I would like to know what are the main differences between Asterisk and SIP in OpenFire.
I already tested Openfire & Spark with SIP phone, and is working. I am wondering if Asterisk is better for VoIP applications.
Later on I would like to make a “connection” betwen my OpenFife server and a Cisco IP Phone 7945G (connected to the company phone system).
Actually, I would like to be able to call from Spark (or other) client from PC to a Cisco IP phone connected to the company phone system.
