[asterisk-users] connect problem unless when verbose

[randall]

hi all,

just had a terrible and sleepless weekend at the office trying to get 
asterisk going, its just tough love ;)

have tried several asterisk versions but i currently have the following 
setup on debian lenny that kind of works.
asterisk-1.6.2.0
dahdi-linux-complete-2.2.0.2+2.2.0
libpri-1.4.10.2
freepbx-2.6.0

setting up the sip devices is no problem at all, the difficulty i have 
is setting up 6xisdn2 lines with 2xb410p cards.

besides the fact that i have no clue about what i'm doing i find the 
available documentation very very confusing, but i finally managed to 
make outgoing calls to my mobile this morning, sort off.

when calling my mobile i hear a ringtone on my sip device and my mobile 
actually rings, YEAH!!!
however, when i accept the call on my mobile my sip device keeps on 
ringing and my mobile gives no sound at all, when cancelling the call it 
simply cancels.

except, and this i don't understand, i issue asterisk -rv (only with the 
v option), then i can connect and talk to myself, i often talk to myself 
when i spent a weekend at the office but this time its justifiable ;)

anybody has a clue what could trigger this behavior???
