This is not exactly what you are looking for but it might help you. This is to limit the concurrent calls by callee and the caller (limit set to 1 call ) <context name="start"> <extension name="test"> <condition field="destination_number" expression="^(\w+)$"> <action application="limit" data="hash ${domain} $1 1 handle_over_limit XML over_limit_actions"/> <action application="limit" data="hash ${domain} ${caller_id_number} 1 handle_over_limit XML over_limit_actions"/> <action application="set" data="ringback=${us-ring}"/> <action application="set" data="transfer_ringback=$${hold_music}"/> <action application="set" data="hangup_after_bridge=true"/> <action application="bridge" data="user/${dialed_extension}@${domain_name}"/> </condition> </extension> </context> </context> <context name="over_limit_actions"> <extension name="limit_exceeded"> <condition field="destination_number" expression="handle_over_limit"> <action application="hangup" data="USER_BUSY"/> </condition> </extension> </context> Both limits in the "start" context set the limit in 1 call for callee ($1) and caller(${caller_id_number}), if the limit is exceeded , the flow falls to "over_limit_action" context and busy tone is transferred. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/FS-hash-limit-tp7588453p758845...
