AFAIK, using H.323, if the other end supports video, it *must* support
H.261 codec.

see e.g. "While video capabilities are optional, any video-enabled H.323
terminal must support the H.261 codec; support for H.263 is optional."

As Ekiga only support H.261 video codec for the H.323 protocol, it seems
there is an issue with the other end, or a bug in ekiga which is
unlikely as it supports this feature since a long time now.
