siptest

Performs a SIP registration and then optionally places a call into an echo test, plays audio, and verifies that the audio is echoed back clearly. The result is returned using shell exit codes.

detectsipalg

Can be used to detect SIP-ALG packet manipulation, common in many consumer routers, and often implemented incorrectly.

    cd pjproject-2.0.1
    ./configure
    make dep; make
    cd pjsip-apps/src/python
    python setup.py install

Sample usage:

siptest --username=simon --password=secret --server=sip.example.com
echo $?
0

siptest --username=simon --password=secret --server=sip.example.com \
    --number=8888 --wav=8000hz.wav
echo $?
0

Exit codes:

0 - SUCCESS

2 - UNKNOWN_USER
3 - BAD_PASSWORD
4 - CONNECT_FAILURE_HOST_BAD
5 - CONNECT_FAILURE_HOST_GOOD
6 - AUTH_FAILURE
7 - FREQUENCY_MISMATCH_FAILURE
