Ok - tnx - i'll try to implement this and write a short howto if it
One CPL related thing which isn't clear to me yet:
According to the Admin Guide at
http://www.iptel.org/ser/doc/seruser/seruser.html [Open]SER is not
call-stateful. The way that I understand this is that a BYE is (for SER)
totally unrelated to the INVITE request.
But how does this work in combination with the CPL logic? E.g. a user is
busy and so the incoming call gets forwarded to 'foo at bar'. How does the
CPL engine know that the BYE packet should also be forwarded to
'foo at bar' instead of processing the call logic from the beginning?
