Re: [Linphone-developers] Can LinPhone handle multiple calls???

[Simon Morlat]

Hi,

With osipua (the user agent library of linphone based on oSIP), you can
create several user-agent with the same program, each user-agent being
able to answer to several dialogs simultaneously.
The limitation for linphone is not osipua, but the audio processing of
simultaneous calls.

Yes, you can modify linphone to do this. However this is not very
interesting. I think having a conference server based on osipua, able to
accept multiple calls and mix audio streams would be better.
