Hi All!
I’ve met a problem with 3CXPhone BLF buttons (free 3cx.com softphone) and Asterisk.
The only information I could find about the way softphone uses to subscribe:
http://3cxblog.worksighted.com/2008/10/understanding-park-orbits-with-3cx.html
They say: "Softphone sends SIP SUBSCRIBE message for the special account “any‐dn”"
It is probably true (below is a part of debug output)
I found out that regardless of software button settings softphone sends “SUBSCRIBE sip:%23any-dn%23”
So, here is the question: is there any way to use such a special way of presence subscribing with Asterisk?
Thank you very much!
