[asterisk-users] Official Documentation for Asterisk 1.6 Realtime ODBC Tables

More information: When I have "rtcachefriends = yes" in sip.conf, everything seems fine. With "rtcachefriends = no" I see this behavior. 

I'd rather not cache. I'm aiming for as near real-time as possible. 

Any thoughts?

Hi Brad, 

I did notice that bug in the bug tracker. That's different from the behavior I am seeing. I don't get multiple values in the "Mailbox". I just upgraded to 1.6.2.14 and it's still there. 

By the way, the quantity of SIP NOTIFY's generated is significant. It appears to be way more that the number of peers I have (3) times a handful of duplicates per peer. I've been doing a Wireshark capture, and it appears as though any time there is a new message in the ODBC voicemail store for a mailbox that has been subscribed to, Asterisk continually generates as many of the messages as possible. At one point I noticed my CPU jump from 0% to ~50% just by moving one message from an mailbox that hadn't been subscribed to to a mailbox that was subscribed to by the 3 peers. It only came back to ~0-1% by moving the message back to an unsubscribed user. 

When I set rtcachefriends = yes in sip.conf, I get the following for each peer: 

ast01*CLI> sip show peer 412

I agree with Paul, this sounds like a bugs that's been fixed. 

What does the 'Mailbox :' line look like when you do a 'sip show peers'? 

My guess is that there will be multiple entries of the same mailbox, and 
that's why you're receiving a bunch of NOTIFY messages.
