[Kamailio-Users] OpenSER ActiveWatcher Table

[George Lee]

Hi Expert,

When a SUBSCRIBE message is received, OpenSER creates an entries in
the ActiveWatcher table. This is used to generate NOTIFY message to
watchers. The problem I have seen is that OpenSER keeps on creating
new entries to the ActiveWatchers if the SIP UA deregister, register,
deregister, register, etc. for several times. This triggers multiple
NOTIFY messages to be sent to watchers. How does OpenSER remove
entries in the ActiveWatcher table? It deosn't look like a SUBSCRIBE
with expires=0 would delete an entry in the table.

Thanks,
George
