pjproject VS freeswitch

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!

Things improved a lot thanks to the adoption of the pjsip stack.

When I look at stuff like pjsip, I get the impression, it would be huge amount of work. Am I mistaken?

The first issue I'm facing is I can't find lib folder which is mentioned in Using pjproject libraries for your own application heading in the above-mentioned link. I download the source code from this link.

For client and server, I'm only really familiar with https://www.pjsip.org/. It also comes with a bunch of code for doing phone calls, which really most SIP Stacks were built around. But those parts can just not be used.

PJSIP (https://github.com/pjsip/pjproject) is used as SIP framework

Hopefully an update to allow speed changes will land... https://github.com/signalwire/freeswitch/pull/244

Some clarification on what you mean would be great.

When I look at their organization on Github I see quite a few active projects e.g. "Sharq" - SHARQ Server is an flexible, rate limited queuing system based on the SHARQ Core library and Redis. (https://github.com/plivo/sharq-server) as well as client packages in quite a few languages.

Beyond that the documentation you referenced clearly points out that FreeSwitch (https://github.com/signalwire/freeswitch) is the telephony engine (https://web.archive.org/web/20130314113846/http://docs.plivo...) and the install script from the docs shows that their roots are in Pilvo being a Python web app (https://github.com/plivo/plivoframework/blob/master/scripts/...). I also see a few Django applications in their repositories as well.

Thus, they open sourced their software. Are they open sourcing all of their software? Likely not. It could be that they open sourced much of their code and then got no contributions.

If they weren't receiving any contributions in alignment with their development, there would be no value for them to continue to have that distraction from running their business. It could also be that they didn't have the resources to _maintain_ external facing repositories, issues, and the communities around them.

Providing a more clear explanation of your expectations would help get you the best answer.

FreeSwitch is a telecom stack similar to Asterisk. See here: freeswitch. It would be to support VoIP on the UDMP.
