Hello, we are developing an open source, distributed, scalable media processing framework (using excellent Freeswitch as the media core) and we are implementing a Verto protocol proxy as part of it. We have some doubts related to the bandwidth test implemented in 1.6.5. Please tell me if I am correct: 1. First, the client sends "#SPU (number1)" where number1 is the amount of bytes it is going to send next with "#SPB" messages (262.144 in my case). 2. Then it finishes with a "#SPE" message. 3. The server answers then with a #SPU (number2), and seems to send 10x bytes (2.621.440 in my case) What does number2 mean? 4. Then, the server finishes with a "#SPD (number3)". Again, what does number3 mean? More questions would be: - Is it possible to put several (many) of concurrent 'invites' over the same verto connection or you really need to open a new connection for each call? Would it be efficient? - Is it possible to 'insert' a channel into Freeswitch without using any endpoint? (Verto or SIP) I mean, an API for sending an SDP and destination number (over the event socket connection for example) and getting a reply SDP from Freeswitch? Thank you very much in advance, Carlos Gonzalez.
