Re: [Asterisk-Users] Repeated Notice: (UN/REACHABLE)
Should this actually attempt more than a single ping before claiming the remote is unreachable? ie, one packet (out of the two - one request + one reply) might be lost or intermittent congestion might be involved. Perhaps a config option for setting number of consecutive ping requests are un-responsive. Also, subsequent requests might be sooner than otherwise queued. ie, successfully answered probes are re-sent every 60 seconds, while after an un-successful probe, we re-send the next probe in 10 seconds Just my 0.02c worth On Wed, 2004-04-21 at 15:03, Robert Hajime Lanning wrote: When you have qualify=yes or some number, then asterisk will poke at the peer, to measure latency.

Must be a misconfig on the switch (Cisco Cat 4500 with all copper 10/100/1000 ports ) cause the switch load was minimal, but somehow the multicast traffic was screwing with the SIP transmission over the wire. Just something for other people to look for. -sb ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

You do have to remember that the RTP session (when you make a call) does not try to recover. So, usually when the SIP poke fails, the RTP would be of bad quality. quote who=Bisker, Scott (7805) On a somewhat related note.

Just something for other people to look for. You would need to configure the switch for IGMP snooping and the ghost clients need to send multicast group membership requests, that the switch will be able to snoop. Otherwise multicast traffic is broadcast to every active port. So, it is not the switch that is being overrun, it is your SIP endpoints, that are flooded with the ghost traffic. -- END OF LINE -MCP ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
