I have seen this issue where there were internet connectivity issues. Asterisk
registers every so often with the ITS. For some reason or another (it can be
many reasons such as DNS, internet, ISP has issue etc). asterisk cant
re-register so it keeps trying.
As far as the so context if you have a simple register line in sip.conf (such
as register=> axe:[EMAIL PROTECTED]) then asterisk will tell the server that it
is registering it with to send all calls to the s extension in your default
context.

Subject: [asterisk-users] SIP registration problem
I've reposted with a more meaningful subject - hopefully someone will
reply....We have an Asterisk v1.2.16 box registering with an ITSP using SIP.
The registration succeeds, and is confirmed with SIP SHOW REGISTER. However,
we frequently (every few minutes) see this on our console:
REGISTER attempt 1 to [EMAIL PROTECTED]
REGISTER attempt 2 to [EMAIL PROTECTED]
Any ideas what is going on? In particular
1. What causes the two register attempt messages above?
2. Why is our asterisk box being associated with the "entryunauthorized"
context, not the "entryinternal" context? (See below)
3. Why is the contact "<sip:[EMAIL PROTECTED]:5060>" in our SIP messages,
why s@ anything?
Thanks
