Hello,
Endpoints involved:
Cisco UCM
FreeSWITCH (latest 1.6 GIT)
Call flow is rather simple:
<param name="enable-3pcc" value="proxy”/>
<param name="inbound-late-negotiation" value="true"/>
proxy and bypass media commented out
Receive
<extension name="from_cucm">
<condition field="network_addr" expression="^10\.0\.64\.6[1-6]$">
<action application="pre_answer"/>
<action application="transfer" data="${destination_number} XML internal"/>
</condition>
</extension>
And in Internal plan route to carrier:
<extension name="mts_tascom">
<condition field="destination_number" expression="^(17[0-5]\d\d)$">
<action application="set" data="continue_on_fail=true"/>
<action application="set" data="hangup_after_bridge=true"/>
<action application="bridge" data="sofia/gateway/mts_tascom-1/$1" />
</condition>
</extension>
