Hi sr-users, The TLS traffic generation scripts are online here: * SIP library - fork of sippy/b2bua - use main-async branch https://github.com/space88man/b2bua This branch is an async refactoring of sippy; the master branch of the repo is the regular sync+elperiodic version. * runtime UA generation scripts: https://github.com/space88man/multiuac-tester This repo contains the TLS-client transport (sippy out-of-the-box supports UDP); also gratuitously uses the match/case syntax for fun (so needs Python 3.10) * no documentation: the scripts/t_register.py and scripts/t_phone.py should give you an idea how to create UACs. The script in the talk is scripts/t_register.py - creates SIP UACs that sit in an infinite loop and do REGISTER and keepalive ('\r\n\r\n'). Disclaimer: this is not a SIP-scenario framework like SIPp; SIP messages are programmatically created using sippy; e.g., the test scenario does not need to handle RTP media so the SDP body is a hardcoded string. Regards S-P
