46XX Registered Remotely - Bandwidth Requirement?

[98Converter]

We have a branch office and will be placing a point to point T1 between there and our main site (S8300 CM3.1).

We want to hang (5) 46XX or 96XX off our S8300 2 miles away. We don't want the cost of a G250 Gateway...

We understand the bandwidth requirements for calling, however when the phones are in idle state - what bandwidth requirement to they have? Basically what if any is the 'keep-alive' requirement? 1 Packet every 40 seconds...?

Also what good business case besides survivability could be said for spending $6k for the G250 & S8300?

Thanks,
CJH

IDLE = 55bps

If you had a GW and the WAN goes down you could do 4-digit redirect over the PSTN so your customer do not know the WAN is down. One other thing to think about is 911 calls.

It's definitely good practice to put some PSTN access in your brannch office for emergency calling if your WAN link goes down. A gateway in that office will allow you to fail over to that PSTN link and still be able to place calls.
You could also just put a POTS line or two in there and put a couple big red phones on the walls for emergency use only
