sipml5 + freeswitch 1.6 - codec negotiate error

[scottzhang]

I am using latest sipml5 with lastest git checkout version of freeswitch. After some trying, now I can call from freeswitch, and other part , which is linphone can ring but immediately go silence.

in freeswitch console, I read "codec negotiate error" each time, which make caller hang up. When use 2 linphone calls each other, no "codec negotiate error" happened and they can talk.

So what can I do to make it work?
