Voice Mail

a. With Voice Mail, please take into account usage in conjunction with
Auto Attendant, e.g. the number of channels calculation and traffic,
also visa versa

Extensions

a. There may not be enough DTMF resources if a lot of SLTs on site. This
could result in no dial tone, leaving end users retrying repeatedly .
There are 32 DTMF resources available for the first chassis, 96, in total,
shared across all chassis.

Traffic performance

Trunks

a. . If all the trunks are located at the central system
i Central system could be overloaded because of BHCA exceeded
(when also a lot of extensions on the central node)
End User Experience: see BHCA exceeded
ii IPLA has a maximum of 128 resources, could be not enough for all
call conversions, particularly if IP trunks, IP extensions are used. End
User Experience: see Lack of IPLA resource
iii Are there enough DDI table entries (2000 is the limit) which could
also prevent any night modes from being possible

Operator

a. With a centralised operator, please take the network traffic calculation
into account, as well as IPLA resources
