X3SP Stops receiving audio.

[mitchell]

I have a system that is hosted by 3cx. There are two locations with two SBCs. One location has no problems. The other currently has one user and she is having problems with calls audio. The incoming audio becomes garbled and sounds like a cell phone going out of range. Incoming and outgoing calls. Outgoing audio has no problems at all. Sometimes it starts almost immediately other times a minute or two before it stops working. The phone's firmware is up to date and so is the SBC's. The other location has no problem at all and is using X$SPs also. She put the 3cx app on her phone and it worked fine using the same network. Any ideas?

Hi John,

A big thing that can save you some time (and an excellent starting point) is to check whether:

1. This affects only trunk calls or also affects internal extension to extension calls

2. If internal calls are also affected, isolate whether only calls from site-to-site are affected or if calls within the same site (ie. behind the same SBC) are also affected.

This will dictate which direction you need to start looking at and should cut down the time needed to troubleshoot.
Ignore the apps for now, they don't use the same path as phones.
