IP calls work when the devices are on the same network. To configure the IP call feature and port on the device web **Phone > Call Feature > Others** interface. ![akuvox-c315-indoor-monitor-administrator-guide-202209-image-nk9s4hiq.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/akuvox-c315-indoor-monitor-administrator-guide-202209-image-nk9s4hiq%281%29.png) **Parameter Set-up**: - **Direct IP**: enable the direct IP call if you do not allow direct IP calls to be made on the device. You can untick the check box to terminate the function. - **Direct IP Port**: the direct IP port is **5060** by default with the port range from **1-65535**. If you enter any values within the range other than **5060**, you are required to check if the value entered is consistent with the corresponding value on the device you wish to establish a data transmission with. ## 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. Click [here](https://knowledge.akuvox.com/docs/how-to-register-sip-server#register-sip-accounts) to view the SIP account registration example. To configure the SIP account on the device **More > Settings > Advance Settings > Account** screen. ![akuvox-c315-indoor-monitor-administrator-guide-202209-image-t22ildvb.jpg](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/akuvox-c315-indoor-monitor-administrator-guide-202209-image-t22ildvb%281%29.jpg) The parameter settings for SIP account registration can be configured on the **Account Setting** screen and they can also be configured on the device web interface. To perform the SIP account setting on the web **Account > Basic > SIP Account** Interface. ![图片.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/%E5%9B%BE%E7%89%87-1FAXBKG1.png) **Parameter Set-up**: - **Status**: Check to see if the SIP account is registered or not. - **Account**: Select Account1 or Account2. - **Active**: Check to activate the registered SIP account. - **Display Label**: Configure the device label to be shown on the device screen. - **Display Name**: Configure 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. To perform the SIP account setting on the web **Account > Basic > SIP Account** Interface. ![图片.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/%E5%9B%BE%E7%89%87-SJ4DK7MT.png) **Parameter Set-up**: - **Server IP**: Enter the server's IP address or its URL. - **Port**: Set up SIP server port for data transmission. - **Registration Period**: Set up SIP account registration time span. SIP re-registration will start automatically if the account registration fails during the registration time span. The default registration period is **1800**, ranging from **30-65535s**. ## Outbound Proxy Server configuration An outbound proxy server receives and forwards all requests the designated server. It is an optional configuration, but if set it up, all future SIP requests get sent there in the first instance. To configure the outbound proxy server on **Account > Basic > Outbound Proxy Server** interface. ![图片.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/%E5%9B%BE%E7%89%87-R1518X9L.png) **Parameter Set-up:** - **Server IP**: Enter the IP address of the outbound proxy server. - **Backup Server IP**: Set up backup server IP for the backup outbound proxy server. - **Port**: Enter the port number to establish a call session via the outbound proxy server or the backup one. ## SIP Call DND & Return Code Configuration The Do Not Disturb(**DND**) feature prevents unwanted incoming SIP calls, ensuring uninterrupted focus. It also allows you to set a code to be sent to the SIP server when rejecting a call. Path: **Phone > Call Feature > DND** ![图片.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/%E5%9B%BE%E7%89%87-KGCGXDI3.png) **Parameter Set-up**: - **DND**: Check the **Whole Day** or **Schedule** to enable the DND function. DND function is disabled by default. - **Schedule**: Enable the DND schedule for your indoor monitor. To configure a specific time to enable the DND feature. If you choose **Schedule** for DND, the **Whole Day** will be checked on the device. - **Return Code When DND**: Select what code should be sent to the calling device via the SIP server. 404 for Not Found; 480 for Temporarily Unavailable; 486 for Busy Here; 603 for Decline. ## Device Local RTP configuration Real-time Transport Protocol(**RTP**) lets devices stream audio and video data over a network in real time. To use RTP, devices need a range of ports. A port is like a channel for data on a network. By setting up RTP ports on your device and router, you can avoid network interference and improve audio and video quality. To set up device local RTP on web **Network > Advanced > Local RTP** interface. ![图片.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/%E5%9B%BE%E7%89%87-6UADD4NL.png) **Parameter Set-up**: - **Starting RTP Port**: enter the port value in order to establish the start point for the exclusive data transmission range. - **Max RTP port**: enter the port value in order to establish the end point for the exclusive data transmission range. ## Data Transmission Type Configuration Akuvox intercom devices support four data transmission protocols: **User Datagram Protocol(UDP)**, **Transmission Control Protocol(TCP**), **Transport Layer Security**(**TLS**), and **DNS-SRV**. To do this configuration on web **Account > Basic > Transport Type** interface. ![图片.png](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/%E5%9B%BE%E7%89%87-7Z4VHZPJ.png) **Parameter Set-up**: - **UDP**: select **UDP** for unreliable but very efficient transport layer protocol. UDP is the default transport protocol. - **TCP**: select **TCP** for a reliable but less-efficient transport layer protocol. - **TLS**: select **TLS** for secured and reliable transport layer protocol. - **DNS-SRV**: select **DNS-SRV** to obtain DNS record for specifying the location of services. And 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.
