Enabling/Disabling Optional “Allow” and “Allow-Event” Headers
Use the following procedure to enable/disable “Allow” and “Allow-Event” headers:
Configurable SIP P-Asserted Identity (PAI)
The BluStar 8000i support a private extension to SIP for Asserted Identity within trusted networks (as defined in RFC
3325). This feature allows a network of trusted SIP servers to assert the identity of authenticated users, and verify that
BluStar 8000i messages originate from a Trusted Identity. Upon receiving a message from a caller in the Trusted Network,
the BluStar 8000i reads the contents of the P-Asserted-Identity (PAI) header field and displays it on the BluStar 8000i UI.
The BluStar 8000is provide the ability for the administrator to enable or disable the display of PAI information on the
BluStar 8000i using the “
sip pai ” parameter in the configuration files.
Enabling/Disabling P-Asserted Identity (PAI)
Use the following procedure to enable/disable PAI:
Configurable Compact SIP Header
The BluStar 8000is provide a feature that allows an administrator to shorten the length of a SIP packet by using the com-
pact form. This feature is in accordance with Compact SIP Headers defined in RFC 3261.
For example, the following SIP header is the long format:
Via: SIP/2.0/UDP
10.50.91.2:5060;branch=z9hG4bK571ebe0c;rport=5060;received=10.50.91.2
From: "Unknown" <sip:Unknown@10.50.91.2>;tag=as19d00fc8
To: <sip:1106@10.50.110.54:5060;transport=udp>;tag=916699998
Call-Id: 73cad5456806f3a7768d17e8617279d7@10.50.91.2
CSeq: 102 OPTIONS
The following SIP header is equivalent to the above SIP header, however uses the short (compact) format instead:
v: SIP/2.0/UDP
10.50.91.2:5060;branch=z9hG4bK571ebe0c;rport=5060;received=10.50.91.2
f: "Unknown" <sip:Unknown@10.50.91.2>;tag=as19d00fc8
t: <sip:1106@10.50.110.54:5060;transport=udp>;tag=916699998
i: 73cad5456806f3a7768d17e8617279d7@10.50.91.2
CSeq: 102 OPTIONS
By default, the BluStar 8000i uses the long format. However, an administrator can provision the short (compact) format
using “
sip compact headers ” parameter in the configuration files.
