I have not done this but something to consider is that there is a huge quality difference in Android phones. It's possibe this is causing you issues if your users have cheaper phones.
OK that's an interesting point. They are all Samsung phones, but I'm sure some of them are super cheap Samsung phones, not flagships.
I also want to mention that I had one user on an iPhone 5 with Cox's OMG Panarama WiFi (crap), setup on Zoiper, and she dropped calls worse than anyone else... I really think her OLD ASS phone was the root of her issue. I replaced her setup with a physical phone (one of two I actually own) and her problems vanished. Of course I changed two things for her - 1) got off her old ass phone 2) moved from WiFi to wired connection.

@Dashrender said in Softphones - complaints:
Should I change this?
Yes.
This is the default order I use.

@Dashrender said in Softphones - complaints:
The previous thread I mentioned spoke about G722, which I've noticed is enabled on FreePBX, but is not enabled by default on LinPhone - should I enable it? Should I move G722 up the list order on FreePBX?
Should I use some other codec?If you are having quality problems, no. Stick to
ulawonly. G722 takes more bandwidth as it is a high def codec.Also,
opusmay help you if Linphone supports it as it was designed for more flexible network speeds. -

Could be that their home internet is shite and saturated. Both, on their WLAN and the ISP side.
This is also a real concern now. I have a great home network and WiFi setup.
But randomly, my calls are simply shit anymore.
Why? Because everyone is home. It is filling up the ISP pipe to the various nodes.

Not just my calls on my deskphone, but also my T-Mobile WiFi calling.

Opus is on LinPhone and enabled by default.

yeah, I definitely know this to be true.. nothing we can do about this.. but troubleshooting to that point is something I still need to do.. Thanks!

Disable Speex. Opus is the replacement for that.
Where is ULAW G711?
-
Here is the default for LinPhone
-
PCMU = G.711
Disable everything but OPUS and PCMU in Linphone.
Change your PBX to only use G.722, OPUS, and ULAW. In that order.
See if you get any improvement.

Yeah, I'm not making phone calls right now....

For comparison, a client site to their PBX also in vultr.

I have people complaining to me about network-related issues. I can't really do anything about it. I show them that there are other people that have been connected to the VPN for days. A couple users with the same ISP were having issues connecting to our remote desktop server. I had them try connecting to their phones via hotspot and it connected to the RD server. Obviously, this isn't a solution, just proving the point that the issue is with the home connection, not the company services/equipment.

Yeah, I've done the same with the phones - On WiFi things were shit, for some, and on Cellular it worked... i.e. home internet was shit, somehow.

@Dashrender said in Softphones - complaints:
I read another post here on ML that was saying WiFi is bad on SIP traffic - is that still true?
That will always be the case. Wifi can improve, but the fundamental issues remain.

@JaredBusch said in Softphones - complaints:
Stick to ulawonly. G722 takes more bandwidth as it is a high def codec.
Actually they are identical bandwidth. That's part of the spec. It's just better encoding. G711 isn't very efficient.
Opus is HD and SMALLER. -
@Dashrender said in Softphones - complaints:
Should I be on a specific codec?
Absolutely, we limit to Opus only. Can't really think of any time you'd want to allow anything else. Opus is HD audio that is adaptable to take advantage of spare bandwidth when available for the best sound, and trims bandwidth when things get tight to keep the best possible audio even when there isn't enough available bandwidth for G711.
Opus is a game changer and a significant reason that we see our phones working flawlessly where others are failing, you need your codec to adapt to real time conditions or else you are stuck either having poor audio always or good audio that has to fail when things aren't pristine.

Cellular is better suited for carrying audio. That's specifically what it was built for. Just like how DECT handles audio better than Wifi.

This is basically what we do....
For the clients to Opus and the Skyetel links to G722.

I have found most of our home users have crappy wifi right from the carrier. The (in most cases) Spectrum provided Ubee gateways with wifi are junk; while may of our other users have old crappy routers (surprisingly, one user is still on a WRT-54G and has no issues). I am in the process of trying to procure some old Unifi AP's and power injectors that I can pre-program and send out to the remote uses and have them plug into their routers just to get something better than the crap Spectrum uses.
