Error calls towards trunk SIP

[11.30.40] Ursula: Hello,
The problem is very simple. I have always used the two trunk sip on my asterisk 1.6. Usually I use them for a demo with clients, and in order to activate them on development machines. Since yesterday they doesn’t work anymore.
If in CLI I write SIP show peers, I see them correctly as UP, but if I try to call by using them I see the following message:
Error calls towards trunk SIP

Executing [XXXXXXXX@from-pstn:1] Dial(“DAHDI/9-1”, “SIP/lh01/802”) in new stack
== Using SIP RTP CoS mark 5
== Using SIP VRTP CoS mark 6
– Couldn’t call lh01/802
== Everyone is busy/congested at this time (0:0/0/0)
– Executing [XXXXXXXXX@from-pstn:2] Hangup(“DAHDI/9-1”, “”) in new stack
== Spawn extension (from-pstn, XXXXXXXXX2, 2) exited non-zero on ‘DAHDI/9-1’
– Hungup ‘DAHDI/9-1’

lh01 is trunk name
802 is the internal
XXXX are for privacy

Of course I rebooted the machine several times and I have not made ​​any installation and / or updates for at least 6 months

Does anyone have any ideas?

greetings
David

No codecs, presumably because of the disallow after the allow.

Also, 60 seconds is rather short for a re-register interval, and it is possible that they other side might not go that low.

thank’s for reply…but i don’t understund ho to solve it…

must I commit disallow=all?

Where Can I increase the expiration time?

I solved it!!!

I’ve change disallow=all before allow=g729,alaw,ulaw,g723,h263,gsm

Thank’s at all

Now remain how to increase the expiration time

The short register timeout may actually be set at the other end.

try adding
register=300
to the sip.conf entry. it is presently not specified so the default is 60.

The default may be OK. It just felt a bit aggressive to me. I would leave it alone if it is working now.
