I installed asterisk-1.4.15 on Fedora core 6 and all my BT102 SIP phones were registered to asterisk, but when I called one extension, I got only a busy signal.
On the other end, I can call the extension for the voicemail, for example :
exten => 250,1,VoiceMailMain() , and hear the pre-recording voice message
Please help me
Thanks in advance
