Signalling Protocol
Configuration – SIP
The AT-VP504E FXS uses SIP signalling programs and information
defined in a SIP stack to work properly. This includes SIP Log
information, server addresses, etc.
Setting up the SIP
Logging Client
The SIP Logging Client information is used to log the incoming and
outgoing SIP packets.
To enable SIP Logs:
1. In the SIP MIB, locate the sipUALogEnable variable (under
sipUALogGroup ).
This variable allows the stack to log SIP packets.
2. Set the sipUALogEnable variable to 1=Enable.
3. Set the IP port number for SIP User Agents in the sipUAPort
variable (under
sipUAGroup ).
The default port value is 5060.
DHCP vs. Static
Configuration
The SIP User Agents information can be assigned through a DHCP
server or set statically.
To use DHCP-assigned information:
1. In the SIP MIB, locate the sipUALogUseDhcp variable (under
sipUALogGroup ).
This variable defines whether the AT-VP504E FXS must ask
for its SIP Log settings through a DHCP server or not.
2. Set the sipUALogUseDhcp variable to 1=DHCP.
You can query the SIP Logging Client’s IP address and Port
number assigned by the DHCP server in the
sipUALogDhcp
Host
and sipUALogDhcpPort read-only variables.
3. Set the DHCP Vendor Specific code of the SIP Logging Client
in the
sipUALogDhcpVendorSpecificCode variable.
This code can be any number between 0 and 254. The
default value is 202.
