<html><body><div style="color:#000; background-color:#fff; font-family:verdana, helvetica, sans-serif;font-size:10pt">I am testing Asterisk 10 SIP messaging functionality. I can use MessageSend() in dialplan to send messages outside calls between two SIP phones in the same Asterisk. However, I can’t find any document or example to route messages between different Asterisk instances. If I have a phone with extension “123” connect to Asterisk server 10.0.1.105, I am not able to route the message using “exten =>123, 1, MessageSend(sip:123@10.0.1.105)” from other Asterisk servers. Could you give me some advices or point me to related documents on this issue?<br><br>Thanks,<br></div></body></html>
