Hi,

I have problem connecting Sangoma A101 with asterisk-1.2.10 supporting 
MFC/R2 signalling. The incoming calls is received but this messages 
written in /var/log/asterisk/mesages.localhost.localdomain. (My 
asterisk-1.2.10 came from latest version of ScopServ 
http://www.scopserv.com)

Hi,
Thanks a lot, guys! The problem is now fixed by updating the 
libmfcr2-0.0.3 to pre9 and setting
the span timing correctly.

The libs version used:

1. libmfcr2-0.0.3
2. spandsp-0.0.2-1005_pre25
3. libsupertone-0.0.2
4. libunicall-0.0.3pre??? ---> I'm sure which pre version but according 
to Steve post:

Hi Dennis,
