I am running 1.4 svn-r95946 and have an error
-- Got SIP response 489 "Bad event" back from 1.2.3.4
The problem is that this error is being generated by Asterisk trying to send a
NOTIFY to a phone behind a NAT firewall that does not exist anymore. The phone
was physically decommissioned 3 weeks ago and 4 restarts ago (couple versions
up on Asterisk during that time), but is still configured in real-time
sippeers. We intend to bring this extension back so we have not removed it
from sippeers, but there is no hardware today to connect using it.
The old phone:address:port was 5003:192.168.168.77:5060 and the firewall is
showing that this address is being translated to address
5004:192.168.168.75:5060.
So I assumed that Asterisk still had a subscription but it does not show up in
sip show subscriptions at all.
SIP debug shows that Asterisk is generating this packet, but I cannot find out
how to remove it. I assume this is stuck in the astdb.
I found Bug 7608 but the version of Grandstream does not seem to make a
difference. Why is Asterisk keep sending out these NOTIFY messages on a
non-subscribed phone? I do not believe the Grandstream phones are wrong in the
489 message, because 5003 is not that phone.
Should I have the 7608 bug reopened, should I create a new bug? Or is there
something I should be changing on my Asterisk server?
Here is "sip set debug 1.2.3.4":
