Periodic 484 Address Incomplete when system is idle

Hi all,

I’ve been using Asterisk 1.4 and now I’ve upgraded to 1.8. My box is behind a firewall and connecting to Draytel’s SIP service (draytel.org).

All is well apart from a couple of problems which I need some help with.

  1. If I switch on the sip debug (sip set debug peer draytel) I get periodic 484 Address Incomplete every minute or so. It seems to be with the re-registrations to Draytel. Nothing else is happening on the system at the time and I don’t see this when we make any calls on SIP extensions. This is the part of the SIP debug that I’m referring to:

Again, this is happening when the system is idle and happens approximately every minute. Perhaps it’s nothing to worry abou?

  1. I don’t know whether this is related, but occasionally the connection to Draytel becomes ‘unreachable’ in ‘sip show peers’.

draytel/ 217.14.132.183 N 5060 OK (199 ms)

vs

draytel/ 217.14.132.183 N 5060 UNREACHABLE

When this happens I can ping 217.14.132.183 and I have not yet found out exactly what to do to recover it. However, yesterday it was ‘UNREACHABLE’ for 24 hours and I think it may have cleared when I switched my firewall off then on again. I’m looking into this as a possibility but I would appreciate anyone’s thoughts and comments on this one. This seems to have started with Asterisk 1.8.

Thank you in advance.

Craig.
