    Multi-process server applications using a prefork model are one example. You might have one process dedicated to accepting new connections over the network and maybe doing an initial handshake, and then a bunch of worker processes handling the actual connections. Kamailio's CDP module is built like this (https://github.com/kamailio/kamailio/tree/master/src/modules/cdp)

    PJSIP project

    Project mention: Hi, anyone used PJSIP for P2P connectivity (ICE) | /r/gamedev | 2023-12-06

    Hello, I'm in the process of developing a multiplayer FPS game and recently delved into ICE connectivity (STUN/TURN). Currently, my setup involves a custom matchmaking server in C++, with UDP port handling on the client side through UPnP or a fallback custom relay server. While the current approach works well, I'm exploring options to simplify the project by incorporating existing technologies. I've come across Libjuice and Libpjsip for NAT traversal. Libjuice offers a nice and simple API, but it supports only one person. Hence, I'm considering Libpjsip. I came across their ICE demo script at https://github.com/pjsip/pjproject/blob/master/pjsip-apps/src/samples/icedemo.c and I'm curious about its performance, particularly the pj_ice_strans_sendto2 function. I'm keen to understand how it compares to my current implementation with Berkeley Sockets and whether Libpjsip is a suitable choice for multiplayer P2P games. Any insights or assistance would be highly appreciated. Thanks!

    https://github.com/chan-sccp/chan-sccp should get you started. Follow the docs and their wiki also some good info. You will get base config files and what not to prep your tftp server. Just be forewarned its not a trivial task to get everything setup, I have a dedictaed voice vlan with special entries for DHCP options for tftp and ntp. Also be warned that the sccp phones are basically not secure, if all that doesn't scare you cool, so long as they are just on your local LAN and asterisk is secured properly it really doesn't matter. Also check out this here if your interested in running newer SIP cisco phones as well and want to keep all the UCM features.
