Re: [Linphone-users] Can Linphone use iLBC? (Solved)

[Stephen Stocker]

  Hi Clement,

  Thank you a million, that did it. I'd played with everything I could 
think of, without success. It's great to have this working! Thanks again. :)

  I wish I knew anything of the video part of this, but I'm glad you got it 
working on something. I'd also be interested in new codecs. I'm no coder, 
but would be more than happy to test anything you come up with. BTW, I'm 
thinking I ran across a post on this list about that while searching for a 
solution to my problem. Best of luck!

  Steve
