Yesterday I tested Nokia770 and N800 as IP phones for LinuxMCE. I used Internet Communications Software for that. N800 was flashed by the latest OS2008 which already included it from the box. so, I just add a generic phone in LinuxMCE and setup a new SIP account on N800. After quick reload of router N800 connected to the Asterisk.
For Nokia770 I use OS2007 Hacker Edition. So, I followed by instructions from Internet Communications Software site and installed it successful regardless of the fact that the last package gave error. Finally, I added another generic phone to the LinuxMCE and configure SIP account on the Nokia770. After that I make a call from N800 to Nokia770. The quality of sound was good except a small echo (remember, I didn’t modify any options of Asterisk). But generally it was acceptable.
It’s really nice option to use Nokia770 or N800 as a SIP phone with Asterisk. But it’d be much better to integrate it into Orbiter. Maybe somebody knows howto do it.
