<div>MTP is basically creating a known rendezvous point that both call legs can reach and there is a guard at the gate that says, “pay no mind to the man behind the curtain, it’s just magic”. traces and debugs would show you what’s going on but you got to go
through a ton more effort to get an RCA.<br>

<div dir="ltr">We'll really need a "debug ccsip messages" for an entire good/bad call to see what part the carrier is getting hung up on. MTP Required would probably be a good fix but it's a bit bad practice to rely on MTPs where not necessary. MTPs definitely
make troubleshooting more difficult.</div>
