This document is intended to provide the reader with information on how to use TCP on a LIP 1000i series phone for iPECS Cloud

 

 

LIP (1000i series only) Phone TCP Connection

1.) Please note that the iPECS Cloud platform LIP handsets use IPKTS (iPECS proprietary protocol) over UDP by default.

 

 2.) In cloud version 5 there is the option to enable TCP for registration of handsets. A TCP connection is slower than UDP but has more reliable packet delivery and packets that lost are attempted to be recovered. This is not the case when using UDP

 

3.) you will find the setting in: as per the image.

Why TCP:

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. A key difference between TCP and UDP is speed,

as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however,

retransmission of lost data packets is only possible with TCP

 

Why TCP is more reliable than UDP:
TCP is reliable as it guarantees the delivery of data to the destination router. The delivery of data to the destination cannot be guaranteed in UDP. TCP provides extensive error-checking mechanisms. It is because it provides flow control and acknowledgment of data.
