sorry but it didn't work. yes, it may be the reason. i am using sangoma a101d which may not support mtp2 signalling. when i changed the mtp2=16 to dchan=16. ztcfg starts working well but asterisk didnt load chan_zap.so and gives this error [Jun 25 17:16:44] ERROR[20072]: chan_zap.c:12826 linkset_addsigchan: Unable to open SS7 sigchan 16 (Device or resource busy) my zaptel.conf is ############# # Autogenerated by /usr/local/sbin/sangoma/setup-sangoma -- do not hand edit # Zaptel Channels Configurations (zaptel.conf) # loadzone=us defaultzone=us #Sangoma A101 port 1 [slot:0 bus:2 span:1] <wanpipe1> span=1,0,0,ccs,hdb3 bchan=1-15 #hardhdlc=16 #mtp2=16 dchan=16 bchan=17-31 and zapata.conf is ################################### ;autogenerated by /usr/local/sbin/config-zaptel do not hand edit ;Zaptel Channels Configurations (zapata.conf) ; ;For detailed zapata options, view /etc/asterisk/zapata.conf.orig [trunkgroups] [channels] context=default 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 ;Sangoma A101 port 1 [slot:0 bus:2 span:1] <wanpipe1> ;context=from-pstn ;group=0 ;signalling=pri_cpe ;channel =>1-15,17-31 switchtype=euroisdn signalling=ss7 ss7type = itu linkset = 1 pointcode = 5678 adjpointcode = 1234 defaultdpc = 1234 sigchan = 16 cicbeginswith=1 channel = 1-15 cicbeginswith=17 channel =17-31 On Sat, 28 Jun 2008 21:44:19 -0500 (CDT), Matt Fredrickson wrote > ----- "shoieb_arshad" <shoieb_arshad at comsats.edu.pk> wrote: > > > hello > > i am getting an error when i set mtp2=16 in zaptel .conf > > > > """"""""""""""""" > > Changing signalling on channel 16 from Clear channel to MTP2 > > ZT_CHANCONFIG failed on channel 16: Invalid argument (22) > > Did you forget that FXS interfaces are configured with FXO signalling > > and that FXO interfaces use FXS signalling? > > """""""""""""""""" > > can any bosy help me>??????? > > Something I just thought of... it could also be because you're using > a board that doesn't support MTP2 signalling.
