How can you caculate the number of call an SS7 channel can handle ?. I have a E1 line, can I just need use 1 channel for SS7 signal, and other 29 channels for data tranmission ?. Is it OK.

Using redundant 56k data channels, we handle calls via 6 DS3s (672 X 6 calls) from the PSTN on a commercial telephone switch, with no issues at all. SS7 can support any number of simultaneous calls depending only on the bandwidth of the SS7 channels. SS7 is always done on a redundant channel basis since it is so important.

Can a open source solution such as chan_ss7 or libss7 support many conncurrent calls (for example 240 calls) ?

You must have an SS7 network connection before anything will work. Then the T1 Spans run 24 64k audio paths. The SS7 net exchanges the call data and connection info between the switches. Asterisk doesn’t support SS7 natively although I believe there are one or more add-on vendors.

I've deployed Asterisk before using ISDN connection, but never with SS7. Can anyone explain me the different between using ISDN and SS7 ? What need I do now to change to use SS7 ?. Many thanks, Giang
