BrainwreckedTech,

Ekiga cannot try to reduce the packet size because of the SIP protocol:
it has to deal with a codec negociation, and it respect user choice to
present all codecs available (and there is many codecs available in
Ekiga) and selected by the user. Reducing the packet will mean dropping
some codecs.

As you explained UDP packets cannot be fragmented, while TPC packets
can. The SIP standard thus ask the application to switch to TCP if the
packet size do not fit in UDP. The issue here is Ekiga do not support
this feature yet, which lead to this bad situation. It was not an issue
until Ekiga supported so many codecs as it is able to do nowadays.
Supporting TCP as well as UDP is a main priority for the project (in
fact for the OPAL lib ekiga uses).

Until this bug is fixed, the best solution is to deselect some codecs in
Ekiga until it fits the UDP packet size.

Best regards,
Yannick
