3CX SBC running on Pi 3B+ -

[NickEmpireComm]

Good Morning

I have a customer with 47 phones across four sites. Each site has an SBC with the largest site having 24 phones.

All phones across the board are Yealink phones with the following BLF
- 1 Line Key
- 4 Shared Parking Keys
- 5 Custom speed dials for paging.

Reception Phones have all the same plus an additional 15 speed dial buttons.

I'm experiencing the following weird issues
- Paging intermittently goes to a busy signal vs ringing (Standard paging, not multicast)
- It rings all phones for one of the paging groups
- Sometimes parked calls don't appear on all phones.

Sine the main site is also the most active (most users at any given time) and has the most phones, I'm suspecting I may need a second SBC to balance the load or upgrading from a Pi to a more powerful solution.

Any suggestions are appreciated.

Did you check the CPU & RAM usage on the SBC editing interface on 3CX console ? (When there is activity, calls, ...)
