Re: [Linphone-developers] are there any updates planned for bzrtp?

[Ben Sartor]

Hello Eli, hello all,

I'm certainly interested in having some more crypto algorithms in bzrtp too. 
Furthermore I would have some time to help with the patches.

Maybe we can do something about getting the patches merged. E.g. I could 
review and test your (Eli's) patches before requesting to merge them (and vice 
versa). This would hopefully reduce the time Belladonne has to spent on it.

What do you think?

Best Regards
 Ben
