The right way to VOIP?

[JediBMC]

I am working on a hot project that will provide services to a new remote office. The proposed solution, thus far, has been to put an IP Office into the remote location, then connect it via T1 to our Definity G3si. The remote office will have 8 people initially, but I am planning for 20, as things tend to expand here.

In looking at the abilities of our G3si, I am wondering if we really need to go with a completely seperate IP Office switch. Since our G3si has two CLAN cards (TN799DP) and our software is in R11, could I just install a MedPro (TN2302AP), buy the appropriate number of RTU licenses, and run the IP phones across the T1?

Perhaps I am not properly understanding things here, if so, please show me the error of my ways. I am still VERY new to the telecom and Avaya world.

Thanks!

Yes, you could simply run IP Phones across the T1 alone.
But you won't have any local lines that those phones can access - either in or out dialing. You'll also have to finagle with 911, as a 911 call would hop out of your Definity.

With a local gateway (G350, G700, or G150) you'll get local trunks as well as survivability (with an s8300 in the case of the 350 and 700)

With a remotely trunked ip office, that system will need to be admin'd separarately as well as voicemail will need to be dealt with. The advantage to that would be no need to buy more RTU's. For voicemail you could either use the fallback to Audix option or have a local voicemail server for each system...
