See voice support on SLMS devices for information about voice support on SLMS devices.

1. Configure system voice settings

Before configuring a voice connection, you may need to configure system voice settings in the Configuration / Voice / System screen.

You may also need to modify voice settings in the Configuration / Advanced / Voice Signaling screen, depending on the country your device is operating in.

2. Configure VOIP server settings

In the Configuration / Voice / VOIP Servers screen, configure the VOIP servers:

Additional settings for SIP

After setting up the VOIP server, create a SIP dial plan in the Configuration / Voice / SIP PLAR / SIP Plan screen.

Additional settings for MGCP

MGCP supports redundant servers. To create redundant MGCP servers, in the Configuration / Voice / VoIP Servers screen, add a Secondary Server address.

3. Create voice connections

POTS subscribers are connected to VoIP remote endpoints created in the Configuration / Voice / SIP PLAR / Connections screen.

Configuring ESA

VoIP ESA cluster requires an ESA SIP dialplan in each of the SLMS devices that participate in the ESA cluster. For each ESA dialplan, enter the IP addresses of the desired system in the Configuration / Voice / SIP PLAR / SIP Dial Plan screen and change the Dial Plan Type to ESA. Also, if desired, change the Destination Name to the target device.

When in ESA mode, the system sequentially checks the configured dialplans for a matching string starting with the lowest number to the highest number dialplan. If a match is found, the call connection process is initiated immediately. If a match is not found, the next sequential dialplan is checked until all configured dialplans have been checked. Calls with unmatched strings are then terminated. It is recommended to configure lower number dialplans for more frequently called nodes and higher number dialplans for less frequently called nodes.
