Have you confirmed that the sip_history_info parameter is even defined at the time bridge the call? Add this line line right before the bridge and make a test call: <action application="log" data="NOTICE SIP history for this call leg is: ${sip_history_info}"/> Check the console for an orange colored line with the sip_history_info. On a different note: what information in the sip_history_info are you needing? In any case, you might be able to set an X header in server A that you can then collect in server B. I recommend checking this section of the mod_sofia page: http://wiki.freeswitch.org/wiki/Mod_sofia#Channel_Variables HTH, MC On Wed, May 30, 2012 at 9:04 PM, Sanath Prasanna <ahe.sanath@gmail.com>wrote:

Server A ip: 10.1.1.252 Server B ip: 10.1.1.253

Here is the dial plan of server A. <include> <extension name="op-inbound"> <condition field="destination_number" expression="^(\d{8}[1,2])$"> <action application="bridge" data="sofia/internal/$1@10.1.1.253"/> </condition> </extension> </include>

Here is the acl.conf.xml server B <list name="domains" default="deny"> <!-- <node type="allow" domain="$${domain}"/> --> <node type="allow" cidr=" 10.1.1.252/32"/> </list> Server A: <list name="domains" default="deny"> <!-- <node type="allow" domain="$${domain}"/> --> <node type="allow" cidr=" 10.1.1.253/32"/> </list>
