Provider and PBX profiles

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

Only available if TLS is selected. 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.
