[Freeswitch-users] Bridging after sending dtmf

16 Mar 2012

      Hello,

Here are two dialplan examples of the simple thing I'm failing to do -
bridge inbound (external profile) and outbound (internal profile) sip
calls after sending some dtmf sequence to the outbound leg. In both
cases (and several more I've tried) calls are bridged right after
outbound leg picks up and dtmf are sent after the bridge. I would
greatly appreciate your help/hints.

Thank you.

Alex

Example 1.

<include>
  <extension name="bridge_pre_exec">
    <condition field="destination_number" expression="^preexec$">
      <action application="log" data="INFO bridge_pre_exec request
(${dtmfseq}) (${destination}) (${destip})"/>
      <action application="answer"/>
      <action application="set"
data="bridge_pre_execute_bleg_app=send_dtmf"/>
      <action application="set"
data="bridge_pre_execute_bleg_data=w#w${dtmfseq}"/>
      <action application="bridge"
data="sofia/internal/${destination}@${destip}"/>
      <action application="hangup"/>
    </condition>
  </extension>
