Indicate whether the module is activated.

A request/response enters module if the boolean filter evaluates to true. Ex: from.uri.domain contains 'sip.linphone.org', from.uri.domain in 'a.org b.org c.org', (to.uri.domain in 'a.org b.org c.org') && (user-agent == 'Linphone v2'). You can consult the full filter documentation here : https://wiki.linphone.org/xwiki/wiki/public/view/Flexisip/Configuration/Filter%20syntax/

List of whitespace separated domain names which the registar is in charge of. It can eventually be the '*' (wildcard) in order to match any domain name.

Register users based on response obtained from a back-end server. This mode is for using flexisip as a front-end server to hold client connections but registeracceptance is deferred to backend server to which the REGISTER is routed.

Maximum number of registered contacts per address of record.

List of contact URI parameters that can be used to identify a user's device. The contact parameters are searched in the order of the list, the first matching parameter is used and the others ignored.

When supported by the client, assign a pub-gruu address to the client, returned in the response.

Maximum expire time for a REGISTER.

Minimum expire time for a REGISTER.

Set a value that will override expire times given by the REGISTER requests. A null or negative value disables that feature. If it is enabled, max-expires and min-expires will not have any effect.

File containing the static records to add to database on startup. Format: one 'sip_uri contact_header' by line. Example:
<sip:contact@domain> <sip:127.0.0.1:5460>,<sip:192.168.0.1:5160>

Timeout after which the static records file is re-read and the contacts updated.

Implementation used for storing the contact URIs of each address of record. Two backends are available:
 - redis : contacts are stored in a Redis database, which allows persistent and shared storage accross multiple Flexisip instances.
 - internal : contacts are stored in RAM. Of course, if flexisip is restarted, all the contact URIs are lost until clients update their registration.
The redis backend is recommended, the internal being more adapted to very small deployments.

Hostname or address of the Redis server.

Port of the Redis server.

ACL username used to authenticate on Redis. Empty to disable. Setting this but not `redis-auth-password` is a misconfiguration, and will be ignored.

Authentication password for Redis. Empty to disable. If set but `redis-auth-user` is left unset or empty, Flexisip will attempt to register in legacy mode.

When Redis is configured in master-slave, Flexisip will periodically ask which Redis instances are the slaves and the master. This is the period with which it will query the server. It will then determine whether is is connected to the master, and if not, let go of the connection and migrate to the master.
Note: This requires that all Redis instances have the same password. Otherwise the authentication will fail.

Tell if Flexisip should try to connect to Redis slaves if master went down. Can be disabled if slaves hostname info are on private network for example.

Sequence of proxies (space-separated) where requests will be redirected through (RFC3608)

Name of the custom Contact header parameter which is to indicate the expire time for chat message delivery.

If not zero, the expire time put in the 200 OK response won't be the one required by the user agent, but will be slightly modified by substracting a random value. The value given by this parameter is the maximum percentage of the initial expire that can be substracted.
If zero, no randomization is applied.
