What is the application for 160 FXS ports? Are you hooking up a hotel or something? I would think the application would determine what level of HA you need. In some cases having a warm standby on site would be sufficient. In the case of a failure of box 1 you could have someone go to the switch room and fire up box 2. This works in cases where a minute or two of downtime would be inconvenient but not a show-stopper.

Hi,

Happy New Year!

What would you recommend for a solution that requires ~160 fxs ports?
Should I get a Sangoma A200, in fact 7 of them and put them on to my
server or look for other products like Audiocodes/Patton fxs gateways
etc?
If I choose Sangoma cards, then I don't think I can set up a HA
scenario since, all fxs ports will be on the FS box itself.
But from what I've read people have horrible things to say about most
gateway devices. They are prone to failure and the support is also
very lax.
So what good would be HA anyway, if one of these gateways fails and
knocks 32 fxs ports off!
Also I see that Sangoma is actively involved with the FreeSwitch
project and digging through the mailing lists, I could see great
support as well.
Is it advisable to have 6-7 cards with 12 fxs modules each on my FS server?

Any suggestions/pointers/heads-up would be really appreciated.

Thanks
guru
