VoIP example error: can't connect to SIP-PBX

[liugyer]

Hi guys,

When I use the VoIP example of esp-adf, my board can't be connected with FreePBX.
I have tested with my FreePBX by using phone, so how to fix this issue or how can I debug?
The log as following:

Your SIP server and ESP32 device are on different networks. Check if you can ping from one network to another.

Hi

When I use esp-adf with esp-idf V3.2 which is the submodule of esp-adf repo. It can work, but if I use esp-idf v4.x, the sip server can't be accessed.
And I'm sure that my Lyrat-mini board and FreePBx Server were connected with the same wifi. They should be in a same network.
