Greetings! I installed freeswitch from the yum repository on a clean centos 6.5, loaded mod_sms and tried to send a text message between two clients. I use extensions 1001 and 1002 for testing. Had to change the default chatplan to "public" and when I send a message from one client to the other the debug console prints out: -- 2013-12-13 11:48:20.545501 [INFO] mod_sms.c:336 Processing text message 1002->1001 in context public Chatplan: 1001 parsing [public->demo] continue=false Chatplan: 1001@172.16.1.10 Regex (PASS) [demo] to(1001@172.16.1.10) =~ /^(.*)$/ break=on-false Chatplan: 1001@172.16.1.10 Action reply(Hello, you said: ${_body}) 2013-12-13 11:48:20.545501 [DEBUG] sofia_presence.c:224 Can't find registered user 1002@172.16.1.10 2013-12-13 11:48:20.567453 [WARNING] sofia_presence.c:4523 Not sending message to ourselves! -- and the demo reply doesn't show up on the sending device. When I invoke "sofia_contact 1001" from fs_cli, however I get this: sofia/internal/sip:1001@172.16.1.10:54302;ob Invoking "sofia_contact 1000", which is not used at the moment returns this: error/user_not_registered So, why can't sofia_presence find the registered user when it's listed correctly and how do I fix this? Thank you in advance. P.S. Before installing from the RPM repository I compiled it from scratch following the installation guide, but I had the exactly same problem. Kind regards, Iskren Hadzhinedev
