Note also that if you point to the DNS name rather than the IP address of the
asterisk server on the phones trying to register, you can set NAT=NO on the
asterisk side and the sip FIXUP command on the PIX will handle everything
correctly making this workaround unnecessary

Subject: [asterisk-users] oneway audio with asterisk behind cisco pix 506
Hi,
I have the Cisco PIX 506 firewall right in front of the asterisk and I am
getting a one-way audio. I need your help/guidance to resolve this problem. I
have the “fixups” disabled for SIP in the Cisco PIX 506. Any help rendered by
you in this subject is greatly appreciated. I have been breaking my head trying
to resolve this problem for more than one month. I have included the sip.conf
and the extensions.conf below.
[SIP.conf]
