Hello, I would like to receive short messages. The relevant lines taken from extensions.conf are these: exten => 500,1,Answer exten => 500,2,Wait,2 exten => 500,3,SMS(default,a) exten => 500,4,Hangup When I send a short message to the extension with the number 500 the following lines are written to the CLI: -- Executing Answer("Zap/1-1", "") in new stack -- Executing Wait("Zap/1-1", "2") in new stack -- Executing SMS("Zap/1-1", "default|a") in new stack -- SMS TX 93 00 6D 00 00 00... -- SMS TX 92 01 FF 6E 00 00... -- SMS TX 92 01 FF 6E 00 00... -- SMS TX 92 01 FF 6E 00 00... -- SMS TX 92 01 FF 6E 00 00... -- SMS TX 92 01 FF 6E 00 00... -- SMS TX 92 01 FF 6E 00 00... -- SMS TX 92 01 FF 6E 00 00... -- SMS TX 92 01 FF 6E 00 00... -- SMS TX 92 01 FF 6E 00 00... -- Channel 0/1, span 1 got hangup I also tryed sending the short message from another number which gave me the following output: -- Executing Answer("Zap/1-1", "") in new stack -- Executing Wait("Zap/1-1", "2") in new stack -- Executing SMS("Zap/1-1", "default|a") in new stack -- SMS TX 93 00 6D 00 00 00... -- SMS RX 91 16 04 0B 81 10... -- SMS TX 95 02 00 00 69 00... -- SMS RX 94 00 6C 0B 81 10... -- Executing Hangup("Zap/1-1", "") in new stack I do not know what all these lines beginning with "SMS" mean but I would like to understand them. I would be happy if someone could explain them to me or could give me a pointer to some documentation. At the end I would like to see the short messages in /var/spool/asterisk/sms and the logs in /var/log/asterisk/sms (or a subdirectory of these directories) as it is explained on http://www.voip-info.org/tiki-index.php?page=Asterisk+cmd+Sms. This document also mentions a script called "smsin". I do not have it. Where can I find it? Greetings, Martin
