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...

In attached document, it says that espressif has an aec solution. Please explain why this solution is not provided/shared?

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 ?

Hi, In the espressif document on voip (attached), it is mentioned that it includes a dual channel acoustic echo cancellation (AEC). When I call with my Android phone, I hear my words in my ear with delay, when I call my Pc, no echo happens. How/where in the Voip app/esp-adf can I see what is impleme...

When using a softphone on my PC, registration to Asterisk (on my laptop) registration works fine. (also calls work). When using ESP32, it registers but says Unreachable when I have put Qualify=yes in Asterisk. When I change qualify to no, reload asterisk, exit, then change again qualify=yes and relo...

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...

Hi, Is anyone looking at this ? I further looked into this, and have the feeling the code is not working. I can see in Asterisk that I am registered, but am unreacheable, Also, in the ESP32 SW, there is a "SIP_EVENT_REGISTERED" that should be visible on the screen when the ESP is registered ....but ...

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...

Hi,
In the mean time, I get authentication when using the latest esp-adf-v2.0-beta1
But now I get a strange OK-error.
SIP: Error register device Success
How do you explain the the error is a succes ? Should this be SIP: register device success ?

Hi, Making a new attempt on VOIP with ESP32 audio board and Asterisk. I get a 401 unauthorized, but as far as I understand, this is created by the pbx , and on this, the ESP32 should send a response with the right credentials. (realm, nonce...) Then I get following : I (310803) SIP: Required authent...
