Configure various SIP parameters
This section is OPTIONAL
The header for this section is [sip]
| Name | Mandatory | Type | Default | Description |
|---|---|---|---|---|
| bind_address | no | string | any | The IP address that the SIP stack binds to. This is the IP that must be called into in order to reach BVR, however it must be an IP address that is defined to the system. "any" will listen on any IP address. Changing this option is useful if the system has multiple network adapters with different IP addresses and the administrator wishes to limit inbound calls to one of those adapters |
| presentation_address | no | string | auto | The IP address to present as the local address (affects "Contact" and "Via" headers). Overrides default_presentation_address in [general] |
| ignore_sent_by_check | no | boolean | false | Determines whether BVR ignores the SIP sent-by check |
| dns_servers | no | string array | Specifies which DNS server(s) to use for SIP communication. If one fails the number of times specified by dns_failure_threshold, it will move to the next in the list. If this option is not specified, the DNS servers used will be determined by the system's configuration in /etc/resolv.conf Note: This variable is an array of strings. Each item should be individually quoted and comma separated, with the entire variable surrounded by [] brackets. e.g. ["a", "b", "c"] | |
| dns_timeout | no | integer | 5000 | Specifies the timeout (in milliseconds) of a DNS request. If set to 0, DNS requests will have no timeout - this is not recommended, however, as it will not be possible to detect if a DNS server is failing. If this is not specified, the dns timeout will be determined by the timeout parameter in the system's configuration in /etc/resolv.conf Min: 0, Max: 30000 |
| dns_failure_threshold | no | integer | 2 | Specifies the number of times connection to a DNS server can fail before the next DNS server is used. If this is not specified, the threshold will be determined by the attempts parameter in the system's configuration in /etc/resolv.conf Min: 1, Max: 5 |
| dns_retry_interval | no | time | 1 second | This parameter was introduced in version 7.22.0 Specifies the amount of time to wait before retrying a DNS query if the last attempt returned no results This is a time unit value and can be written in human readable form (e.g. "1 day", "3 weeks" etc.) If just a number is supplied, it will be interpreted as MILLISECONDS Min: 0 milliseconds, Max: 20 years |
| user_sources | no | string array | ["To"] | Specifies where to get the "user" part of the SIP URI. This can one or more of "To", "Request_URI". Setting user_sources to both "To" and "Request_URI" allows the Blueworx Platform to check both sources, in the order defined, to find an application mapping. Note: This variable is an array of strings. Each item should be individually quoted and comma separated, with the entire variable surrounded by [] brackets. e.g. ["a", "b", "c"] |
| caller_id | no | string | bvr | This parameter is new in version 7.27.1 Caller Id used as SIP user for outbound SIP requests |
