Our SIP provider has asked us to modify our outgoing SIP header INVITE messages to allow them to block CLI.
The section of the current SIP Header we need to modify looks like this;
Remote-Party-ID: "Test" <sip:+44xxxxxxxxxx@10.x.x.x>;party=calling;screen=no;privacy=off
We need to change privacy=off to privacy=full
I've created the following SIP profile but this does not change the SIP header, never had to modify SIP headers before so this is probably where the problem is;
voice class sip-profiles 1
request INVITE sip-header Remote-Party-ID modify "Remote-Party-ID:(.*>).*" "Remote-Party-ID:(.*>);party=calling;screen=no;privacy=full"
request REINVITE sip-header Remote-Party-ID modify "Remote-Party-ID:(.*>).*" "Remote-Party-ID:(.*>);party=calling;screen=no;privacy=full"
I have then applied this SIP profile to a dial-peer;
dial-peer voice 555 voip
description ** TEST **
max-conn 200
destination-pattern +44xxxxxxxxxx
max-bandwidth 18000
session protocol sipv2
session target ipv4:10.x.x.x:5060
voice-class sip asserted-id pai
voice-class sip profiles 1
dtmf-relay rtp-nte
If anyone out there has any experience of doing this I would really appreciate some assistance with this issue
