I like the ATA + 2500, you will find something like this (usually channel bank -> 2500) in telemarketing centers as it is hard to kill one of those things through general use.
That aside I see older Polycoms like nokia’s. you can probably pickup some old 5xx’s on ebay cheap. I think @reconwireless may have a stash
Just spent the last few days testing the HD aspect of the VVX-300 and VVX-310’s and I can say without any hesitation the sound difference was AMAZING… almost weird it’s so clear and crisp. It made me realize just how BAD cell phone quality is. It also seemed to make otherwise bad phone calls less “fatiguing” if that makes any sense to you. We also test an older Grandstream just not sure what model and we had similar results.
Take all your suggested phones and a good old Bell 2500 set, throw them all at a concrete wall as hard as you can, then get your fat friend to jump on them several times, I’ll take dollars to donut holes on which one is still fully functional
Hi If you can Find some Old or used quintum that’s the solution I’m doing the Busyness’ In Greece 15 years sale Voip solutions to call shops
You can easy set Up and add any Software Billing
And you will never have Issue with the Second Port Codec
Usually the IP phones don’t usage Simulations Both Ports with G 729 and there comes the issue if you customers want do International calls Most from carriers don’t terminate G 711
The solution its you have to Go to Some USA carrier to terminate you calls all G 711 at that with question mark ???
With Quintum you will not have this problems Voice Codec conversion its passable see manuals before you do any Move
