How to use
Install the AUDIOCODES MP-504 on a stable surface near power and network connections, then connect the 1 GbE Ethernet port to the local network and attach analog devices to the voice ports. Use the device management interface to configure SIP account credentials, network settings and codec priorities. Define call routing rules and any required dial plans to ensure proper handling of inbound and outbound calls. After saving and applying settings, test voice calls and fax transmission if applicable, and adjust jitter buffer or codec settings to optimize call quality.
Usage recommendations
For reliable operation, place the gateway on a network segment with Quality of Service (QoS) configured for voice traffic, keep firmware updated to the latest stable release, and perform initial tests using representative call scenarios.
