a - Call forward mode
0 - not in use
1 - On busy

Example: ChannelToFax3 = 1 (use port '3' only for Fax)
'IsFaxUsed' parameter should be set to '1' in order to use the H.323 Fax
according to Annex D T.38.
When channel is set to 2 (Voice + Fax), at beginning of a call, the logical channel
is opened as Voice channel, and after Fax detection, the channel is reopened as
Fax T.38 channel.
This parameter can appear up to 4 times.
Mapping phone number to IP address, using phone number prefix
Example: Prefix = 20,10.2.10.2
Any dialed number that starts with "20" is routed to IP address "10.2.10.2".
This parameter is needed when a Gatekeeper is not used.
