Item Description
SIP Listening Transport
Layer Protocol
•
UDP
—Specify UDP as the transport layer protocol for incoming SIP calls and
enables UDP listening port 5060.
•
TCP
—Specify TCP as the transport layer protocol for incoming SIP calls and
enables TCP listening port 5060.
•
TLS
—Specify TLS as the transport layer protocol for incoming SIP calls and
enables TLS listening port 5061. If you select this option, you must select a
certificate from the
Certificate
list.
By default, both the UDP and TCP listening ports are enabled, and the TLS listening
port is disabled.
Configure this item in either of the following scenarios:
•
If the device is the call receiver, you must enable the listening port of the
transport layer protocol used by the incoming calls.
•
If TCP or TLS is selected as the transport layer protocol when the device initiates
a call, you must specify it as the SIP listening transport layer protocol in this item.
Otherwise, no register request can be initiated.
Resetting the setting for this item deletes the established connections.

Configuration item
Item Description
Media Protocol
•
RTP
—Specify the Real-time Transport Protocol (RTP) as the media flow protocol
for SIP calls.
•
SRTP
—Specify the Secure Real-time Transport Protocol (SRTP) as the media flow
protocol for SIP calls.
By default, the RTP protocol is applied.
When both the RTP and SRTP protocols are specified as the media flow protocols
for SIP calls:
•
If the device is the call initiator, both two media flow protocols are carried in the
INVITE message for the receiver to select.
•
If the device is the call receiver, the SRTP protocol is first used for media flow
negotiation. If the negotiation fails, the RTP protocol is used.
