hi Anita, I think the answer differ from telco to telco, but it's in their interest to provide solutions to volum customers. I will recommend you ask for quotes and compare raw SIP, E1''s, E3's and STM-1's. A major question is how do you plan interfacing to the telco? Will you be using Q.931, Q.SIG, SS7 or something else? FreeSWITCH "as is" can't support this card, but it can be made to do so. I assume Sangoma delivers a L1/L2 driver ? In which case I easely can tweak both L2 and L3 to fit. I have to make a few assumtions here because I have no knowledge about how smart Sangoma have been on the PCI interface/driver side of this card.

Hi Please check out this product http://www.sangoma.com/products/hardware_products/data_networking/a301.html Does it work on Freeswitch or Asterisk ? Do Telcos provide an E3 connection ? One of our customers had an inquiry for terminating 6000 calls simultaneously. I want to do some homework before taking it further with him. If I use E1 lines, I will need 6000 / 30 = 200 E1 lines, which does not look feasible ? Thanks for any input you may provide. regards, Anita Hall, Simmortel Voice. _________________________________________________________________ Hotmail: Powerful Free email with security by Microsoft. https://signup.live.com/signup.aspx?id=60969
