Narrative:
While on our polar routing; n75w080-n80w080-n85w090-dekmo-devid-badro-beson- edoni; we lost complete communication with [the] company for over 2 hours. We had no data link; satellite voice; and were totally unable to establish communication with commercial radio [and] tried many different frequencies with no success. Communication with gander was poor at best. We did have satisfactory communication with murmansk control once in their airspace. Once we were able to get data link and satellite voice back we contacted company (dispatch) to inform them that we had lost communication with them for over 2 hours and just checked to make sure everything was ok. We did everything possible to comply with fom requirements to maintain communication with the company. We were basically on our own if there was an emergency or would have been unable to communicate if company had tried to contact us with anything important.
