I am looking for an inexpensive ATA that can assign both analog ports to the same registration that is known to work with Broadvoice. One option that looks like it will work is the ZyXel P-2002, but I haven't seen any confirmation that this will work. I tried a Linksys/Sipura SPA-2002, but to my ignorant dismay, each line MUST have its own registration (as far as I can figure anyway).
Basically I am looking for something <$200, but am uncertain about the cheaper Mediatrix boxes, for example. Has anyone else done this. I have moved into a new site where someone else will manage the pbx and my only way to support VoIP is using analog trunk ports on the new PBX. I'd hate to have to continue to operate an asterisk installation just to provide a couple fxs ports to the PBX, and I'd also hate to tell my boss we have to spend $600
.
I have heard of a 4-port Soyo device, but the (low) cost sorta scares me - if anyone has gotten this working comfortably with Broadvoice, I'd love to hear about it.
Thanks,
Bill
2-FXS ATA compatible with Broadvoice w/ both lines on 1 reg.
