Insecure
Specifies how to handle connections with peers. Default no (authenticate all
connections).
Dtmfmode
The DTMF signaling mode used by this device, usually rfc2833 for most phone.
Trustrpid
Whether Asterisk should trust the RPID settings from this device. Usually should be yes
for CONNECTEDLINE( ) functionality to work if supported by the endpoint.
Sendrpid
Whether Asterisk should send RPID (or PAI) info to the device. Usually should be
enabled to the settings used by your device for CONNECTEDLINE( ) functionality to
work if supported by the endpoint.
Prack
The PRACK request plays the same role as ACK, but for provisional responses.
Transport
This sets the allowed transport settings for this device and the default (Primary) transport
for outgoing. The default transport is only used for outbound messages until a
registration takes place. During the peer registration the transport type may change to
another supported type if the peer requests so. In most common cases, this does not have
to be changed as most devices register in conjunction with the host=dynamic setting. If
you are using TCP and/or TLS you need to make sure the general SIP Settings are
configured for the system to operate in those modes and for TLS, proper certificates have
been generated and configured. If you are using websockets (such as WebRTC) then you
must select an option that includes WS
Avpf
Whether to Enable AVPF. Defaults to no. the WebRTC standard has selected AVPF as
the audio video profile to use for media streams. This is not the default profile in use by
Asterisk. As a result the following must enabled to use WebRTC.
Icesupport
Whether to Enable ICE Support. Defaults to no. ICE (Interactive Connectivity
Establishment) is a protocol for Network Address Translator(NAT) traversal for
UDP-based multimedia sessions established with the offer/answer model. This option is
commonly enabled in WebRTC setups
Dtlsenable
Whether to Enable DTLS for this peer. Defaults to no.
Dtlsverify
Whether to verify that the provided peer cerificate is valid. Defaults to no.
Dtlssetup
Behavior on DTLS incoming and outgoing connections. Defaults to actpass.
Dtlscertfile
Path to certificate file to present
Dtlscafile
Path to cafile file to present
Dtlsprivatekey
Path to private key for certificate file.
Encryption
Whether to offer SRTP encrypted media (and only SRTP encrypted media) on outgoing
calls to a peer. Calls will fail with HANGUPCAUSE=58 if the peer does not support
SRTP. Defaults to no.
Asterisk Trunk Dial
Options
Asterisk Dial command options to be used when calling out this trunk. To override the
Advanced Settings default, check the box and then provide the required options for this
trunk.
Continue if Busy
Normally the next trunk is only tried upon a trunk being ‘Congested’ in some form, or
unavailable. Checking this box will force a failed call to always continue to the next
configured trunk or destination even when the channel reports BUSY or INVALID
NUMBER.
