If calls are to be made to a Call Server that does not
contain a Voice Compression Card or does not have a
Voice Compression Module connected it is
recommended that the this Intramodule Trunk is also
created.
If fax calls are to be made between two Call Servers
where compression is supported a Dial Plan entry
similar to the this example should be created within
each fax machine’s Dial Plan.
The DialTransparent
Action will allow calls to by-pass an Intramodule Trunk.
A call made via this Dial Plan entry does not consume a
compression channel. (For further information on Dial
Plans please refer to page 130.)
Installing a Voice Compression Card
A Voice Compression Card supports G.729a to compress up to 8 voice calls between two Call Servers. A
card must be fitted at both ends as follows:

Extension Numbering
Before connecting a Phone Module, P308 or IP Phone to the system as described in the following
sections it is worth considering what extension numbers are required for the Users automatically created
during the set up process.
Once a Phone Module/P308/IP Phone has registered
with the system each analogue port on the Phone
Module and P308 eg Port01, Port02 etc, or IP Phone
port, will be assigned to a User eg Extn2017, Extn2018
etc automatically created during the installation. Each
User will be given an extension number, eg 2017, 2018
etc.
