Trunk Selection
With some phone systems, incoming calls hunt from the beginning of a trunk group (trunk 1, trunk
2,...) for an available trunk, while outgoing calls hunt in reverse order (trunk 10, trunk 9, ...). Others
specify the first and second preference trunk groups for both incoming and outgoing calls. If a large
two-way trunk group is to be split, re-examine the PBX programming for outgoing trunk selection and
determine the trunk group to use for outgoing calls.

Ordering Phone System Changes
If your company is not the PBX provider, order changes from the PBX vendor on behalf of the
customer. Provide a Service Provider Letter (Figure 2-4) to the PBX vendor indicating the changes
needed to the PBX for the VP 300, and schedule the changes. If possible, try to use the PBX’s
terminology when requesting these changes. You may also want to provide them with information
from this chapter. Review the previous sections of this chapter for information to fill in the blanks.
Read over the letter and in particular, the footnotes. Depending upon the application, portions of the
letter may need to be expanded upon or deleted.
