure, because ISDN uses DSS1 signalling, a digital packet signalling messages, so no “analog” changing of polarity is needed…

Fdragowski,

[quote]
bchan=1,2
bchan=3
bchan=4,5
dchan=6
bchan=7,8
dchan=9
bchan=10,11
dchan=12[/quote]

is thisline here correct ?

bchan=3

Shouldnt it be a d-channel ?

RichardHH · April 16, 2006, 6:03pm

Im not sure about poland, but did you try changing the framing ?

like
span=1,1,3,ccs,hdb3,crc4

chipsake · April 20, 2006, 12:22pm

bchan=3 - it’s wrong, but i make mistake in copying it here, in config there is dchan=3.

i didn’t try changing the framing.
Now i lost access to this * server, our client cut off my remote access.
I don’t know if i will have a chance to resolve this problem.

Thanks for help.

RichardHH · April 20, 2006, 12:54pm

Well, if your customer cancelled the remoteaccess, he obv. needs no more help, so i wont bother…
