Local portSIP – set the local port for SIP signalling. A change of this parameter will not be applied until the device is restarted. The default value is 5060. PRACK Enabled – enable the PRACK method (reliable confirmation of SIP messages with codes 101–199). REFER Enabled – enable call forwarding via REFER. Send Keep Alive Packets – set that the device shall inquire periodically about the state of the called station via SIP OPTIONS requests during the call (used for station failure detection during the call). IP Address Filter Enabled – enable blocking of SIP packet receiving from addresses other than the SIP Proxy and SIP Registrar ones. Primarily used for higher communication security and preventing unauthorised phone calls. Receive encrypted calls only (SRTP) – set that SRTP encrypted calls shall only be recieved on this account. Unencrypted calls shall be rejected. At the same time, TLS is recommended as the SIP transport protocol for higher security. Encrypted outgoing calls (SRTP) – set that outgoing calls shall be SRTP encrypted on this account. At the same time, TLS is recommended as the SIP transport protocol for higher security. Do not play incoming early media – disable playing of the incoming audio stream before the call sent by some PBXs or other devices is picked up (early media). A standard local ringtone is played instead. QoS DSCP Value – set the SIP packet priority in the network. The set value is sent in the TOS (Type of Service) field in the IP packet header. Enter the value as a decimal number. The change will be applied after the device restart.

****** Page 44 ****** 2N TELEKOMUNIKACE a.s., 2n.cz 44/90 External IP Address – set the public IP address or router name to which the device is connected. If the device IP address is public, leave this parameter empty. Starting RTP Port – set the initial local RTP port in the range of 64 ports used for audio and video transmission. The default value is 4900 (i.e. the range is 4900– 4963). The parameter is shared by both the SIP accounts and is set for account 1 only. RTP Timeout – set the audio stream RTP packet receiving timeout during the call. If this limit is exceeded (RTP packets are not delivered), the call will be terminated by the device. Enter 0 to disable this parameter. The parameter is shared by both the SIP accounts and is set for account 1 only. Calls General Settings – set the call duration limit after which the call is automatically terminated. The intercom signals termination with a beep 10 s before the call end. Enter any DTMF character into the call (# on your IP phone, e.g.) to extend the call time. Call Answering Mode (SIP1, SIP2) – set the way of receiving incoming calls. The following three options are available: Always busy – the device rejects incoming calls. Manual answering – the device signals incoming calls by ringing and the user can answer the call using a numeric keypad. Automatic – the device picks up incoming calls automatically. You can set the call receiving mode for each SIP account separately. Pick up in – this parameter is only active when the Automatic parameter pickup mode is enabled. The call is picked up automatically after the preset timeout. Time Limited DND Mode – disable ringing for a limited time. If this temporary silent mode is activated, the 2N IP intercom shall not ring when a call comes until timeout.

****** Page 45 ****** 2N TELEKOMUNIKACE a.s., 2n.cz 45/90 Ringing Time – set the maximum call setup and ringing time in which all Limit outgoing calls are automatically terminated. If the calls are routed to the GSM network via GSM gateways, you are advised to set a value longer than 20 s. Minimum value: 1 s, maximum value: 600 s. Set 0 to disable the time parameter. Audio Enable/disable the audio codecs offered for call setup and set their priorities. The tab below helps you define how DTMF characters shall be sent from the intercom. Check the DTMF receiving options and settings of the opponent to make the function work properly. In-Band (Audio) – enable the classic method of sending DTMF in the audio band using standardised dual tones. RTP (RFC-2833) – enable sending DTMF via the RTP according to RFC-2833. SIP INFO (RFC-2976) – enable sending DTMF via SIP INFO messages according to RFC-2976.
