2 office locations - 1 system

2 office locations - 1 system

2 office locations - 1 system

Y'all forgive me if this is too much of a newb question, but I have no idea where to start. I have a request for one of our newly acquired clinics that has two locations about 12 miles apart. We have our network in both spots via fiber, plenty of bandwidth. I need to know what to ask my vendor! The need is for 53 phones total, divided about 3/4 to 1/4. I want to use 96xx phone sets. They get a SIP connection from AT&T for the outside world at one location, and the second uses that connection through the network. They want to keep their 4 digit intercom dialing. I know I will need a chassis with at least a combo card at the remote end for a fax line (POTS) to either use as a fail-over for 911 or to add POTS back-up for the same reason. There is also a POTS fax line at the main location for a fax, and I figure a combo card there will serve the same purpose. Basically this will be a large office system with 2 buildings tied together. I have used the IP Office with 96xx phones in a single location, but this one is new.
My experience so far (20 systems) is single building, all POTS, and all but one using 95xx phones. This will be a bid jump for us. I am starting my thinking with one chassis at each location, one VCM 32 card and one combo card each, and a butt load of licensing. Any help with how to explain this to my vendor will be GREATLY appreciated. Thanks in advance!
**EDIT** forgot to say that the POE switches are already in place, programmed/ managed by us in-house. Any VLAN recommendations will be appreciated as well.

RE: 2 office locations - 1 system

If you only gonna have SIP trunks on one location there is no need for 2 IP500s, just treat it as a single site system and connect the IP phones on the remote site to the same system.

RE: 2 office locations - 1 system

Janni is correct but it is worth considering what happens to the remote site should the data connection between sites fail?

a 2nd system & a fallback line is worth considering (if only for health & safety compliance)

Do things on the cheap & it will cost you dear

RE: 2 office locations - 1 system

Thanks, Janni and IPGuru. I was thinking both ways, and also just having the second system for that purpose. Even if it is just a stand alone, they would have an emergency phone.

RE: 2 office locations - 1 system

You need to think about 911.
Are you in a state that requires E911.
Can you service provider support 911 from the remote building?
Fiber can get cut. Do you need backup?

RE: 2 office locations - 1 system

Yes, we require it, and being a medical clinic, it is doubly so. That's why I am wanting to do the second unit. The Fax line is there already, should be able to get another POTS TO at least give them 2 lines at the remote for fail over. But if I am thinking correctly, they can be independent systems if I place a digital set at the receptionist to use in that case, correct?
