[asterisk-users] callback and bridge problem

Hi guys,

sorry for the long e-mail, i'm only trying to give as much information
as i think is relevant to my problem (console log, sip.conf and
extension.conf parts).  I've sent this e-mail a couple of days ago, but 
it bounced back today.

i've been practicing with callback for a while, but i'm at a dead end.
I hope somebody can help me to move on.

i have troubles getting two calls bridged together.  Scenario is the
following:

- asterisk calls my cell via a SIP provider called neophone
- my cell rings, i pick up, and i find myself in:

[internal]
; callback is directed here
exten => s,1,WaitExten,50
include => voicemail-context
include => internal_extensions-context
include => dialout_prefix-context


because my call file looks like this:

Channel: SIP/06202222222 at neophonex
Context: internal
Extension: s
Priority: 1

where 06202222222 is my cell.

- after picking up, i dial 95206301111111 where 952 is the dialing
prefix, 06301111... is another cell.  952 is a prefix for another
registered account at the same provider (one account is allowed to place
one call at a time).

After this as you can see, the second number (1111..) is dialed.
However when i pick up the phone, the call hangs up.

This also happens when i use another prefix (another provider, even
PSTN) for the second call too.

The relevant part from asterisk console is at the end of this e-mail, i
don't really understand the warning messages.

----- configs:

In sip.conf, the configuration for the two SIP accounts are:

register => 0621380....:password at sip.neophonex.hu
register => 0621381....:password at sip.neophonex.hu

[neophonex]
type=friend
host=sip.neophonex.hu
context=dialout_prefix-context
username=0621380....
authname=0621380....
fromuser=0621380....
secret=password
callerid=0621380....
fromdomain=sip.neophonex.hu
disallow=all
allow=alaw
allow=g723
dtmfmode=inband
nat=no

[neophonex-out]
type=friend
host=sip.neophonex.hu
context=dialout_prefix-context
username=0621381....
authname=0621381....
fromuser=0621381....
secret=password
callerid=0621381....
fromdomain=sip.neophonex.hu
disallow=all
allow=alaw
allow=g723
dtmfmode=inband
nat=no


extension.conf:

exten => _952.,1,Playback(kapcsolas,noanswer)
exten => _952.,n,Set(CALLERID(name)=0621380....)
exten => _952.,n,Dial(SIP/${EXTEN:3}@neophonex-out)

I have tried every possible setting i know about, but still, when i call
outside, via 'turning around' in asterisk, both cells hung up when
answering the call.  I have tried calling a regular landline phone
number but still hanging up.

Both accounts are valid, registered and have enough credit to dial
outside its voice network.

The only way the call does not hung up is when i dial extensions within
asterisk.

The asterisk log:

Please help me to figure out why the calls are hung up.

Thanks
Adam
