[Freeswitch-users] High density freeswitch potential deployment using Sangoma 16 x E1 TDM cards (A116DE)

[Stephen Wilde]

Hi, I don't know if my experience will be useful but we have a running
installation with 5 x A108E Sangoma Boards for a total of 40 E1 (1200 TDM
channels) and it works fine with any issue. We do a mix of IVR and ISDN-SIP
bridging. Our server is old (HP DL380 with two xeon 5520 and 16Gb ram) so a
couple of new CPUs (for example xeon E5-2650V2) will handle your load for
sure.
