3. Add trunks to the Mobile-trunk Member List from the Not Member List by se-
lecting the channels and clicking the Left Arrow button. You can use the Shift key or
Ctrl key to select multiple channels.
You need to assign a Group ID to the channels. This Mobile Trunk Group ID allows
you to differentiate MobileExt users connecting through different trunk types, like
PSTN, SIP, or cell phone gateway. You can assign a mobile extension to use a spe
-
cific trunk group. For example, if you assign SIP trunk channels from 1-3 to Group
001, and mobile extension 237 is assigned to Group 001, then when you make a
call to Ext 237, only the SIP Trunk channels from 1-3 can be seized. If all three
channels are busy, the call will fail while other mobile extensions using another
mobile trunk group ID may not be impacted.
Mobile extensions are assigned to a group in the ExtensionAnywhere Configuration
dialog box (see Figure 116 on page 231).
Note: If a PRI span is used, only the whole span can be added or removed, not
individual PRI channels. T1 and analog trunks are added or removed
individually.
Although a whole PRI span is added, if Mobile Trunk Allocation is selected
as Shared (see Figure 116 on page 231), individual trunks, when idle, still
can be used dynamically by normal PRI trunk traffic or mobile extensions.
