Hello,
I am not satisfied with the call quality from the iOS App to eg. the mailbox on my external 3cx server.
I am looking for advice, how to narrow the following problem:
Local network: 1G fibre, consumer quality/no SLA, no known congestion or problems
Server: located in a a fairly common datacenter, connection can be assumed to be sufficient.
I have observed the following thing, from the same network:
1. Using the AVM FritzBox as an extension and a handset connected via DECT, I do not experience any problems. (the fritzbox is connected via Ethernet-cable to the fibre-router)
2. Using the iPhone on the fibre-routers WiFi, depending on the codec, I experience a very low quality, crackling noise, the indicator inside the iOS app sometimes switches to yellow or red.
I do not understand, why there are such quality problems from the iPhone app, while the Fritzbox seems to work fine. The WiFi network or the router do not seem to be congested, I tested both the 2.4 and 5 Ghz networks. Any bandwidth tests from the iPhone result in at least 100Mbps for up- and download bandwidth if I move to the places with the worst possible reception.
The 3CX tunneling is enabled.
The latency/ping between home network and server is about 25ms.
Any ideas how to proceed. Any kind of best practice settings I should try?
