Problems with Cisco IP phones over IPSec

[dochy]

Hello everybody! I am using CUCM IP phone server in my office and Cisco Firepower as a main router. In remote office I am using pfsense as router and I build site to site IPsec VTI based VPN with Cisco Firepower. Problem is Cisco phones can't register over Pfsense IPsec firewall rules on both sides are open to any ports and local networks, I can ping from CUCM remote phone and vice versa. I tryed to packet capture from pfsense and I see that SIP TCP packets are transmissioning. My pfsense version is 2.7.2

Here 10.122.48.2 is CUCM server and 10.124.0.14 is Cisco Remote phone
