Polycom is introducing an upgrade to their entry level IP320 / IP330 telephones. The new models, dubbed the Soundpoint IP321 and IP331, will replace and are virtually identical the old. However they will feature more memory and processing power under the hood to accommodate the ever growing Polycom SIP stack. Ship date for the new phones should be sometime in late July. Rumors of an HD version being released in the near future have also been heard.
