[Asterisk-Users] SIMPLE support in Asterisk?

[Kerker Staffan]

Hi
this SIMPLE support things sounds really good. too bad i'm not a
programmer otherwise i would most certainly try to fix this. this
together with a full SIP proxy possibility (or at least SIP URI
handling) would be great! anyone else interested in this? anyone with
programming knowledge interested in this? =)
