[asterisk-users] Getting one way audio even NAT is configured

Hi all,

I'm getting one way audio when calling over the SIP trunk i.e. end device B
(remote end of SIP trunk) can hear device A (softphone registered with
Asterisk) but device A can't hear device B. Even though I configured same
NAT configurations on other servers and they are working good. The NAT
configuration is listed below;

localnet=130.0.0.0/130.0.0.0
externhost=12.131.12.13
externrefresh=10
fromdomain=test.localhost.com
nat=yes
qualify=yes
canreinvite=no


NAT on device end i.e. my softphone (extension) has already set to yes with
canreinvite=no  but still unable to resolve this issue. SIP traces are
listed below;

Which device (A or B) is behind NAT with regards to your asterisk server?
Is that the actual localnet= statement you're using, because to my
understanding that is not the proper format to use (should be
localnet=x.x.x.x/y.y.y.y where x.x.x.x is your actual local network, and
y.y.y.y is your subnet for your local network).

[asterisk-users] Getting one way audio even NAT is configured

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.
