How to call from FreePBX to an analog PBX with pauses for beeps?

Question

Asterisk

Hello!
Not long ago, we deployed ip-telephony based on FreePBX Distro in an office with an analog PBX, purchased several sip-phones. We set up the whole thing in such a way that from a sip-phone via FreePBX the call goes through the FXO gateway and then to the analog PBX.
The exit from the sip-phone to the PBX is through the key 0, pause, then we hear a beep, then we dial the internal analog number of the employee (ХХХХ), or if you need to call the city or cell phones, then we dial 0, pause, beep, 9, pause, beep and 8945ХХХХХХХ.
It is necessary to automate dialing somehow so that the employee from the sip phone does not stand the pause with beeps, but simply dials the desired number. For example, if you need to call an analog internal number, then 0 and the number of the employee XXXX (0XXXX), if to the city or cell, then 08495ХХХХХХХ (08926ХХХХХХХ).
This is done in Dial Patterns in my opinion, but I rummaged through a bunch of information - I didn’t find anything concrete.
There is something similar here How to make Asterisk call an analog PBX with extension dialing? but this is for pure Asterisk and it is not at all clear how to implement it in FreePBX.
Thanks in advance!

You go to outbound routes, add a route to an analog PBX, write
0XXXX
09XXXXXX in the pattern
, etc.
