Is "501 Not Implemented" a bad sign?

Asterisk Asterisk Support

Hi, eveyone
I’m debugging one problem with Arris EMTAs that do not work with asterisk well.

I was wondering how bad a “501 Not Implemented” could be. Also, I’m not sure what is it exactly that is not implemented

I am not 100% sure but try checking the codec’s you are using as well as the type of DTMF.

It looks like the target does not support OPTIONS, since it’s reply says:

Has anyone achieved making Arris EMTAs work with Asterisk ?
