Hi, I am running a SS7 link (libss7-1.0.2, dahdi-linux-2.0.0, asterisk-1.6.0.1) which works fine for voice calls, but I have encountered problems connecting to some fax machines. It seems that these fax machines need an ISDN bearer capability of "0x9090A3 - 3.1 kHz Audio call (A-law)", but the ss7 link always signals "0x8090A3: Voice/Speech call (A-law)". I have tried "Set(CHANNEL(transfercapability)=3K1AUDIO)" but without success. Looking at chan:dahdi.c I could not find a reference to the ast->transfercapability (except for a check with the IS_DIGITAL macro). Is there a way to signal 0x9090A3? regards, Andreas
