Megaconference

[Russ Stoup <>]

Hello everyone,

I have 13 units, but am currently only using 5. I have two Polycom VS4000's at one site, two at another and one alone at another site. 

When I start a call in the morning I usually have to restart the systems. They will not connect if I don't. Sometimes it will even ring at the other site and never pick up. Most of the time we get an error of "destination out of service" or sometimes "resources unavailable". When we are having issues I can't see the interface, but when I can, I see these errors on the call detail. 

The destination does not respond to the call so the connection cannot be completed.; Call Manager Call Progress timer has expired. Call progress has not moved to the call completed / connected state.

The destination address is not serviced by the intermediate network through which the call is routed

A signaling message cannot be delivered because the interface is not functioning correctly and therefore the destination cannot be reached. This condition might be temporary though of extended duration; for instance remote equipment might be turned off.

We are attempting IP connections. If I restart all the systems I can make the call. If anyone disconnects, I have to repeat. 

We go through a state network for our bandwidth. They get their lines through Frontier. 

So far neither the network people at the state level or my local level can find out what the issue is. They want to blame hardware, but the thought of 5 units going out at once seems out there.

I did try something today and it worked. It might have just been lucky, but it worked. I am given a bank of IPs to use for my units and the gateway. I changed the IPs. Either the issue was gone today or my changing the IPs worked. 

Does anyone have any ideas?

Thanks,

Russ
