Article Summary

IP Call & IP Call Configuration

An IP call is a direct call between two intercom devices using their IP addresses, without a server or a PBX. IP calls work when the devices are on the same network.

Navigate to the web Phone > Call Feature > Direct IP interface.

SIP Call & SIP Call Configuration

Session Initiation Protocol(SIP) is a signaling transmission protocol used for initiating, maintaining, and terminating calls. 

A SIP call uses SIP to send and receive data between SIP devices, and can use the internet or a local network to offer high-quality and secure communication. Initiating a SIP call requires a SIP account, a SIP address for each device, and configuring SIP settings on the devices.

SIP Account Registration

Each device needs a SIP account to make and receive SIP calls. 

Akuvox intercom devices support the configuration of two SIP accounts, which can be registered under two independent servers.

Navigate to the web Account > Basic > SIP Account Interface.

Parameter Set-up:

  • Display Label: the device label to be shown on the device screen.

  • Display Name: the device’s name to be shown on the device being called to.

a. To register SIP account for Akuvox indoor monitors, obtain Register Name, Username, and Password from Akuvox indoor monitor PBX screen.
b. To register SIP account for third-party devices, obtain Register Name, Username, and Password from third-party service provider.

SIP Server Configuration

SIP servers enable devices to establish and manage call sessions with other intercom devices using the SIP protocol. They can be third-party servers or built-in PBX in Akuvox indoor monitor.

Navigate to the web Account > Basic > SIP Server interface.

a. To register SIP account for Akuvox indoor monitors, obtain Server IP and Server Port from Akuvox indoor monitor PBX screen.
b. To register SIP account for third-party devices, obtain Server IP and Server Port from third-party service provider.

Parameter Set-up:

  • Preferred SIP Server: the primary server IP address or its URL.

  • Alternate SIP Server: the backup SIP server IP address or its URL.

  • Port: the SIP server port for data transmission.

  • Registration Period: the SIP account registration time span. SIP re-registration will start automatically if the account registration fails during the registration time span. The registration period ranges 30-65535s with 1800 default.

Configure Outbound Proxy Server

An outbound proxy server is used to receive all initiating request messages and route them to the designated SIP server in order to establish a call session via port-based data transmission.

Navigate to the web Account > Basic > Outbound Proxy Server Interface.

Parameter Set-up:

  • Server IP: the SIP address of the outbound proxy server.
  • Port: the Port number for establishing a call session via the outbound proxy server.

Configure Data Transmission Type

Akuvox intercom devices support four data transmission protocols: User Datagram Protocol(UDP)Transmission Control Protocol(TCP), Transport Layer Security(TLS), and DNS-SRV.

Navigate to the web Account > Basic > Transport Type interface.

Parameter Set-up:

  • UDP: an unreliable but very efficient transport layer protocol. UDP is the default transport protocol.

  • TCP: a reliable but less-efficient transport layer protocol.

  • TLS: a secured and reliable transport layer protocol.

  • DNS-SRV: obtains DNS record for specifying the location of servers. SRV not only records the server address but also the server port. Moreover, SRV can also be used to configure the priority and the weight of the server address.
