Hullo all, I have successfully setup dahdi + libss7 + asterisk and call traffic seems normal. There is just 2 issues I need help resolving: 1. I get the following warning on asterisk cli very often: "unable to forward voice or dtmf". What does this message mean? How do I fix it 2. I should have 2 signalling links each on the 1st channel of the 1st and 2nd E1. The telco sees only one link up and ss7 show linkset 1 only show one link. How do I configure/enable the other? Thanks, Joseph Key Information: Asterisk 1.6.2.9 libss7 version: 1.0.2 DAHDI Version: 2.3.0.1 Echo Canceller: MG2 /etc/dahdi/system.conf # Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER) span=1,1,0,ccs,hdb3,crc4 bchan=2-31 mtp2=1 echocanceller=mg2,2-31 # Span 2: TE4/0/2 "T4XXP (PCI) Card 0 Span 2" span=2,2,0,ccs,hdb3,crc4 bchan=33-62 mtp2=32 echocanceller=mg2,33-62 # Span 3: TE4/0/3 "T4XXP (PCI) Card 0 Span 3" span=3,3,0,ccs,hdb3,crc4 bchan=63-93 echocanceller=mg2,63-93 # Span 4: TE4/0/4 "T4XXP (PCI) Card 0 Span 4" span=4,4,0,ccs,hdb3,crc4 bchan=94-124 echocanceller=mg2,94-124 # Global data loadzone = us defaultzone = us /etc/asterisk/chan_dahdi.conf [channels] linkset=1 group=1 signalling = ss7 ss7type = itu ss7_calling_nai=dynamic callerid=asreceived usecallerid=yes hidecallerid=no usecallingpres=yes callwaitingcallerid=yes threewaycalling=yes canpark=yes cancallforward=yes callreturn=yes echocancel=yes echocancelwhenbridged=yes relaxdtmf=yes rxgain=0.0 txgain=0.0 useincomingcalleridondahditransfer=yes pointcode = xxxx adjpointcode = xxxx defaultdpc = xxxx networkindicator=national_spare ; First signalling channel ;sigchan = 1 ;sigchan = 32 ; First E1 cicbeginswith = 2 sigchan = 1 channel = 2-31 ; Second E1 cicbeginswith = 33 sigchan = 32 channel = 33-62 ; Third E1 cicbeginswith = 65 channel = 63-93 ; Fourth E1 cicbeginswith = 97 channel = 94-124
