Configuring AastraLink Pro 160 System and Network Parameters
Mobility Base Units (MBUs)
The AastraLink Pro supports the Aastra Mobility Base Unit 400, and the Aastra
420d DECT Handset. You can register up to 8 handsets with each MBU. The
MBU supports up to 3 SIP calls simultaneously.
Note: The PSTN port of the MBU is not currently supported when MBU400 is
configured by AastraLink - outbound PSTN calls will be routed via the
AastraLink FXO ports. The AastraLink does not support the use of the
RJ11 FXO interface on the MBU.
Multiple MBU 400 units can be added, identified by MAC address, and then
registered to the AastraLink Pro. Each registered handset receives a SIP extension
on AastraLink, including Web UI login and voicemail.
You can add MBU units to the AastraLink Pro using the Web UI at the location,
Configuration->VoIP->Mobility Base Units.
