Description: Can we please have country support for Turkey, (TR, +90), added into the next zaptel package release?

zonedata.c does not contain any ITU E.180 recommendations for turkey, i've added these and recompiled as found from (http://www.voip-info.org/wiki/view/Asterisk+indications+Turkey ), reloaded, however, we are still experiencing unrecognized hangups from Turk Telekom PSTN lines when callers hangup.

Turk Telekom does *not* provide supervised disconnects on analog PSTN, and the tone we receive we when caller hangs up is similar to busy, with three short beeps, followed by one long beep, which keeps repeating. We've tried busydetect, polarityswitch, etc. with no success. Callerid does *not* work either, and it might be related to this issue.

As it stands, asterisk using zaptel (wctdm, with Digium TDM400p) does not work in Turkey. Can offer small bounty for any developer wishing to solve this issue, also for callerid.

As seen in #asterisk-dev:

<puzzled> yarrix: the info about turkish tones can be found in this doc: http://www.itu.int/ITU-T/inr/forms/files/tones-0203.pdf

msahinbas: I think it may help if you could provide an email or whatever for off-line contact.

The entry from there:

Sorry, if you need to contact me about that bounty, please send email to:

msahinbas@fibro.com.tr

I've also attached a paper by Turk Telekom that supposedly describes their network specifications, it is in english. Please see the attachments.

Thanks in advance.

Do you have a configuration that works for you?

Can you post it here?

Asterisk version => 1.2.13
Zaptel Driver version => 1.2.21
System OS => Debian Etch (4.0)
Hardware => X100p Voxzone FXO
Line => POTS

Note : Zaptel is compiled with Turkish indications support.

Hi,

I dont see any feedback for this problem, may the bug reporter give a feedback related with hang-up problem, cos this problem continues.

The problem is below,

When an internal caller calls outside, it seems established but there is no establishment in reality. If i unplug and replug PSTN (rj11) cable, caller can call outside with success, but if caller wants to disconnect called party foreign phone still rings.

For another call, user must replug the PSTN cable.

Changing to 'feature', since support for an additional country is not a blocking issue.

Any word on how to move this issue forward? Do we still have interest in this?
By: Giray Devlet (giray) 2009-02-06 01:02:21.000-0600

Hi All ... we are very interested in this ... our lines constantly stay in a "Offhook" state, with the only solution to restart everything.

I've assigned the issue to sruffell to see if there is something he wants to do with it, but since this is considered a feature, this issue is lower priority than maybe some pressing issues sruffell has on his plate.

Thanks!

I'm going to go ahead and add the tones to zonedata.c.

However, better support for recognizing the tones that we receive on hangup is not something that I can do. Asterisk has poor support for call progress tone detection in general. Improving it, and adding support for detecting these tones, is something that would be _very_ welcome. However, until someone writes the code, we're stuck with what we've got. I won't leave this issue open for that since we do not keep open feature requests without a patch on the bug tracker.
