Hi, I just started to learn about Asterisk and I am having problems with my first try. I was success installing Asterisk 18.4.0 on an AWC EC2 with Ubuntu 20.04.2 LTS (GNU/Linux 5.4.0-1047-aws x86_64). I also was able to register to my SIP Trunk and place incoming calls from the PSTN to some softphones, The call stablishes and the audio goes through but for each call on the CLI console I get a warning saying “channel.c:5674 set_format: Unable to find a codec translation path: (slin) → (g729)” I don’t know if that is some thing I should care about.
On the general section of the sip.conf file I have the following lines:
I use them because the SIP Trunk provider told me that I have to use G729
The softphones are:
Linphone Android 4.4.3
Zoioer5 5.4.12 for windows 64bits
Please any help will be appreciated
