Looks like current is 84.0.15
http://support.yealink.com/documentFront/forwardToDocumentDetailPage?documentId=143Yeah, and that is where we don't see it.

It is right there.

In other firmware revisions, Opus is in the codec list. But now it is missing.
This is not what you stated in your opening post. You clearly stated several updates.
@scottalanmiller said in Yealink T46S Missing Opus Codec in 66.84.0.15 Firmware:
Anyone noticed that several firmware updates for Yealink T4xS phones seems to be missing the Opus codec

@scottalanmiller said in Yealink T46S Missing Opus Codec in 66.84.0.15 Firmware:
which is the primary reason for getting that phone in the first place?
I will also argue this statement. The reason to get the T4XS series is because that is the current model.
The T4XG series has all but vanished from distribution, even if there is not an official EoL notice for them yet.

It's been multiple for us, not just this one. Older ones have had the issue, then we update and Opus appears. But now we update and it disappears again. So yes, several just as I said. I never said "several consecutively."

@scottalanmiller hi just to let you know I've been looking at opus on Yealink today with out VoIP system which isn't 3cx and I don't know about 3cx so this may or may not apply, and may or may not be easily rectifiable for you, depends how easily you can alter provisioning templates.
I saw that opus was in the web GUI of the phone before it was provisioned on the system. After provisioning: no opus, it was completely missing from both lists for account 1. Look at the codecs for an account you haven't provisioned, it should be there, this will help prove it's available on your phone model and firmware version.
On our system the auto provision system specifies codecs and their preference as part of the provisioning. What I found was that this list didn't include opus, so in the web GUI of the phone, opus was in the list for account 1 until I auto provisioned it. After that, opus was not available to choose.
The test was to open the auto provision config file in a web browser, for me http://URL/Mac_of_phone.cfg and in here I could see the codecs but no mention of opus. The format was also the older format for Yealink autoprovision. (If you are tftp then it's worth finding a tftp client and download the config to check it - don't forget to check the common model file y0000000x.cfg too, if 3cx uses it).
Eg:
account.1.codec.1.enable = 0
account.1.codec.1.priority = 1
account.1.codec.1.payload_type = PCMU
account.1.codec.1.rtpmap = 0account.1.codec.2.enable = 1
account.1.codec.2.priority = 2
account.1.codec.2.payload_type = PCMA
account.1.codec.2.rtpmap = 8account.1.codec.3.enable = 1
account.1.codec.3.priority = 3
account.1.codec.3.payload_type = G729
account.1.codec.3.rtpmap = 18The fix for me was in our auto provision system to add these two lines, so the phone knew about opus and used it highest priority.
account.1.codec.opus.enable = 1
account.1.codec.opus.priority = 0This is the newer provision format for firmware v81 onwards. After adding these lines opus showed up as top of the list of codecs in use.
If you prefer to stick with the older format, the rtpmap for opus is I think 107, it is mentioned in the Yealink administration guide which you'll find on the website under extra docs for your phone. It also mentions another option which is the bandwidth for opus to use, namely narrowband, wideband or fullband - which are applicable to different models differently - eg their conference phone supports FB but none of the desk phones do, only wb, which is why I didn't bother with that setting.
So the answer for me at least was opus was removed from the web GUI because the auto provision file didn't mention it, so the phone doesn't show it as an option.

@scottalanmiller did you ever default the phone after the firmware upgrade with the problem? A corrupted config will cause all kinds of weird issues like this.
First step on weirdness is to always default the phone.
-
@JaredBusch I had the issue a few months back, I did default the phone, it wasn't until yesterday I actually worked out what was going on with it.
I'm not sure 'corrupted' config us a fair thing to say; it did work and was perfect for older models. Incorrect config is more accurate. Outdated maybe more accurate. It's just that normally incorrect config doesn't hide things from the GUI.

Outdated would be corrupted if you have upgraded the firmware. That is part of the firmware upgrade process.
I asked about it because I have rarely had issues with both a firmware upgrade and downgrade causing odd changes to settings that were never specifically specified (aka things left default).
In every case I have worked with so far, defaulting the device on the current firmware has resovled those issues.
I have not had this specific issue ever show up to my knowledge. But then I do not log into phones and check settings. Users do not report that they do not see the "HD" icon but the phone could be using 722 or OPUS to generate that.
-
@JaredBusch for me, brand new phones out of the box never been used before, never been configured, they were not firmware upgraded nor downgraded. The option was there in the web prior to auto provision, not afterwards. Nothing to do with upgrading firmware in my case although I take on board what you're saying about factory default after firmware upgrade being a good practice.
On the T40G phones we've just had it says 'opus' on the screen when using opus for a call; instead of 'HD', which is what you get with G.722.
Sadly, it's my understanding that one of significant reasons for using opus, namely the FEC, is not implemented in Yealink currently. Not any other hardware VoIP phones either (from my limited research - happy for someone to prove me wrong?) I only found mention of it on the Yealink video conference units. And in some mobile soft phones.

It sounds like @lansalot might have been pushing an old config file to Yealink phones with newer firmware, and that old style config MIGHT have been slightly incompatible - and caused the issue. which @lansalot was able to resolve, not by completely modernizing his config files, but instead by adding a few lines to expressly bring OPUS back into the config.

That should not matter. If the config is old and does not have the setting specified at all, it should go to the default value.

Sure, of course you'd like to think so - but bugs do happen... and it appears that it is in this case.
