Faxes, are... maybe's. We at home send faxed over our VoIP line (it's not business critical, and it's "free" so we do it).
I do believe that their are VoIP solutions that you can send LD over the VoIP and local over land lines. Which might be a better option. Unfortunately I am not a VoIP PBX expert, and have limited professional VoIP experience outside the 9-1-1 world. |
That's kinda what I was pointing to, lots of hardware can do that, the work is programming/maintaining the rules and routes for each class of call.
I knew Faxes in and out are the life blood of a law office right after client calls and billable hours and there are commercial IP solutions (not via the VoIP) for fax's, leave the data as data, the only consideration is allowing adequate bandwidth for quality voice and sorting/routing calls either to the local PSTN network or out as VoIP.
Is the T-1 the only internet/broadband option?
Is there a reason outside phone calls need to be passed via the t-1 and the other office?
Is a majority of the voice traffic between the 2 offices?
ie A good PBX should be able to route office to office calls via the T-1, other outside/LD calls via a local broadband link, and local/911 calls to the local pstn automatically (according to programmed rules) and failover as directed(more rules) even selective forwarding.
a couple consideration are voiced here
VoIP Systems Increase Network Support Burdens
Voice-over-IP systems are proving to be more complex to manage and support than many IT managers expected, a development that is driving increased demand for outside support services.

and having a third party responsible for planning, installation and maintainance may be more cost effective.
