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
