asterisk users - Jul 2005 - Panasonic PBX -to- Sirrix BRI: Numbers getting echoed/duplicated

Hi guys,

How's things going ?

Got a bit of a weird one here that I've been unable to solve.

I have a Panasonic PBX linked to a Sirrix Quad BRI card that is running in TE
(ptp) mode in a Asterisk box - this then links through Internet to another
Asterisk box via IAX2.

When a user on the Panasonic PBX system dials the extension of my Sirrix
Asterisk box, Asterisk answers and says "Please dial the number of the
person you are looking for....". This is done with cmd
"Background".
When this user enters an extension number to call the numbers that get picked up
by Asterisk are repeated/echoed.

For example, if a user enters "19" at the voice prompt, Asterisk picks
it up as "1199" and tries to then dial "1199" out to the
remote Asterisk server.

Any ideas what causes this ?


Kindest regards
David Wilson

One possible cause is that Asterisk receives the digits both as isdn 
indications (out of band) and as dtmf. Are you sure you have answered the 
line? On a bri link audio can be passed even without the line being 
answered.

Before the line is answered Asterisk can receive overlap digits. While 
in overlap reception mode in band (dtmf) digits are ignored. Yuo may want 
to enable overlap digits nn the link to the Panasonic.

I am not familiar with this particular BRI card. If it is not based on 
zaptel then the configuration will have to be made elsewhere.

Hi Peter,

Thanks for your reply.

Good point ! This sounds like it could be the problem.
>Are you sure you have answered the line?
Yes, as far as I know ? In that context I have the following:
[pabx2ip]
exten => s,1,Answer
exten => s,2,Wait(1)
exten => s,3,ResponseTimeout(3)
exten => s,4,Background,enter-ext-of-person
exten => _X.,1,Dial,IAX2/pmb/${EXTEN}
exten => t,1,Hangup
exten => i,1,Goto(s,1)

Should be OK ?
> Before the line is answered Asterisk can receive overlap digits....
Yea, I thought about this and tried "dialtimeout = yes" in 
"/etc/asterisk/sirrix.conf"
ref: 
http://www.voip-info.org/tiki-index.php?page=Asterisk+config+sirrix.conf

I think the problem is probably, as you pointed out, that Asterisk is 
picking up the DTMF stuff as well.
Do you know of a way to disable it ?

Thank you for your help so far - greatly appreciated.


Kindest regards
David Wilson

Yes, it should be ok. At this point Asterisk should have sent an Answer 
message to the pbx and it should have stopped sending digit indications 
in the control channel. 

I am not familiar with the Sirrix cards. Can you get the equivalent of a 
Zaptel "pri intense debug" for the data from that card?

Peter

Hi Peter,

Thanks for your reply.

Would "srx show ccmsgs 1" help ?

I am not familiar with the Sirrix line of BRI cards. However, someone else 
on the list may be, or you may be able to diagnose the problem yourself.

Peter

Thanks Peter.

Any other takers on the list on this one ?

Kindest regards
