If we setup the Snom phone manually, it is important to perform a factory reset after the UC edition firmware was installed. This step is re-stated in the Snom FAQ section.
Snom phone with the UC edition firmware successfully installed could be identified by:
- The phone display shows 'UC edition' when startup
- The WEB UI uses 443 instead of 80
- A menu item for Lync connection is added
To register the Snom UC edition phone to Elastix, we have to ensure:
- The rtp encryption in the sip section is disabled (it is enabled by default)
- The servertype is set to 'asterisk' in the sip section
- This field has been reset by UC edition firmware to OCS during the firmware upgrade and we have to change it to 'asterisk' to enable sip registration
