client

This is a SIP client that sends an INVITE and then sends PCMU audio for a local file. It is useful to test the sip server.

Running

At this time no options exist, go run . is all that is required. It connects to a SIP server running on the local machine and will send audio.

This program expects a audio.mkv to be in the directory. The file should contain PCMU in 20ms samples with a samplerate of 8000 and one channel. You can use the command below to convert a file, or use this pre-encoded one.
