When enabled the UDPTL stack will use IPv6.
If media_address is specified, this option causes the UDPTL instance to be bound to the specified ip address which causes the packets to be sent from that address.
It can be one of the following values:
no- meaning no verificaton verification is done.
fingerprint- meaning to verify the remote fingerprint.
certificate- meaning to verify the remote certificate.
yes- meaning to verify both the remote fingerprint and certificate.
Enable STIR/SHAKEN support on this endpoint. On incoming INVITEs, the Identity header will be checked for validity. On outgoing INVITEs, an Identity header will be added.
A STIR/SHAKEN profile that is defined in stir_shaken.conf. Contains several options and rules used for STIR/SHAKEN.
For outgoing authentication (asterisk is the UAC), the realm must match what the server will be sending in their WWW-Authenticate header. It can't be blank unless you expect the server to be sending a blank realm in the header. You can't use pre-hashed paswords passwords with a wildcard auth object. You can generate the hash with the following shell command:
For outgoing authentication (asterisk is the UASUAC), this must either be the realm the server is expected to send, or left blank or contain a single '*' to automatically use the realm sent by the server. If you have multiple auth object objects for an endpoint, the realm is also used to match the auth object to the realm the server sent.

The timeout (in milliseconds) to set on WebSocket connections.
Allow this transport to be reloaded.
Allow use of wildcards in certificates (TLS ONLY)
Use the same transport for outgoing requests as incoming ones.
If a websocket connection accepts input slowly, the timeout for writes to it can be increased to keep it from being disconnected. Value is in milliseconds; default is 100 ms.
Allow this transport to be reloaded when res_pjsip is reloaded. This option defaults to "no" because reloading a transport may disrupt in-progress calls.
In combination with verify_server, when enabled allow use of wildcards, i.e. '.' in certs for common,and subject alt names of type DNS for TLS transport types. Names must start with the wildcard. Partial wildcards, e.g. 'f.example.com' and 'foo..com' are not allowed. As well, names only match against a single level meaning '.example.com' matches 'foo.example.com', but not 'foo.bar.example.com'.

Outbound proxy used when sending OPTIONS request
Enables Path support for REGISTER requests and Route support for other requests.
The rewrite_contact option registers the source address as the contact address to help with NAT and reusing connection oriented transports such as TCP and TLS. Unfortunately, refreshing a registration may register a different contact address and exceed max_contacts. The remove_existing option and remove_unavailable options can help by removing either the soonest to expire or unavailable contact(s) over max_contacts which is likely the old rewrite_contact contact source address being refreshed.
This should be set to
The effect of this setting depends on the setting of remove_existing.
If remove_existing is set to
no (default), setting remove_unavailable to
yes will remove only unavailable contacts that exceed _max_contacts_to allow an incoming REGISTER to complete sucessfully.
If remove_existing is set to
yes, setting remove_unavailable to
yes will prioritize unavailable contacts for removal instead of just removing the contact that expires the soonest.
See remove_existing and max_contacts for further information about how these 3 settings interact.

The interval (in seconds) to send keepalives to active connection-oriented transports.

When Asterisk generates an outgoing SIP request, the From header username will be set to this value if there is no better option (such as CallerID) to be used.

Warning title Warning
The "none" and "pjsip_only" options should be used with extreme caution and only to mitigate specific issues. Under certain conditions they could make things worse.
Allow Asterisk to send 180 Ringing to an endpoint after 183 Session Progress has been send. If disabled Asterisk will instead send only a 183 Session Progress to the endpoint. (default: "no")
