Session Initiation Protocol (SIP) is the most commonly used VoIP signalling protocol. Due to its scalability, cross-compatibility and open nature, SIP has become the protocol of choice for VoIP signalling. H.323 is another commonly used protocol.

Transport layer TCP/IP Protocols are TCP and UDP
A work environment can block VoIP mobile dialers by implementing network restrictions that prevent access to specific ports and protocols commonly used by VoIP services. Additionally, organizations may use firewalls and intrusion detection systems to monitor and restrict unauthorized traffic. Employing mobile device management (MDM) solutions can further help enforce policies that restrict the installation or use of VoIP applications on company devices. Lastly, user education and awareness can reinforce compliance with these restrictions.
The commonly used protocols are the TCP/IP protocol suite. This is a set of protocols that work together, not a single protocol.

There are several protocols that are used for VoIP. The SiP, or H.323 protocol can be used for signalling and to establish a connection. UDP/RTP packets then generally carry the actual voice stream.
IP Sec, SSL, TLS
Long distance telephone calls is used before VoIP.
The two that are most commonly used are called TCP and UDP.
They are commonly used to implement state machines and shift registers.
A VoIP card is a hardware component used to enable Voice over Internet Protocol (VoIP) communication by converting analog voice signals into digital packets for transmission over the internet. It is typically installed in a server or computer and can support multiple channels to handle simultaneous calls. VoIP cards are commonly used in telephony systems, allowing businesses to integrate traditional phone services with modern internet-based communication.
A deterministic MAC protocol gives guarantees on message delay and channel throughput. Schedule based MAC protocols, based on time synchronization among nodes, are currently used to implement deterministic MAC protocols.
