Remote diagnostics will take care of most of your home electronics, but a few repairmen will still make house calls via video phone. 大部分家用電子設備將通過遠程診斷得到維修，但也有一些修理工作仍需要通過可視電話尋求上門服務。
For this reason, it is improper for a notarial agency to directly issue an official letter or allow notaries make a video telephone attestation at the request of a foreign court. 因此，公證處不宜應外國法院要求直接出具公函并由公證員在可視電話上作證。
