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 Avaya DEFINITY Server
nodes through call processing.
Table 329
describes the feature interactions for
Avaya MultiVantage Software.

Feature/
Performance Description
Recommendation
Abbreviated
Dialing
Abbreviated Dial strings with
embedded pauses lose digits
after the pause
Most calls work. Do not create
Abbreviated dial strings with
embedded pauses.
Compression
limitations
All IP trunk calls go through
A/D conversion, which uses
compression to reduce
bandwidth. Each
compression degrades the
voice signal and creates call
processing delay.
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.
Call Classifier
IP trunk’s compression/
decompression cycle makes
ringback, busy and voice
detection
Do not administer these features:
■
Call Coverage Redirected
Off-Net (CCRON)
■
Certain wireless phone
coverage
Call Coverage
Call Forwarding
Call Transfer
Calls extended across
multiple Avaya Definity
Server nodes require multiple
call paths. Significant voice
quality degradation is likely.
Multiple call paths not
recommended
