I think the T-1 will give him a better network choice, as you wont have to deal with the added latency of MPLS. A simple router can provide adequate QOS for Voice and Data connections, and the cost of a dedicated T-1 from the Teleco in most areas is very affordable these days, especially for Government.

Might I suggest a private MPLS cloud instead of the T1's with tagging for voice... this way he can use VVX's out on the fringe and we all know how fond of those he is.

Patton will require additional routing rules for base functionality b. Additional dialing rules to route between sipxósipxóNECóetc. c. Greatly complicates the overall design 2) Functionality a. End users are expecting the capability to plug their phones in and just work (at any county location) if we are routing DIDs to the remote and they plug their phones in at our Emergency Operations Center it needs to just ring there 3) Costs a. One of the driving factors is reducing costs having a server (granted could be an inexpensive one), plus failover trunks (handful of POTS lines), plus additional analog gatways. We are then looking at $2,000 capital costs and $1,000 annual operating costs. This greatly drives down the ROI and it seems hard to justify those costs coupled with the added complexity of managing separate servers (plus having multiple DNS/DHCP scopes). All to work around a potential 2% business interruption (considering a potential 1 week down time hazard). A HA install could be a compromise, but that introduces its own issues - Perhaps a good compromise of a unified system and failover would be to have a second route between sites; i.e. have a site to site vpn over the internet that would be a backup link. In the event of a T1 failure, we could route traffic over said connection? In a perfect world, Id love to have a single, simple to manage phone system. Not 5 separate systems that I have to link together and have equipment all over the place that I have to keep tabs on. Of course, Id also like to not get fired for killing all of our phones J Nathaniel Watkins IT Director Garrett County Government 203 South 4th Street, Room 210 Oakland, MD 21550 Telephone: 301-334-5001 Fax: 301-334-5021 E-mail: nwatk...@garrettcounty.org From: sipx-users-boun...@list.sipfoundry.org [mailto:sipx-users-boun...@list.sipfoundry.org] On Behalf Of Tony Graziano Sent: Thursday, July 01, 2010 3:01 AM To: maybelater Cc: sipx-users@list.sipfoundry.org Subject: Re: [sipx-users] sipx-users Digest, Vol 76, Issue 154 Nathaniel, It really needs to be an analysis of "how that branch" functions. Depending on the role the branch serves within the organization in the event of any "natural disaster", especially for intra-office communication, relying on a T1 to call down the hall, upstairs, downstairs, etc, is perhaps "nonsensical". A local PSTN gateway for inbound calls to be redirected for a main number, and for emergency outbound calling pretty well insulates it. With forty or so workers, 1 T1 only goes so far when it comes to calls:bandwidth. Of course, for branches with enough users, I always stick with a dedicated system per branch as I like a higher level of functionality when something goes down. For instance, if the T1 goes down and they can no longer make enterprise calls to other branches, they can dial the published number via a "copper rule" for dialing out via PSTN on a local gateway (as well as 911). Ultimately there has to be a "weight" to gauge what needs to be available, and how efficient and connected the branch stays in an outage. With a separate system the users can: 1. Continue t have their phones register. 2. Call each other. 3. Check voicemail. 4. Dial around to call out via alternate gateway (analog/siptrunk). 5. Call from their desk to bug you to ask you why you haven't fixed it yet. 6. Call other branches via their PSTN published number. Calling patterns, roles and survivability are all factors.
