All, trying to set the to field on the B leg of the call from from FS toward the phone: <action application="export" data="sip_to_host=aeonvista.co.uk"/> This seems to work - over-writing the From field in the B leg. <action application="export" data="sip_from_uri=${sip_from_uri}"/> For example in the dialplan I am doing: <extension name="vodafone_+441635698866"> <condition field="destination_number" expression="^(\+441635698866)$"> <action application="set" data="domain_name=aeonvista.co.uk"/> <action application="set" data="domain=aeonvista.co.uk"/> <action application="set" data="bypass_media=true"/> <action application="export" data="sip_from_uri=${sip_from_uri}"/> <action application="export" data="sip_to_host=aeonvista.co.uk"/> <action application="bridge" data="sofia/aeonvista.co.uk/+441635698866" /> </condition> </extension> The resulting SIP INVITE from FS to the B party looks like: INVITE sip:+441635698866@192.168.0.15:2048;line=3sllxdbk SIP/2.0 Via: SIP/2.0/UDP 192.168.0.56;rport;branch=z9hG4bK5D3HQUQUa4XpF Max-Forwards: 69 From: "+441635698863" <sip:+441635698863@aeonvista.co.uk<sip%3A%2B441635698863@aeonvista.co.uk>
