Enabling Hop Off for Tie Trunks
When selected, this function allows calls over T1 tie trunks to use PSTN
trunks or other servers, when those trunks have been configured to accept
tie-trunk calls. For Hop Off to work, it must be enabled on all AltiServ
systems on which trunk calls are able to be used as a transit switch.
Outgoing
call on
PSTN Trunk
The call originating on System B hops off over the T1/PRI or VoIP trunk to use the PSTN
trunk in System A. Both System A and System B must be set up and configured to use
hop-off for tie-trunks.
Figure 12. Hop Off for Tie Trunks
The trunk configuration to allow this function is discussed under "Setting
General Trunk Attributes" on page 7-3.
The board must be configured to allow for tie trunks, as discussed in
"Setting up T1, PRI or E1 Channels on the Triton T1/PRI Board" on page
6-48.
Restricting Tie Trunk Calls
You can set call restrictions on tie trunk calls by telling the system to use
the same restrictions as the ones set up for an extension. Using the Call
restriction follows extension drop-down list, you can select the extension
with the restrictions to use for the tie trunk calls.
Setting 10-Digit Dialing Area Codes
The 10-Digit Dialing Area Code field lets you list area codes that do not
require dialing a "1" before the area code. To enter an area code, click the
Add button.
Note:
Applies only to calls that use a trunk access code. For calls using a
route access code, 10-digit dialing area codes need to be
configured in the Out Call Routing Configuration window, Dialing
Pattern page. See "Setting Dialing Pattern Routing" on page 8-6.
