Unfortunately, some German ISPs send the wrong SIP access information when using not their rental devices. This script was created to automatically check the access information with known registrar domains.

./registrar-test.sh -u 12349876543 -p

Script requires:

• SIPp 3.6.1+ (see https://github.com/SIPp/sipp)

1. Download latest release from https://github.com/SIPp/sipp
2. Install requirements with sudo apt install cmake libncurses5-dev libsctp-dev libpcap-dev libssl-dev
3. Extract SIPp archive and go into directory
4. Run cmake . -DUSE_SSL=1 -DUSE_SCTP=1 -DUSE_PCAP=1 -DUSE_GSL=1
5. Run make
6. Move binary sudo mv sipp /usr/local/bin/sipp && chmod +x /usr/local/bin/sipp
