| [Asterisk] How to enable G.722 / Asterisk Right now I've got a small home asterisk setup with a Polycom 321 IP phone and a pair of DECT phones hooked up an Obi110 and Obi100. The only codecs I have enabled are G.711u and G.711A (ulaw/alaw).
I'm going to add a wideband USB headset and softphone and I'm wondering if there's a way to enable G.722 in asterisk in such a way that normal G.711 calls won't get transcoded while still allowing G.722 for the softphone? |

Yes, there is a way to accomplish this.
First, make sure you have the G722 codec enabled via Settings, Sip Settings. Should be just a check mark. You can then prioritize the codec by moving up/down. I have mine set to Ulaw then G722. Save these settings.
For your asterisk extension for the softphone, got to the settings and under the settings disallow, set this to "all". Then directly underneath that, allow, place "g722". Save this extension and reload.
You should be good to go. |

| Thanks. I'm using the CLI and editing the config files manually.
I guess I'll try some different things and see if I can get it to work. |

I'm wondering, if I do that, if regular g711 calls to/from the headset will end up getting transcoded to g722 all the time. |

Is a simple setting on your general and peer in your sip.conf.
disallow=all
allow=g722

That's what I'm trying to avoid, since 99.99% of the calls will be in g711, anyway. |
