Feature Limitations
The Internet trunking application relies on the single call scenario, or a direct,
point-to-point call that does not terminate at multiple S8700 Multi-Connect nodes
through call processing.

Description
Abbreviated Dial strings with
embedded pauses lose digits
after the pause
Every IP trunk call goes
through A/D conversion,
which uses compression to
reduce bandwidth. Each
compression degrades the
voice signal and creates call
processing delay.
IP trunk's compression/
decompression cycle makes
ringback, busy and voice
detection
Calls extended across
multiple S8700 Multi-Connect
nodes require multiple call
paths. Significant voice
quality degradation is likely.
Recommendation
Most calls work. Do not create
Abbreviated dial strings with
embedded pauses.
No more than 3
compression/decompression
cycles for any call.
NOTE:
The compression/
decompression that most
voice mail systems use must
be counted as 1 cycle.
Do not administer these features:
Call Coverage Redirected
Off-Net (CCRON)
Certain wireless phone
coverage
Multiple call paths not
recommended
