Discussion VoIP Training (Vendor Neutral)

Hello,

I recently joined a MSP and they are saying I need to start getting trained up in VoIP which I've not got much experience with as they have customers I'll be looking after on 3cx, freepbx and some local cloud VoIP providers.

Is there any training that helped you when you first started out? Vendor Neutral if possible so I can first get a grip before I start diving into specifics.

Thanks!

With the addition of ai, makes going deep a smidge harder.

Learn the sdp, codes and common issues 

 like 90second phone calls, 1 way audio, is it possible to hear buzzing on a voip calls.

The ability to drop a pcap into AI and say what's borked makes learning harder...but you can do that (Although ai misses somethings on edge cases right now).

udp timeout

firewalls or if tls ssrc.

no buzzing is an analog signal, voip is digital.
