[Freeswitch-users] FS and TDM

[Anton]

Michael,
Thanks for reply.

Yes, I do use SANGOMA TDM cards in my systems - have several 
types of their TDM and analogue hardware (A200, 
A102,A104,A108,108D)

Right now my most capable system runs latest asterisk with 
20 ports TDM, SS7 and PRI (chan_ss7), though call volume is 
not too big, and it's almost obvious that asterisk won't be 
able to carry the full capacity of 20 ports in the single 
system. Possibly having fresswitch outperforming 
asterisk "by factor of 10" - is the solution which would be 
able to carry the necessary capacity. Unfortunatelly with 
no ss7 support I can't really use freeswitch - but maybe 
PRI will work. Just some doubts that someone in the 
mail-list noted that PRI support is also not so good yet 
too and might not be ready for production. 

Any thoughts of asking makers ("dicea" currently and 
possible "sifira" too) of chan_ss7 to release their channel 
under compatible license too? SS7 becoming the preferable 
protocol for telco connectivity more and more and in my 
country I even can connect to a telco only via SS7.

Sincerely,
Anton.
