SIP Header Modification help

I just need help with the Diversion header for FORWARDED calls.


Using SIP profile 101, the original Diversion header is stripped and replaced with the prefix.

This is a single number reach scenario.

voice class sip-profiles 101
request INVITE sip-header Diversion remove
request INVITE sip-header P-Asserted-Identity remove
request INVITE sip-header SIP-Req-URI modify "sip:00..(.*)@(.*)" "sip:\1@\2"
request INVITE sip-header To modify "<sip:00..(.*)@(.*)>" "<sip:\1@\2>"
request INVITE sip-header From modify "<sip:00..(..........)(.*)@(.*)>(.*)" "<sip:\2@\3>\4"
request INVITE sip-header Contact modify "<sip:00..(..........)(.*)@(.*)>(.*)" "<sip:\2@\3>\4"
request INVITE sip-header Remote-Party-ID modify "Remote-Party-ID:(.*)<sip:00..(..........)(.*)@(.*)>(.*)" "Diversion: <sip:\2@\4>\5"

If I use SIP Profile 400 it removes the header and doesn’t rewrite it, which gives me a Unknown Number calling to my cell phone (Sip 101 atleast gave the Original called party).

So that last line I need to have the remote party ID rewritten

3 REPLIES 3

Looks like sip profile 400 is applied to the outbound dial-peer and not sip profile 101. You can add the sip profile configuration to strip the DIVERSION header to the profile 400.

What does this line do?

request INVITE sip-header Remote-Party-ID modify "Remote-Party-ID:(.*)<sip:00..(..........)(.*)@(.*)>(.*)" "Diversion: <sip:\2@\4>\5"

My main problem is 101 is writing a header i dont want.  

This is replacing the RPID header with a diversion header with the values in the 2nd, 4th and 5th bracket of the remote-party-id (rpid)
