ESP32-LyraT V4.3: Voip Example Problem
ADF V2.2. Have Asterisk working with one ESP32 and Android phone. But there is no sound with ESP32 to ESP32, any idea?
Re: ESP32-LyraT V4.3: Voip Example Problem
Hi.
If each esp32 work with Android, they must work between themselves too.
Also, have you noticed low quality sound from speakers connected to esp32?

Re: ESP32-LyraT V4.3: Voip Example Problem
Yes, it should be work between two ESP32, but fail now. If I use voip example from ADF, it also failed with Android. I use g711enc_pipeline_open() and g711dec_pipeline_open() from OLIMEX sip_phone_example project to replace recorder_pipeline_open() and player_pipeline_open(), it works with Android, and gets low quality speaker in ESP32 side. For low quality issue, do you have any suggestion? I attached the voip_main.c, thanks in advanced.

Re: ESP32-LyraT V4.3: Voip Example Problem
The "voip_example" code must work from the box, I checked it for different boards. You should try to run it, too.
Decoding one channel stream into two channel works incorrectly, IMHO. It is the reason for low quality of speakers sound.
And it is the question for ADF support team ))

Hi,
I attached two ESP32 logs, one is working with Android and another is NG without voice.
The NG log lacks "SIP_RTP: send task, remote addr=192.168.5.152" in the line 276.

Re: ESP32-LyraT V4.3: Voip Example Problem
Hi kentavr,
What's the version of ADF and voip you test? There is a AEC function added in voip example two months ago. I do not sure if this is the problem in my ESP32-Lyrat board.
Acoustic Echo Cancellation (AEC) :
Software AEC
only support MINI board with our algorithm stream
Hardware AEC
You can use MSC board or other board that support AEC features

Hi Shadow.Yang.
I noticed "401 Unauthorized" errors in your logs. You should check origin of those errors.
Also, you use PCMU(ulaw) codec in your code, try to use PCMA instead. I had problems with PCMU implementation of ESP32 voip.
Rebuild "voip_example" with PCMA, and don't forget to make changes on SIP server too, to accept alaw codec from extensions.
I use latest version of ADF(and examples) from here: https://github.com/espressif/esp-adf.
Thanks for AEC advice. Unfortunately it is for microphone part, not for speakers. And I'm sure it is decoding problem: one channel -> two channel.

Re: ESP32-LyraT V4.3: Voip Example Problem
Hi,
Yesterday I received the olimex test board and created the olimex sip phone example and also noticed bad audio quality.
First I thought that volume was too high but same problem with headphones.
Don't have the board here at home but could it be related to this :
