![]() ![]() ![]() Some email providers have security filters that prevent users from receiving or viewing large attachments, from receiving scheduled emails and similar. Register with server every – Set how often you want the device to register with the SIP server for the existing SIP accounts.ĭTMF payload type – Changes the default payload type for DTMF. The reason for switching is to avoid fragmentation, and the switch can take place if a request is within 200 bytes of the maximum transmission unit (MTU) or larger than 1300 bytes.Īllow via rewrite – Select to send the local IP address instead of the router's public IP address.Īllow contact rewrite – Select to send the local IP address instead of the router's public IP address. UDP-to-TCP switching – Select to allow calls to switch transport protocols from UDP (User Datagram Protocol) to TCP (Transmission Control Protocol) temporarily. ![]() Under Additional, select additional options. Under Audio, select at least one audio codec with the desired audio quality for SIP calls. Use NAT traversal when the device is connected to the network from behind a NAT router or a firewall. Under NAT traversal, select the protocols you want to enable for NAT traversal. Some firewalls might block RTP traffic on certain port numbers. The default start port for media transport is 4000. RTP start port – Enter the port used for the first RTP media stream in a SIP call. Enter a different port number if required. ![]() The signaling traffic through this port is encrypted with Transport Layer Security (TLS). TLS port – The network port used for encrypted SIP communication. The signaling traffic through this port is non-encrypted. SIP port – The network port used for SIP communication. Under Call handling, set the timeout and duration for the call. To allow the device to receive incoming calls, select Allow incoming calls. Go to System > SIP > SIP settings and select Enable SIP. To better understand how P2P works, see Peer-to-peer SIP (P2PSIP).įor more information about setting options, see SIP. Having independent depth-cueing for surface (nearest-point) and interior (brightest-point) allows for more visualization possibilities.Use peer-to-peer when the communication is between a few user agents within the same IP network and there is no need for extra features that a PBX-server could provide. For both kinds, depth-cueing is turned off when set to zero (i.e.100% of intensity in back to 100% of intensity in front) and is on when set at 0 < n 100 (i.e.( 100 − n)% of intensity in back to 100% intensity in front). Interior Depth-Cueing works only on brightest-point projections. Surface Depth-Cueing works only on nearest-point projections and the nearest-point component of other projections with opacity turned on. Two kinds of depth-cueing are available: Surface Depth-Cueing and Interior Depth-Cueing. The trade-off for this increased realism is that data points shown in a depth-cued image no longer possess accurate densitometric values. The depth-cueing parameters determine whether projected points originating near the viewer appear brighter, while points further away are dimmed linearly with distance. Surface/Interior Depth-Cueing Depth cues can contribute to the three-dimensional quality of projection images by giving perspective to projected structures. ![]()
