[Asterisk-Users] Sipura SPA-841 distinctive ring

[Gareth Blades]

Reading http://www.voip-info.org/wiki-SPA-841 I have configured Asterisk
with the following dialplan to ring using 'Simple-1' but it is not
working.

exten => 6150,1,SetVar(ALERT_INFO=Simple-1)
exten => 6150,2,Dial(SIP/6152,4,t)
exten => 6150,3,Dial(SIP/6152&SIP/6148,4,t)
exten => 6150,4,Dial(SIP/6152&SIP/6148&SIP/6143&SIP/6153,15,t)
exten => 6150,5,Voicemail(u5150)
exten => 6150,103,Goto(3)
exten => 6150,104,Goto(4)
exten => 6150,105,Goto(5)

Any ideas?

Thanks
Gareth
