Qualify
Setting to yes (equivalent to 2000 msec) will send an OPTIONS packet to the endpoint periodically
(default every minute). Used to monitor the health of the endpoint. If delays are longer then the
quality time, the endpoint will be taken offline and considered unreachable. Can be set to a value
which is the msec threshold. Setting to no will turn this off. Can also be helpful to keep NAT
pinholes open.
Qualifyfreq
Frequency in seconds to send qualify messages to the endpoint.
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 message 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 certificate 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 SPTR 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.
Callgroup
Callgroup(s) that this device is part of, can be or more callgroups, e.g. ‘1,3-5’ would be in groups
1,3,4,5.
Pickupgroup
Pickupgroup(s) that this device can pickup calls from, can be one or more groups, e.g. ‘1.3-5’
would be in groups 1,3,4,5. Device does not have to be in a group to be able to pickup calls from
that group.
Allow
Allow specified codecs, the available codecs are on the left options bar and the selected on the
right.
Dial
How to dial device, this should not be changed unless you know what you are doing.
Accountcode
