[asterisk-users] No Audio on pstn call

[Siti Zalifah Md Yatim]

Hello,

I'm facing problem where as whenever there are incoming call from
pstn, there will be no audio coming in. User at the other end also
could not hear my voice. This happens few days back. Im using asterisk
1.6.1.2 with dahdi tool 2.2.0.

I thought it was time to upgrade, so upgraded to dahdi 2.2.1 and
asterisk 1.6.2.5. However, it does not help at all.

My current config as follows :-

X100P clone card

/etc/dahdi/system.conf
# Span 1: WCFXO/0 "Generic Clone Board 1" (MASTER)
fxsks=1
echocanceller=mg2,1


/etc/asterisk/dahdi-channels.conf
; Span 1: WCFXO/0 "Generic Clone Board 1" (MASTER)
;;; line="1 WCFXO/0/0 FXSKS  (SWEC: MG2)"
signalling=fxs_ls
callerid=asreceived
group=0
context=from-pstn
channel => 1
callerid=
group=
context=default


/etc/asterisk/chan_dahdi.conf
