Done with spanconfig! dahdi: Registered tone zone 0 (United States / North America) About to enter startup! TE4XXP: Span 1 configured for CCS/HDB3 SPAN 1: Primary Sync Source 2G: Got interrupt, status = 0000000b, CIS = 0081 Reg 5 is 00000000 VPM400: Not Present VPM450: Not Present VPM450 is not installed. But this * was running calls successfully on ISDN before. So, audio issue is since we have configured SS7 and i think it is related to some parameter on ss7 config. Also, I have completly disabled echocancellation in system.conf(#echocanceller=mg2,1-15,17-31) and related parameter in chan_dahdi.conf. Still i can't hear audio. --- Kind Regards, Deepika Nijhawan VoIP Engineer Oxygen8 Communications T: +44(0) 871 434 9151 +44(0) 121 620 9151 Email: deepika.nijhawan at oxygen8.com Skype: deepika-nijhawan W: <http://www.oxygen8.com/> www.oxygen8.com This communication contains information which is confidential and may also be privileged.
