SIP TCP VS UDP
When making a VoIP call, the Session Initiation Protocol (SIP) is responsible for initiating and terminating the call. SIP can run over either the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP). SIP calls made over UDP are generally less expensive to set up and maintain than SIP calls made over TCP. SIP supports both TCP and UDP. Call Nation uses UDP by default, but you can switch to TCP if needed. Prepaid Mall uses TCP. When using Call Nation, you can switch to TCP if needed. Simply go to your settings and change the “transport” setting to TCP. Doing so may improve call quality or fix the connectivity issues you’re experiencing. Prepaid Mall uses TCP by default. This is because TCP is more reliable than UDP and ensures that your calls are always connected. However, you may experience some latency when using Prepaid Mall with TCP.

The main advantage of using UDP for SIP is that it is a simpler protocol than TCP. UDP is a “connectionless” protocol, which means that each SIP message is sent independently of any other SIP message. This makes UDP a good choice for SIP calls that do not need to be reliable, such as those made with Voice over IP (VoIP). Another advantage of using UDP for SIP is that it can be used with NAT (Network Address Translation). NAT is a technology that allows multiple devices on a private network to share a single public IP address. NAT is commonly used with home and small office networks.
As mentioned earlier, SIP can be carried over either TCP or UDP. There are benefits and drawbacks to using each protocol. UDP is the default protocol for SIP and is typically used for the initial setup of a SIP session. TCP is used for SIP signaling after the initial setup.SIP UDP is a connectionless protocol, which means that each SIP message is sent independently of other SIP messages. This can be both a benefit and a drawback. The main advantage of using UDP is that it is much simpler than TCP and requires less processing power. This can be important for SIP devices that have limited processing power, such as SIP phones.
