      Hello,

  We have a Digium E100P card. We use Asterisk.
  When we call a SIP phone from the E1, the call is heard perfectly on both sides.
  We have a problem when we call a phone on the E1 from SIP, using  the Dial application:  Dial(Zap/g1/209,20)
  On the E1 phone we hear a disturbing clicking noise - a few each second -  during the call (on the Sip phone we hear OK).

  Our configuration files are as follows:
  Zaptel.conf
  span=1,1,0,ccs,hdb3,crc4
  bchan=1-15
  dchan=16
  bchan=17-31
  loadzone=uk
  defaultzone=uk

  Zapata.conf

  [channels]
  switchtype=euroisdn
  signalling=pri_net
  pridialplan=unknown
  immediate=yes
  callerid=asreceived
  context=incoming
  group=1
  adsi=no
  echocancel=yes
  channel => 1-15,17-31

       Any suggestions will be highly appreciated.

          Thanks,

           Shaul
