[OpenSER-Users] Set up two SIP to PSTN calls and then connect them

[Andreas Granig]

No. The click2dial in SEMS is triggered via an xmlrpc interface from a 
web application or something like that and creates an INVITE for each of 
the two call legs. These legs appear to OpenSER as two completely 
independent calls and can be accounted as such.
