OptiPoint 600 SIP with Asterisk
The Siemens OptiPoint 600 SIP works quite well with Asterisk.
Creating and using a custom logo
Updating firmware / Switching from HFA to SIP
Sample configuration for use with Asterisk
Multi-line operation
Distictive ring using ALERT_INFO
WAP based phonebook
DHCP based configuration
Hints
- When logging is enabled on the phone, the phone becomes really slow
- The phone restarts on certain communication problems with the SIP server, check the phone’s SIP settings!
Open Questions
- Can the “SIP Session Timer” be used with Asterisk? It seems to be impossible to disable that feature, even though there is a check box: After saving the settings, the box is marked again.
- How can the LEDs next to the function keys be used as a Busy Lamp Field?
- How does MWI work?
- There seems to be an “autoanswer” function. How does it work?
Problems
- Phone needs to be restarted after major configuration changes, restarting takes > 2 Minutes
- Web interface has some glitches with non-IE browsers
- Hold/Unhold not functional
Wishes for future firmware revisions
- More control over backlight
- Possibility to assign a web/wap page to a function key
- Web browser (html)
