Abstract

The invention provides an SIP interphone and belongs to the technical field of intercommunication equipment, and specifically relates to an SIP interphone. The SIP interphone is convenient to use and has good conversation effect. The SIP interphone includes a network transformer, a network module, a POE power receiving module, a voltage conversion module, a switching quantity input interface, a switching quantity output interface, a VOIP chip and a sound card module. The structural elements of the SIP interphone are: a signal transmission port of the VOIP chip is connected with a signal transmission port and key interfaces of the network module, and a signal transmission port of the sound card module; a signal output port of the VOIP chip is connected with the switching quantity output interface through a first driving circuit; a signal input port of the VOIP chip is connected with the switching quantity input interface through a second driving circuit; and a power port of the VOIP chip is connected with an output port of the voltage conversion module.

Description

technical field [0001] The invention belongs to the technical field of intercom equipment, and in particular relates to a SIP intercom. Background technique [0002] The walkie-talkie is a two-way mobile communication tool. It can make calls without any network support, and there is no call charge. It is suitable for relatively fixed and frequent calls. There are currently three types of walkie-talkies: analog walkie-talkies, digital walkie-talkies, and IP walkie-talkies. The function of the existing walkie-talkie needs to be enhanced, the power supply mode is single, and it is not convenient to use. In addition, the power of existing walkie-talkies is not large enough, and the sound quality is not good enough. Contents of the invention [0003] The present invention aims at the above problems and provides a SIP walkie-talkie that is easy to use and has good call effect. [0004] In order to achieve the above object, the present invention adopts the following technical ...
