Hi All, I have been experimenting with an odbc based freeswitch cluster in amazon ec2 , with opensips doing the load balancing function. I can make calls to mobile and landlines with out any issues with good quality voice , but when i try to call extension to extension freeswith shows Originate Failed. Cause: USER_NOT_REGISTERED , i searched a lot in lists and wiki and fs jira , tried out different dial strings but with out any results.Tried this one "dial-string" value="{presence_id=${dialed_user}@ ${dialed_domain}}${sofia_contact(${dialed_user}@${dialed_domain})}" & this ${sofia_contact(*/${dialed_user}@${dialed_domain})} I have copied the siptrace at http://pastebin.com/Qv79tjXK Appreciate any help in this regard Thanks -- shijujoe
