[Asterisk-video] How to test Sipp as client to connect Asterisk

[tran quoc tuan]

Hi all,
I have tested successfully Softphone as client to connect Asterisk as Server.
I want to test Sipp as client to connect Asterisk as Server, because I
want to test with more and more users.
I have tried to create a scenario but it doesn't create a session.
In Asterisk, it returns message : 488 Not Acceptable here. I don't
understand this reason, because SDP in message INVITE, I copy from
message of Softphone.

I have attached my scenario,
Thank in advance for all helps!
Best regards,
T.Q.Tuan
