How to play gsm files (asterisk) on a web page?

Question

Asterisk

Hello!
I need to implement a web page that will display files with a record of conversations. But I can't figure out which codec/plugin/spell is capable of streaming .gsm files.
Tell me where to dig. Any browser and a plug-in for it will suit me for implementation, only the recording in it was played.

Answer 1

Set up the asterisk to output records in vorbis format. It is understood by all modern browsers without additional crutches.

Answer 2

Convert to mp3 or ogg (ffmpeg will help)

Answer 3

quicktime player can play gsm, including a plug-in for browsers
