I have configured the below access-list
access-list outside permit icmp any any
access-list outside permit udp any any
access-group outside in interface in outside
But from the below logging message it seems the inbound ICMP connection is not getting built up
%ASA-7-609001: Built local-host outside:10.3.1.1
%ASA-6-302020: Built outbound ICMP connection for faddr 10.3.1.1/0 gaddr 10.40.1.1/232 laddr 10.40.1.1/232

Here I can see outbound ICM connection from 10.40.1.1 to 10.3.1.1 but no inbound connection.
Traffic from 10.40.1.1 to 10.3.1.1 is a voice traffic.
Can someone suggest what is missing?
