Hello,
I have a problem with linphone and answering calls when multiple callers originate to the linphone extension at once.

My setup is like this:
My PBX is an CentOS 5.5 with Asterisk 1.8 and FreePBX 2.7.
There are three Linphone clients (3.4.3, 2x Windows 7 (x64) and 1x Windows XP) and two hardware phones (Aastra). Everything seems good, except that if two or more agents calls the same Linphone-client, the Linphone-client cannot answer any of them. This is true for both the graphical client and the CLI-client.

If I terminate one of the incomming calls, I can answer the secound one.

I have tried different clean installs, same failure on both WinXP and Win7. Aastra-phones are able to answer if they are presented with multiple callers at once.

I couldn't find any one else with the same problem in the mailing-lists or elsewhere, but I thought that there may be any one out there has experienced the same and maybe has a solution?

Thanks!
Stian
