Hi there,

I have PRI connection with my chan_dahdi.conf is:
context=text
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
canpark=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
relaxdtmf=yes
rxgain=0.0
txgain=0.0
group=1
callgroup=1
pickupgroup=1
immediate=no
language=urdu
pridialplan=unknown
prilocaldialplan=unknown

group=1
signalling=pri_cpe
switchtype=euroisdn
channel=>1-15,17-31

and my system.conf is:
loadzone=us
defaultzone=us
span=1,1,0,ccs,hdb3
bchan=1-15,17-31
dchan=16

I am making auto calls, but after few minutes my dahdi channel status shows the “PRI flag: call” and it keeps the same status until i reset the channels. Due to this, most of calls get fails.

Please let me know if this is carrier end issue? or is there anyway i can clear this flag after calls completed, so next call on same channel will not get fail.

Did you ever find a solution? I have a channel or two that gets into this state.

No, i made the script which restart dahdi and asterisk after every 1 hour, then i update the Dahdi and did face this issue. Not sure if it was from carrier end or with dahdi version.
