You must then locate the proper parameter to modify and change its
value. Most of the parameters will require that you reboot the
AT-VP504E FXS communication unit. A reboot may be software-
initiated or manually initiated with the power connector. It will delete all
statistics stored and will overwrite all volatile parameter values in the
configuration file. A reboot will also reinitiate the entire unit’s initial
provisioning sequence.
Switching
Protocols
The MIB structure contains three MIB modules, but only two are
actually used at the same time:
With the SIP signalling protocol: the AT-VP504E FXS
uses the Provisioning MIB and SIP MIB.
With the MGCP signalling protocol: the AT-VP504E FXS
uses the Provisioning MIB and MGCP MIB.
You can switch between protocols and the proper MIB will be activated
upon restart.
To switch MIB according to the protocol used:
1. In the general Provisioning MIB, locate the signaling
ProtocolsSwitch
variable under the signaling
ProtocolsGroup
.
This variable allows you to switch from one protocol to
another.
2. Set the signalingProtocolsSwitch variable to either 0=MGCP
or 1=SIP
The default value is 1=SIP. The AT-VP504E FXS
communication unit reboots automatically. After the unit
restarts, it will use the selected MIB. See:
• “Part 2: SIP-Specific Settings” on page 83
• “Part 3: MGCP-Specific Settings” on page 107
