[asterisk-users] SIP Dial out timeout

[Arik Raffael Funke]

Hi,

I am having a problem that is a miracle to me: If I dial out via 
voipstunt.com the call rings for a few seconds and then gives me a busy 
sign.

- I do not have a timeout set in my dial command
- the remote station does not cause the busy either
- dialing the number with the voipstunt client does not give busy after 
a few seconds
- dialing with the same voipstunt account with a softphone works without 
problems
- when dialing out via other channels, i.e. iax or misdn on the asterisk 
machine, no "timeout" problem

-in the CLI there is no message at all when the "timeout" occurs. It shows:
...snipp...
     -- Called +4970712976872 at voipstunt
     -- SIP/voipstunt-081b61a8 is making progress passing it to mISDN/1-1
P[ 1] After SETUP BC
funke*CLI>


Given these facts I believe that the problem has something to do with my 
asterisk setup, and more specifically, as it only occurs with SIP, 
sip.conf. Is that reasonable?

Unfortunately I have absolutely no idea, how to narrow it down further.

My sip.conf looks as follows:
----------
[general]
bindport=5060
bindaddr=0.0.0.0
srvlookup=yes
allowguest=no
qualify=no
srvlookup=yes
canreinvite=yes

[voipstunt]
type=friend
host=sip.voipstunt.com
disallow=all
allow=g726
username=my_account
fromuser=my_account
secret=my_password
qualify=2000
canreinvite=no
promiscredir=yes
rtptimeout=300
rtpholdtimeout=300

----------



If anybody has any hint on how this might be solved, please let me know.

Cheers.
Arik
