Re: [Linphone-developers] Multiple calls

[Aurelien Bouin]

Hi,
Here is attached an implementation of the multicall with the new git head, 
please test it as much as you can...
The hold functions are handled in console and in gtk too... I am also attaching 
some pictures that show the hold status feel free to change it ...
Thank you ...
