[SR-Users] [ot] lightweight sip app for auto-answering with play file and echo mode

[Juha Heinanen]

Regarding echo, one can use same kind of baresip accounts file as
with play, such as

<sip:echo at test.tutpro.com>;auth_user=echo;auth_pass=xxxxxx;outbound="sip:192.168.43.82:5060;transport=tcp";ptime=20;audio_codecs=OPUS/48000/2,PCMU,PCMA;regint=600;pubint=0;regq=0.5;sipnat=outbound;answermode=auto

The difference is that in config file, these lines are needed:

audio_player            aubridge,pseudo0
audio_source            aubridge,pseudo0
module                  aubridge.so
module_app              echo.so
