12.7.Data Transmission Type Configuration
SIP message can be transmitted in three data transmission protocols: UDP
(User Datagram Protocol), TCP (Transmission Control Protocol), TLS
(Transport Layer Security) and DNS-SRV. In the meantime, you can also
identify the server from which the data come from. To do this configuration
on web Account > Basic > Transport Type interface.
Parameter Set-up:
 UDP: select “UDP” for unreliable but very efficient transport layer
protocol. UDP is the default transport protocol.
 TCP: select “TCP” for Reliable but less-efficient transport layer protocol.
 TLS: select “TLS” for Secured and Reliable transport layer protocol.
 DNS-SRV: select “DNS-SRV” to obtain DNS record for specifying the
location of services. And SRV not only records the server address but
also the server port. Moreover, SRV can also be used to configure the
priority and the weight of the server address.
