[Asterisk-Users] Panasonic PBX -to- Sirrix BRI: Numbers gettingechoed/duplicated

[David Wilson]

Hi Peter,

Thanks for your reply.

>indications (out of band) and as dtmf....
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
