I do not have access to the Exchange side, but on the FreePBX side, I have this for the SIP trunk settings. This location does not have any quality issues like you are describing.

Almost the same configuration I have in the SIP Trunk to UM.

Sorry, I cannot help with the Exchange side. This is the only client I have using this and they have had it setup for years.

Anybody can help me know about how the extensions in FreePBX are finding the Voicemail Systems?

I want to test the voicemails with another Exchange UM, if I am creating one more trunk to new UM will it effect all the users?

This is how I set it up the extensions

Voicemail no on the Voicemail tab

Then on the advanced tab

Just assume, voicemail outbound Route Number is 8888, pointing to Trunk - Exchange UM. IN extension where we can mention this?

I am using - FreePBX 12.0.76.6
