[asterisk-dev] CSTA support for asterisk... or begining this module/project

[Klaus Darilion]

Hi!

AFAIK Microsoft's OCS uses CSTA over SIP. Would opencsta.org be useful 
for sending CSTA over SIP too?

Maybe in this case it would be easier to implement CSTA server directly 
in Asterisk and use chan_sip as transport for CSTA.

regards
klaus
