We also installed a GrandStream phone recently with sipgate and I had the same problem in the beginning. Solution was, to disable STUN on the device and enable the sip helper modules (nf_nat_sip, nf_conntrack_sip) on the shorewall firewall. Only rule I made for the phone was an ACCEPT on all outgoing UDP connections (for your case: ACCEPT loc:192.168.10.160 net udp).
