Hi, I want to reject an incoming call from a mobile number in the public context and callback to it how should the dialplan look like: <include> <extension name="public_did"> <condition field="destination_number" expression="^(88888888)$"> <action application="set" data="domain_name=$${domain}"/> <action application="log" data="INFO domain is $${domain}"/> <action application="set" data="callerID = $${caller_id_number}"/> <action application="log" data="INFO src number is $${callerID}"/> <action application="respond" data="503"/> <action application="bridge" data="{sip_auth_username=1003,sip_auth_password=R@D ~o$121$@IIITD}sofia/external/1003@52.38.67.78 9769658019"/> <!--<action application="respond" data="reponse_info" data="407"/> --> <!--<action application="transfer" data="5000 XML default"/> --> </condition> </extension> </include> Regards, Deepika
