I have two call manager 3.0.9 systems for redundancy. Sometimes(about 1 week),the message "Not enough bandwidth" will be display on Screen (7960) .

if make a call via WAN (F/R 192k) .

But when we switch to another call mamager system ,

Everything will be Ok .

Re: Error message "Not Enough Bandwidth" .

When you say “two call manager 3.0.9 systems for redundancy” and “A distributed System of two sites” which do you mean? Are you clustering (I hope not)? Do you just have two call managers that just see each other as H.323 gateways? Are you using a Gatekeeper?

In a distributed design the role of Call Admission Control is best assigned to the Gatekeeper.

Re: Error message "Not Enough Bandwidth" .

Thanks for replay.Sorry for my carelessness . Each site has two Call mamagers for redundancy.We don't

have any call admission controller(Gatekeeper) between two sites.

The problem is : "Not enough bandwidth".That's not

a really problem .Just showed on screen and means can't communication via wan. (even just one call)

But function will be fixed after restart system or switch to another system (secondary call mamager).

I think that system will be locked after something happened .
