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

[John J C]

Hi Simon,

   Please look at the following scenario. My question will be

1. Can LinPhone be able to handle these scenarios.
2. If not is there any other free s/w available.


            _____                                               _____
           |     |                  SIP                        |     |
           | UA1 |<------------------------------------------->| UA2 |
           |_____|                                             |_____|
            |  |                                                 |  |
            |  |                                                 |  |
            A  B                                                 C  D

   UA1 -> OSIP User Agent spawned by Linphone


   Suppose there are 2 users A and B served by  UA1 and there are 2
users C and D served by UA2. Is it possible to make calls from A to C
and B to D simulataneously. Letz assume there is no proxies in b/w.


Regards,
John

                Life is pleasant. Death is peaceful. It's the transition that's 
troublesome.
