Configuring Basic Sip Parameters - 3Com VCX v7111 Installation Manual

The preferred coder is the coder that the VCX V7111 uses as a first choice for all
connections. If the far end gateway does not use this coder, the VCX V7111
negotiates with the far end gateway to select a coder that both sides can use.
Map outgoing calls to IP addresses (when Gatekeeper isn't used) by completing these
5
steps:
Click the arrow button next to the 'Tel to IP Routing Table' label; the 'Tel to IP
Routing' screen opens.
Any telephone number whose destination number matches the prefix defined in the
'Destination Phone Prefix' field and whose source number matches the prefix defined
in the adjacent 'Source Phone Prefix' field, is sent to the IP address entered in the 'IP
Address' field.
Click the Submit button; the 'Tel to IP Routing' table is automatically updated.
Click the Close Window button.
For more information on the 'Tel to IP Routing' table see the VCX V7111 H.323 user
manual.
Allocate VCX V7111 endpoints (analog lines) and their corresponding phone numbers to
6
incoming IP calls by completing these steps:
Click the arrow button next to the 'Endpoint Phone Number' label; the 'Endpoint
Phone Numbers' screen opens.
Enter the number of a channel, starting with 1, (or a group of channels), under the
'Channel(s)' column (for example 1-4 for the first 4 endpoints).
Assign each channel a phone number (for a group of channels, define the first
number in an ordered sequence). For an example of connecting two VCX V7111
8FXS devices, see Example of Connecting Two 8FXS Devices on page 39.
Click the Submit button; the 'Endpoint Phone Number' table is automatically
updated.
Click the Close Window button.
Click the Reset button and click OK in the prompt; The VCX V7111 applies the changes
7
and restarts. This takes approximately 1 minute to complete. When the VCX V7111 has
finished restarting, the Ready and LAN LEDs on the front panel are lit green.
H.323 users should continue with "Example of Connecting Two 8FXS Devices" on
page 39.
