door station calls display panel or mobile App but cannot make a VoIP call to a telephone or Soft Phone. Non SIP IP systems are restricted to calling other devices within the same system i.e. At the most basic they may want to receive intercom calls to their mobile only which they can do through a VoIP call to the mobile number or to a VoIP App on the mobile phone. Home owners may find this useful too where they have (or want) a number of VoIP extensions in the home and want the intercom to make a video call to the phones as a group call or individual extensions or even call forward to a phone outside the system. This is especially attractive for businesses where they are likely to have an on premises IP PBX or a cloud hosted server and they want to integrate the intercom or camera into the existing business telephone server or move to a more cost effective IP PBX appliance solution rather than the expensive PABX systems used in the past. A CCTV camera could call a phone number when it detects movement in a defined area of the camera view. A door station could call a local display panel first and then try another number second and then a mobile number etc. In this way a SIP device can call other SIP devices much the same as making a phone call. They can also call devices via a SIP server as they have additional SIP accounts. The message is using SIP but as the devices are on the same network they can find each other without requiring a SIP server – this is unique to this system. the door station will call the intercom panels and normal intercom functionality will occur. Our intercoms sold as SIP systems (door station and display panel) will work without a SIP server i.e. Other equipment requires a SIP server to operate. So why should you consider a SIP based intercom or CCTV camera?įirstly not all SIP based equipment is the same.įor example, some equipment provides SIP as an additional function set and will work without connecting to a SIP server (IP PBX). SIP can also be found in many other systems such as online gaming, CCTV and security systems, FAX etc. SIP is the protocol used predominantly in all IP based telephony. The evolution of wireless broadband is also seeing mobile networks move to all IP based networks including telephony. With the rollout of the NBN in Australia all telephony will eventually be carried over the internet as VoIP. VoIP (voice over IP) uses SIP to communicate between devices and phone systems. SIP is used with IP telephone systems and other SIP devices. The UA then uses the account to make calls to other devices which are found on the IP network using standard IP network systems such as DNS.įor a more complete definition of SIP please check this link here: This is similar to the email system where an email account is a registered account on an email server. Typically, each end device (User Agent or UA) registers with a SIP server or IP PBX. SIP allows the seamless carriage of PSTN (standard telephone) and video conferencing and messaging on an IP network eg.
