[Asterisk-Users] Audiocodes FXO - loop channels

[Daniel Cubero Salas, Ing]

Hi all..!!

We have a trouble with asterisk 0.4.0 and audiocodes MP-108 FXO.

For someone reason some times one extension dial a number which is a PSTN
call (use audiocodes for outcalling but incalling case audiocodes send this
call to one extensions in asterisk like IVR), when that call was finished
audiocodes don´t release the call and line FXO port but send a request for
that phone number (the outcalling contest is different from incalling
contest) then asterisk take that number and request to audiocodes a
outcalling with that phone number, who use a other FXO port... and then a
loop is showed, the worst is never release that 2 FXO ports... I don´t sure
that audiocodes is whom send first request... but that stuff is random

Above a brief report from CLI using show channels:

  Channel  (Context    Extension    Pri )   State Appl.         Data
SIP/audiocodes-875b  (sip_out                 1   )      Up Bridged Call 
SIP/audiocodes-78cb
SIP/audiocodes-78cb  (sip        2XXXXXX      6   )      Up Dial         
SIP/2XXXXX at audiocodes|300|Tr
2 active channel(s)

"XXXXX" is a random phone number 

Where is the mistake? Can anyone help us?

Sorry for my broken english :)

Regards

Daniel
