Suppress Q.850 Reason headers for this endpoint
Do not forward 183 when it doesn't contain SDP
Configuration Option Descriptions
Asterisk will send unsolicited MWI NOTIFY messages to the endpoint when state changes happen for any of the specified mailboxes. More than one mailbox can be specified with a comma-delimited string. app_voicemail mailboxes must be specified as mailbox@context; for example: mailboxes=6001@default. For mailboxes provided by external sources, such as through the res_mwi_external _mwi module, you must specify strings supported by the external system.
This option only applies if media_encryption is set to
It can be one of the following values:
no- meaning no verificaton 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.
Some devices can't accept multiple Reason headers and get confused when both 'SIP' and 'Q.850' Reason headers are received. This option allows the 'Q.850' Reason header to be suppressed.
Certain SS7 internetworking scenarios can result in a 183 to be generated for reasons other than early media. Forwarding this 183 can cause loss of ringback tone. This flag emulates the behavior of chan_sip and prevents these 183 responses from being forwarded.
Configuration Option Reference
This option applies when an external entity subscribes to an AoR for Message Waiting Indications. The mailboxes specified will be subscribed to. More than one mailbox can be specified with a comma-delimited string. app_voicemail mailboxes must be specified as mailbox@context; for example: mailboxes=6001@default. For mailboxes provided by external sources, such as through the res_mwi_external _mwi module, you must specify strings supported by the external system.

The order by which endpoint identifiers are processed and checked. Identifier names are usually derived from and can be found in the endpoint identifier module itself (res_pjsip_endpoint_identifier_*). You can use the CLI command "pjsip show identifiers" to see the identifiers currently available.
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.
When Asterisk generates a challenge, the digest realm will be set to this value if there is no better option (such as auth/realm) to be used.

Enable/Disable ignoring SIP URI user field options.

Trigger scope for taskprocessor overloads
Advertise support for RFC4488 REFER subscription suppression
Configuration Option Descriptions
The caller-id and redirecting number strings obtained from incoming SIP URI user fields are always truncated at the first semicolon.
This option will cause Asterisk to place caller-id information into generated Contact headers.
This option specifies the trigger the distributor will use for detecting taskprocessor overloads. When it detects an overload condition, the distrubutor will stop accepting new requests until the overload is cleared.
global- (default) Any taskprocessor overload will trigger.
pjsip_only- Only pjsip taskprocessor overloads will trigger.
none- No overload detection will be performed.
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.
