[Freeswitch-users] P-Asserted-Identity issue

Hello guys, i have a problem when i try to read P-Asserted-Identity header. Let's say i send to freeswitch this header: P-Asserted-Identity: <sip:123456789 at 192.168.0.73 <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users>:5060;user=phone> But when i try to read this header in my dialplan, i get: 123456789 When i check channel variables i see: variable_sip_P-Asserted-Identity: 370370370370 maybe there is a way to read full P-Asserted-Identity header? I need to resend this header without modifying it. Is it possible?
