3. Add trunks to the Mobile-trunk Member List from the Not Member List by
selecting the channels and clicking the Left Arrow button. You can use the Shift key
or Ctrl key to select multiple channels.
When you add channels to the
Mobile-trunk Member List , a dialog box opens:
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
specific 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 113 on page 237).
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 (see Figure 113 on page 237)), individual trunks, when idle,
still can be used dynamically by normal PRI trunk traffic or mobile extensions.
