Hi all, We have Cisco's packet tracer for CCNA course, which helps us to understand the real-time scenario of networking between several devices which can be installed at home PC, office PC, anywhere.
Likewise, do we have any such open source for Session Initiation Protocol. I know that there are Sipp, MAPS for testing when you have real SIP phones next to you. But do we have software(s) which would help us without SIP phones like in a real-time environment ? Google didn't help me, can you guys ?
Thanks.
