[asterisk-dev] strange outbound-registration loop

[Klaus Darilion]

Hi!

Yesterday I had a strange issue on an Asterisk 1.4.26.1:

[Aug 17 20:06:20] NOTICE[14509]: chan_sip.c:7829 sip_reg_timeout:
-- Registration for '1234567 at sipgate.at' timed out, trying again

These were at least more than 500 retries within 1 second. Unfortunately 
I do not have a SIP trace, but I suspect that there were no messages 
even sent - it looks like the sendto() function failed with "Invalid
argument" and Asterisk tries to reregister immediately. Maybe some 
timeout should be added in such a case?
