[cisco-voip] Connectivity problem with remote site

[Ryan Ratliff]

If you have QoS enabled at each end of the VPN are you seeing drops in the voice signaling queue(s)?

I forgot to add:

VPN uptime counter is at 6days and change.

Have several line of business applications that are running thru Citrix that are not being affected.
Nobody is noticing any drops in connectivity (I know that VoIP is very sensitive)

I would first check the VPN for issues.  You should be able to check uptime on the VPN connection, if that is staying low, and therefore interrupting communication with UCM, that would cause those problems.  Could be an issue with the provider connecting the sites.

Starting last week, I've had one of my site go a little bit looney.  Dropping calls, Phones saying UCM down, Pushing the extension, getting dialtone, dialing, and having a live call already on the line.

 
It looks like a connectivity issue, but I can't figure out what's going on.   The site has been up for about 13 months with no issues..  Nothing has changed in the network.

 
I'm pinging a bunch of the phones.  They haven't dropped any packets, and all my pings are 2ms or less.

 
here's what's on the phone Display log:

 12:29:06p 23: Name=SEP00235E18F284 Load= SCCP41.8-5-3S Last=Reset-Restart 

 
 
I've been pinging the phones since 12:00, so I've had at least 3 "events" while I've been pinging it.

 
UCM-closed-TCP indicates that a firewall closed the connection.

I have a L2L vpn between sites:

CUCM -> 6509 -> ASA5550 ===IPSEC===> ASA5505 -> Switch -> Phone

 
Where can I look for more information to diagnose what's going on?

 
Mike
