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.
Figure 7. 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 or PRI Channels on the Triton T1/PRI Board” on page 6-39.
Restricting Tie Trunk Calls

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
