In general, call swapping is available
for both SIP and H.323 calls, as well as
for any combinations of the two.
If you are connected to an external
multiway you may also under certain
conditions initiate a video conference
from your system.
More on this can be found in

Initiating a

Video Conference From Your 150 MXP

Note that if conference initialization is
enabled by means of external multiway,
call swapping will no longer be available
for H.323 calls.
