Question on losing Network Connectivity

Hi, we are installing new Avaya phone systems in new Branches when we are opening them. At one site we have two G650's and at another we have two G700s for example. I'm not to familiar with the set up but we have them connected to the network to dial internally on our network for free and then have PRIs connected for outside calls. When we have network outages at these new locations we loss dial tone on the Avaya phones set. We thought that we should be still able to dial out on the PRI's when the network is down. Is this normal? Thanks, Jason.
 
G650s and G700s are not "survivable" gateways. You'll need to pair them with a local processor (an ESS. Typically an S8300 server)to take over call processing in the event the gateways cannot see the main system processor.

In the future, be sure to look into LSP type gateways. The G450 is a local survivable gateway option. In the event of a loss of connectivity to the main processor, the G450 will take over call processing on it's own. (after a brief timeout period.)

Carpe dialem! (Seize the line!)
 
I just found out that we do have a S8300 server at each site. I assume there is a setting that wasn't set? Thanks, Jason.
 
Remember that there is a timeout period before the ESS server kicks in. The setting is between 3 and 15 minutes. Type the command:

change system-parameters ess

Check page 7. The "no service timeout" is the amount of time in minutes before a gateway's IPSI will seek the next highest ESS server in it's priority list.

You should expect no service until either the timeout interval or the network outage expires.

S8300 will be better to work as an LSP. Since you have them at most of your sites, just make sure you hav the correct lisence for them. In operation, your individual sites will stand by its own, since they have their own survivable servers (S8300 LSP).They will take control of your phones and the PRIs(assuming you have them on the same gateway)
