Request

URI Parameters

Name	Type	Is Required?	Description
id	string	Yes	Unique ID identifier of Trunk.

Data Attributes

Name	Type	Nullable	Is Required?	Description
priority	integer	No	Yes	The priority of this target host. DIDWW will attempt to contact the target trunk with the lowest-numbered priority; target trunk with the same priority will be tried in an order defined by the weight field. The range is 0-65535. See RFC 2782 for more details.
weight	integer	No	Yes	A trunk selection mechanism. The weight field specifies a relative weight for entries with the same priority. Larger weights will be given a proportionately higher probability of being selected. The range of this number is 0-65535. In the presence of records containing weights greater than 0, records with weight 0 will have a very small chance of being selected. See RFC 2782 for more details.
capacity_limit	integer	No	Yes	Maximum number of simultaneous calls for the trunk.
ringing_timeout	integer	No	Yes	After which it will be end transaction with internal disconnect code Ringing timeout if the call was not connected.
name	string	No	Yes	Friendly name of the trunk.
cli_format	string	No	Yes	RAW - Do not alter CLI (default). E164 - Attempt to convert CLI to E.164 format. Local - Attempt to convert CLI to Localized format. CLI format conversion may not work correctly for phone calls originating from outside the country of that specific DID.
cli_prefix	string	No	Yes	You may prefix the CLI with an optional + sign followed by up to 6 characters, including digits and #.
description	string	No	Optional	Optional description of the trunk.
configuration	One of sip_configurations , pstn_configurations ,	N/A	Yes	Trunk configuration complex object.

Name	Type	Nullable	Is Required?	Description
username	string	No	Mandatory	User part of R-URI in INVITE request. You also may use “{DID}” pattern which will be replaced by called DID number in E164 format. For example, you can set Username to “+{DID}”; if you wish to have it in +E164 format
host	string	No	Mandatory	Host part of R-URI in INVITE request.
auth_user	string	No	Optional	Optional authorization user for the SIP server.
auth_password	string	No	Optional	Optional authorization password for the SIP server.
auth_from_user	string	No	Optional	Specify user in a from field instead of CallerID (overrides CallerID). Some equipment require from; to be equivalent to Auth user.
auth_from_domain	string	No	Optional	Sets default from domain in SIP messages. Some equipment may require specific From Domain.
sst_refresh_method_id	integer	No	Optional	SIP method which will be used for session update. See RFC 4028 for more details. Possible values: 1 - Invite 2 - Update 3 - Update fallback Invite

dns_srv_failover_timer	integer	No	Optional	Invite transaction timeout for each of gateways with DNS SRV rerouting (Default 2000ms).
rtp_ping	boolean	No	Optional	Use RTP PING when connecting a call. After establishing the call, DIDWW will send empty RTP packet RTP PING. It is necessary if both parties operate in Symmetric RTP / Comedia mode and expect the other party to start sending RTP first.
rtp_timeout	integer	No	Optional	Disconnect the call if the RTP packets do not arrive within the specified time.
sst_min_timer	integer	No	Optional	Minimal SIP Session timer value (Default 600 seconds). See RFC 4028 for more details.
sst_max_timer	integer	No	Optional	Maximal SIP Session timer value (Default 900 seconds).. See RFC 4028 for more details.
sst_session_expires	integer	No	Optional	Session-Expires header value. Optional, should be in range with sst_min_timer and sst_max_timer.. See RFC 4028 for more details.
port	integer	No	Optional	Port part of R-URI in INVITE request (is not mandatory). If port is null, SRV record will be resolved (or A record if SRV is unavailable).
rx_dtmf_format_id	integer	No	Optional	The method id for receiving DTMF signals from customers equipment. Possible values: 1 - RFC 2833 2 - SIP INFO application/dtmf-relay OR application/dtmf 3 - RFC 2833 OR SIP INFO
tx_dtmf_format_id	integer	No	Optional	The method of sending DTMF signals to customers equipment. Possible values: 1 - Disable sending 2 - RFC 2833 3 - SIP INFO application/dtmf-relay 4 - SIP INFO application/dtmf
force_symmetric_rtp	boolean	No	Optional	Forced to work in Symmetric RTP / COMEDIA mode.
symmetric_rtp_ignore_rtcp	boolean	No	Optional	Avoid switching RTP session based on RTCP packet while working in Symmetric RTP / COMEDIA. Only RTP packets will be considered.
sst_enabled	boolean	No	Optional	Enable SIP Session timers customization. SIP session timers are used to make sure that a session (dialog) is still alive, even though there may have been a long time since the last in-dialog message. If the other end is not responding, the dialog will be hung up automatically. SIP session timers need to be supported by all end points for it to work. It’s a SIP extension, standardized by the IETF. See RFC 4028 for more details.
