What is CSeq?
CSeq. The CSeq header field is a required header field in every request. It contains a decimal number that increases for each request. Usually, it increases by 1 for each new request, with the exception of CANCEL and ACK requests, which use the CSeq number of the INVITE request to which it refers.

What is Max forward header in SIP?
The Max-Forwards header limits the number of times a request can be forwarded on its way to the recipient. The number is reduced by one each time the request is forwarded. The Max-Forwards header prevents a request from endlessly circling the SIP network if the recipient cannot be found. The default value is 70.
What does SIP P-charge-Info header support-Cisco?
The support for the SIP P-Charge-Info Header feature allows the Cisco BTS 10200 Softswitch to convey the charge party information of a call. Note This implementation is based on the IETF document: P-Charge-Info—A Private Header (P-Header) Extension to the Session Initiation Protocol (SIP) draft-york-sipping-p-charge-info-08.
What is the P called party ID header in 3GPP SIP?
RFC 3455 3GPP SIP P-Header Extensions January 2003 4.2 The P-Called-Party-ID header A proxy server inserts a P-Called-Party-ID header, typically in an INVITE request, en-route to its destination. The header is populated with the Request-URI received by the proxy in the request.
When to use P-charging-vector header in SBC core?
A P-Charging-Vector header is used to correlate the charging records generated by different entities on the path of the call. To include the information of the transit carriers for charging purposes, The P-Charging-Vector header can also carry a new parameter transit-IOI, if the transit carriers are involved in a call.
What are the private headers in SIP 4.1?
4. SIP Private Headers 4.1 The P-Associated-URI header This extension allows a registrar to return a set of associated URIs for a registered address-of-record. We define the P-Associated-URI header field, used in the 200 OK response to a REGISTER request.
