Proxy server address
The SIP proxy is your VoIP provider's gateway server and the first SIP server, where the device
should send SIP requests and expects to receive requests.
¤
Enter the IP address or the (fully qualified) DNS name of your SIP proxy server (max. 74 char-
acters, 0 - 9, a - z, A - Z, -, ., _).
Examples:
10.100.0.45
or
sip.domain.net
or
sipproxy01.domain.net
Proxy server port
¤
Enter the port number of the first SIP server, where the device should send SIP requests and
expects to receive requests.
Range: 1-65535; Default:
5060
(for UDP/TCP),
5061
(for TLS)
DNS SRV SIP server redundancy lookup might provide a different server port which is used then.
Registration refresh time
¤
Enter the time intervals (in seconds) at which the phone should repeat the registration with
the VoIP server (SIP proxy). A request will be sent to establish a session. The repeat is required
so that the phone's entry in the tables of the SIP proxy is retained and the phone can there-
fore be reached. The repeat will be carried out for all enabled VoIP connections.
Values: 1 - 5 digits, > 0; Default:
600
seconds
Transport protocol
¤
Select between UDP, TCP and TLS.
Use SIP Security (SIPS)
Only if TLS is selected. SIPS enhances SIP with TLS/SSL encryption. Using SIPS makes it more diffi-
cult to listen in on the connection. Data is transmitted encrypted over the internet.
¤
Mark/unmark the check box to enable/disable the use of SIPS.
SRTP options
SRTP (Secure Realtime Protocol) is a security profile to ensure confidentiality, integrity, replay
protection and message authentication for audio-visual data transmission over IP-based
networks.
¤
Select which calls should be accepted:
UDP
(User Datagram Protocol) UDP is a non session-based protocol. UDP does not establish a
fixed connection. The data packets ("datagrams") are sent as a broadcast. The recipient is
solely responsible for making sure the data is received. The sender is not notified about
whether it is received or not.
TCP
(Transmission Control Protocol) TCP is a session-based transmission protocol. It sets up,
monitors and terminates a connection between sender and recipient for transporting
data.
TLS
(Transport Layer Security) TLS is a protocol for encrypting data transmissions on the
Internet. TLS is a superordinate transport protocol.
Secure Real Time Protocol
Security is activated for voice connections.
Accept non-SRTP calls
Insecure calls are accepted even when SRTP is activated.
