[Asterisk-Users] asterisk still tries native bridging

[Igor Zamocky]

  Hello,

  I've problems with following -

  -----                 ---                     ---
  PSTN |  --- isdn --- | A | ----- iax2 ------ | B |
  -----                 ---                     ---

   On [B], there is unconditional call forwarding set back via [A]
   (dialparties.agi is used) to PSTN.
   So, call from PSTN is routed via [A] to [B] and than back again into
   PSTN.
   
   Everything looks good, but, after call is answered, B performs native
   bridging attempt and tries to step out of voice path. And that's bad.
   Because of CDR's collected from [B].

   On [B] and also on [A] there is "notransfer=yes" in [general] section and
   also in [peer/friend] definition.
   It probably doesn't work. I tried to use different iax2 peer for [B]->[A]
   call, so native bridging cannot occur. Fine, native bridging will fail,
   but Asterisk still writes CDR.

   Below is part of [B]'s config, and part of log:

[general]
bindport = 4569
bindaddr = x.x.x.x
disallow=all
allow=alaw
notransfer=yes
jitterbuffer=yes

; ---
register=sip1:QQQQQQQQQQ at y.y.y.y  ; y.y.y.y is [A]'s ip address
; ---
[peerA]
username=sip1
type=friend
secret=QQQQQQQQQ
host=y.y.y.y
context=from-pstn
tos=0x84
notransfer=yes
jitterbuffer=yes

[peerAX]
username=sip1
type=peer                         ; I tried "friend" also
secret=QQQQQQQQQQ
host=y.y.y.y
context=from-pstn
tos=0x84
disallow=all
allow=ulaw
notransfer=yes
jitterbuffer=yes   

So, incoming call comes via "peerA" (alaw), outgoing is made via "peerAX"
(ulaw).

Asterisk stored CDR, but call continued :-(.

Do You have any suggestion what I'm doing wrong?

I'm using Asterisk v. 1.0.9 and it's almost impossible to upgrade to 1.2.x right now.

Thanks a lot

Igor
