I was at home looking for a phone for my office. It had to run on a Fritzbox 73xx and have a connector for a headset (Easy PC headset with RJ10 adapter). The GPX1450 fulfilled these requirements. However, the start-up with the Fritz box was not as easy as thought and gestalltet something "Tricky". So more buyers do not have to search through all the forums here the necessary settings. SIP as usual set (Fritz box and GXP1450). In addition, these settings must be made in the GXP1450: Profile x-> Network Settings -> NAT Traversal (STUN): Keep active (so you can hear the other party) Profile x-> Audio Einstelungen-> selection x: (so you can hear the ring tone)
The sound quality (noise is very low, no echo) is much better than I expected for the price range. Can the GPX1450, for all who do not need large "bells and whistles", recommended.
