To configure a PPTP VPN, you need to ensure that TCP port 1723 is open for communication. Additionally, the GRE protocol (IP protocol 47) must also be allowed through any firewalls, as it is required for the actual data transfer within the VPN. Proper configuration of both the port and protocol is essential for establishing a successful PPTP VPN session.

Symmetric Session-Key Protocol
To provide a secure CLI session with encryption to a Cisco switch an SSH or Secure Shell connection will be required as this uses a cryptographic network protocol that provides secure data communication.
The Session Initation Protocol (SIP) H.323
SIP, SI Protocol, or Session Initiation Protocol is a signalling protocol used in video or voice calls, Instant Messaging (IM), file transfer and online gaming over an Internet Protocol (IP). The main function of the SIP is to create, modify or terminate multicast or unicast sessions. i.e. The SIP is what starts up the video call or online game session or whatever.
A TCP session is a data transfer that takes place using the transmission control protocol. A session has three phases, connection establishment, data transmission, and connection termination.

NCP (Network Control Protocol) is responsible for negotiating and configuring the network-layer parameters of a PPP (Point-to-Point Protocol) session. It establishes and manages the network control options needed for the successful communication between the two endpoints of the PPP link. NCP allows for the customization of network protocols and parameters to suit the specific requirements of the PPP connection.
For a successful guided imagery session, individuals should select a quiet, relaxing location where there is a comfortable place to sit or recline
To get a SIP (Session Initiation Protocol) account, you typically need to sign up with a VoIP (Voice over Internet Protocol) service provider that offers SIP services. This involves selecting a plan, providing personal information, and sometimes verifying your identity. Once your account is set up, you'll receive SIP credentials, including a username, password, and server details, which you can use to configure your SIP-enabled devices or software.
