hello, i have a sip provider with multiple DID´s and they send me all calls with the same invite, only the To field in the SIP header is different. how can i read the To field in the SIP header to be able to make a call routing based on the To field? i tried the following rule but it doesnt work: --------------------- <include> <extension name="public_test1"> <condition regex="all"> <regex field="destination_number" expression="^provider1$"/> <regex field="${sip_h_To}" expression="43717072377"/> <action application="set" data="effective_caller_id_number=7021"/> <action application="set" data="effective_caller_id_name=thomas"/> <action application="answer"/> <action application="transfer" data="6011 XML inbound1 "/> </condition> </extension> ---------------- the To field in the SIP header looks like this: To: <sip:43717072377@193.43.148.37> thanks a lot for help! best regards, thomas
