Centos 7
Asterisk 13.1
Noticed a WARNING which filled Asterisk’s messages logfile:
To get rid of it, use bridge_softmix.so module instead of bride_simple.so.
Thanks to Lenar Daminov from our team for research.

jcolp, Asterisk developer:
The bridge_softmix module is more heavy weight as it gets data from each channel, transcodes it into signed linear, mixes it at an interval, and then sends it out. Even for 2 channel bridges it will do this. The bridge_simple module simply exchanges data back and forth without mixing. Frame type 10 is comfort noise which is not currently supported by Asterisk.
