[Freeswitch-users] P-Asserted-Identity

Hi, I was looking in wireshark why some of the other providers are rejecting some of my calls. Some of our client are connected to Freeswitch via cabel-modem with voip support. I found that the problem appears when in sip header sip.P-Asserted-Identity is send and that FS send it to the SBC. The other softswith whitch is not FS and is working properly (this part), also get sip.P-Asserted-Identity in sip header but does not send it to sbc, it change it to P-Charge-info. Is it possbile to change that behaviour on FS so that other providers will not rejecting our calls? Thanks! Miha
