Hi Warren, Device A is behind NAT with regards to asterisk server. As far as localnet statement first I did configured localnet = 130.8.2.0/255.255.255.0 as per local network, after that made a SIP call and the message I'm getting is listed below;
[Feb 2 11:14:52] WARNING[23868]: chan_sip.c:3622 retrans_pkt: Retransmission timeout reached on transmission OGEzODA0MzI4MWE1NzdiZDlkNmQ3NjYyMzJjYzYyOTY. for seqno 1 (Critical Response) -- See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions Packet timed out after 6400ms with no response [Feb 2 11:14:52] WARNING[23868]: chan_sip.c:3651 retrans_pkt: Hanging up call OGEzODA0MzI4MWE1NzdiZDlkNmQ3NjYyMzJjYzYyOTY. - no reply to our critical packet (see https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions). So after setting to 130.0.0.0/130.0.0.0 I wasn't getting the above warning message but facing one way audio.
