[Freeswitch-users] I need help to handle incoming calls from Cisco AS5300

Hi Folks, I have a Cisco AS5300 in a different domain as FS, It will send calls to FS with format ( prefix + phone number ) through sip with codec G723. here is the configuration setting on FS. Set the default sip_profile without auth ( no need register) <param name="accept-blind-reg" value="true"/> Set the default dial-plan with expression to handle prefix <condition field="destination_number" expression="^9090180012345678$"> <action application="bridge" data=" sofia/default/180012345678@sip.gateway.com"/> </condition> </extension> what else i need to setup? AS5300 keep getting error code 27. Thanks for any help, StevenLee
