How to debug and increase connection speed on asterisk?

Question

Asterisk

Hello.

How can I debug the connection speed on the asterisk? For example, such routing.
Lync (SFB) is installed on the smartphone. I dial my mobile number. The call goes to SFB Server -> Asterisk Main - Asterisk Old -> office PBX -> connection establishment. Everything about everything takes almost 20 seconds (!), which is a lot.

Is it possible to somehow optimize the connection speed or track down the main blunts?

Logs, dumps, time synchronization between all participants in the chain, so you can determine where the delay occurs, then analyze the target system.
