Open Issues

TCP traffic not supported. Workaround: Use
§
UDP.
No automatic selection for low rate codecs.
§
Workaround: Have enough bandwidth or set
up low rate codecs in the user agent.
No transcoding of RTP streams. No work-
§
around.
Automatic detection and signalling of STUN
§
messages is missing (no proposal in STUN
available). Workaround: Ignore this problem
and accept the additional traffic or manually
set up the user agents.
Bandwidth overflow. If too many channels are
§
open, the traffic will cause a jam. This cannot
be controlled by the gateway, no workaround.
Currently, only Linux is supported. Code com-
§
piles with Windows as well, but set up proce-
dure is not clear (any suggestions?).
