In October, Cisco offered $3bn (£1.8bn) in cash to acquire Tandberg, in a move designed to strengthen its position in video conferencing. However, some Tandberg shareholders have resisted the takeover, despite Tandberg management's backing for the Cisco offer.

Once that deadline has passed, Cisco said it will decide whether to extend or withdraw the offer.For the full story, see Cisco finds Tandberg shareholders a tough crowd.
