SIP Stack (sipStack)

Configuration for the SIP stack

Name Type Default Description

acceptNonUtf8Bytes

boolean

false

Accept byte sequences that are not encoded in UTF-8.

auto100OnInvite

boolean

true

The SIP container automatically sends a 100 response code when an INVITE request is received.

auto482OnMergedRequests

boolean

false

The SIP container automatically sends a 482 response code when a merged request is received. This behavior is defined in the SIP RFC 3261 Section 8.2.2.2.

commaSeparatedHeaders

string

A list of header fields that should be comma-separated. If there are multiple values of the same header, the headers are not duplicated and the value will be in the same header separated by a comma.

compactHeaders

  • API

API
Headers are sent according to JSR289 javax.servlet.sip.SipServletMessage.setHeaderForm(javax.servlet.sip.SipServletMessage.HeaderForm)
Always
Headers are always sent in compact form
