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 IP Connect nodes
through call processing.

Table 8-293 describes the feature limitations for S8700
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 IP 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
