Algorithm_stream issue

Hi, To get the VOIP to work, I need to have an AEC implemented, otherwise the application is useless. I understand the concept of element in a pipeline, and am trying to understand better the concept. When looking into algorithm_stream.h, it shows .rec_ch = 1 .ref_ch = 1 is my assumption correct tha...

Lyra't mini AEC

Hi, the espressif documentation shows : ESP32-LyraT-Mini is a lightweight audio development board based on ESP32-WROVER-E, which implements AEC, AGC, NS WWE (wake word engine) and other audio signal processing technologies. When you say "implements AEC", does this mean it is done in Hardware, and no...

Voip sleep mode

there is an example of modem sleep in github esp-idf/wifi, but not in esp-adf.
Is it possible to implement modem sleep in the VOIP application, taking onto account that there is a need for SIP communication with the sip server.
any suggestions on how to implement this ?

Voip echo cancellation

Hi, In the espressif document on voip (attached), it is mentioned that it includes a dual channel acoustic echo cancellation (AEC).

Re: ESP32 adf VOIP not making a call

Hi, Have Asterisk working with PC-microsip and Android. Am now doing the same with ESP32, and start to see results. Problem is that the VOIP_APP does not properly handle registration, as I can see Asterisk to register the ESP, but in the program, the sip_state_t sip_state = esp_sip_get_state(sip); g...

Re: SIP required authentication

Hi, Is anyone looking at this ? I further looked into this, and have the feeling the code is not working.

Hi, I succeeded in registering the ESP32 to Asterisk, and did this also with a softphone. But I cannot find a way to make now a call, it is only re-registering. Is the example for the VOIP really making a call ? If so, how is it done ? Which button is being used to start a call ? (then I can look in...
