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 ?

ESP32 SIP registration problem - Qualify-Asterisk related
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...

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. 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 ...

ESP32 adf VOIP not making a call
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...

Re: SIP required authentication
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 ?
regards
Ludo

SIP required authentication
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...
