[Asterisk-Users] E1 Disconnection Asterisk behind an old PBX

[Marco Mouta]

Hi all,

My scenario is this one:

LandLine------------------E1---------------|-------------|
|-------------------|

|OLDPBX|-------E1-----------|Asterisk1.2.5|-----VoIPusers
GSMGateway---------Analogue------ |-------------|
|-------------------|



What is happening:

1- SipUserAgent "A" Dials a call to a Local Extension "B" in the OldPbx
2- "B" , the called party decides to Hangup the call
3- Asterisks detects this disconnection and hangsup the call

1- SipUserAgent "A" Dials a call to a Mobile or PSTN phone "B"
2- "B" , the called party decides to Hangup the call
3- SipUSer Agent "A" just starts listenning the busy tone indications and
Asterisk doesn't hangsup the call automatically.
4- The call only gets finished when the Sip User Agent "A" hangs the call on
the SIP phone.
5- This way asterisk CDR could be reporting 30 minutes call duration , even
if i have 1 minute of speech and 29 minutes of busytone indications....

Could be the OldPBX that doesn't send the disconnect ?

Any tips?

Best regards,
Marco Mouta
