Can anyone point me to a list or document that describes the various telephony protocols that Asterisk supports? I’m curious as to whether it supports TUP and CAS.
I’m running a TE420 with Asterisk 1.6 and DAHDI 2.3.0.1 with libss7 and have successfully set-up SS7. Thanks in advance!
Howdy,
While libss7 does provide ISUP support, it does not provide TUP support.
If you’re an apt coder, contributions are welcome. 
Cheers.
Hi,
Chan_ss7 can support ISUP and we have provided TUP added to it.
If you are interesting, we chat by MSN or email.
