[Telepathy] Problems with audio calls?

[Butrus Damaskus]

Hello!

Since last friday I have problems with audio calls (Emapty ⇐ Psi).
Before, it did work well. Now it doesn't even connect (or better: it
gets disconnected right at the beginning). I installed no updates
betweenn thursday and friday, nor did the other part.

So it can perhaps be some problems with my provider; or with the proxy
servers (both computers are behind the NAT).

Do You know, if there is not such a problem with the proxy servers? It
is strange, that echo at test.collabora.co.uk is offline ATM and I cannot
do any echo test.

Thank You!
