[Asterisk-biz] Modem Over IP: solutions ?

[Jean-Michel Hiver]

Hi,

I have a potential client who has legacy alarm systems which use modems 
to transmit encoded data to a remote location through the PSTN. They 
wish to replace the 'PSTN' bit with an IP link.

I am aware that it would be best if the data was transmitted directly 
over IP rather than modulated and then sent on the internet, but that is 
not possible because of the legacy equipment.

I was wondering if there was some specialized ATAs of some kind that 
would do TDMoIP and which could be used for this purpose?

Link latency is about 300ms with no more than 10ms jitter. If you have a 
solution please let me know!

Cheers,
Jean-Michel.
