The problem appear after I applied policy-map to Tunnel interface:

[..]
policy-map PM-Voice
 class CM-Voice
  priority 180 6400
 class class-default
  fair-queue
policy-map PM-Tunnel
 class class-default
  shape average 256000
  service-policy PM-Voice
[..]
interface Tunnel0
 bandwidth 256
 ip address 1.1.1.9 255.255.255.252
 ip mtu 1420
 
 service-policy output PM-Tunnel

 load-interval 30
 qos pre-classify
 tunnel source 1.10.1.10
 tunnel destination 1.10.1.16
 tunnel bandwidth transmit 256
 tunnel bandwidth receive 256
 crypto map VPN-GT

Could anybody assist in that issue?
