Operation
You can use all available mobile numbers and user names from within one
telephone or application. That means that you can handle all your
subscribed numbers from one device. Note that not all devices might
support subscribing to more than one line. See the device's user manual for
details.
Suitable telephones for this service are dedicated stand-alone VoIP-, IP- or
SIP-telephones, or soft-phone applications running on a PC or mobile
phone. A VoIP-app on a mobile phone can only be used if the phone is
connected to the device via a separate wireless router. Any modern SIP-
telephone or software are suited for use with the SAILOR 4300 unit, though
this cannot be guaranteed for a specific type of device or software.
At least the following protocols and codecs must be supported:
Note
For details of how to configure your device consult the
telephone's user manual.
Important
You cannot register more than one telephone on the same
mobile number respective user name on the SIP-server. If
more telephones register with the same SIP-profile, only the
last telephone registered will be subscribed to the mobile
number and be able to use this number for receiving and
making calls.
