[Freeswitch-users] Caller ID prefix missing

Hi, when I place a call over the gateway to the PTSN I see the dialed number without the leading 0 prefix in the history of my Grandstream GXP2140. Is there a way to add the 0 back again? Thank you <include> <extension name="isdn-outbound"> <condition field="destination_number" expression="^0(\d+)$"> <action application="set" data="effective_caller_id_number=${outbound_caller_id_number}"/> <action application="set" data="effective_caller_id_name=${outbound_caller_id_name}"/> <action application="bridge" data="sofia/gateway/isdn/$1"/> </condition> </extension> </include>
