<br>
provider (internet) <--firewall--> Freeswitch (external IP) <--firewall--> Phone (internal IP)<br>
<br>
Freeswitch is outside the NAT, and looking at the packets, it is sending<br>
the correct IP addresses to the provider.<br>
<br>
All firewalls are whitelisted to send all UDP 1024-65535 through.<br>
<br>
As far as freeswitch is concerned there is no NAT. Unless I try to get<br>
the phone to talk directly to the provider. Which is something I am not<br>
even attempting to do right now.<br>
<br>
local-network-acl is set to localnet.auto<br>
<br>
If there was a codec negotiation issue, what would the symptoms be? I<br>
would expect dropped phone calls, not dropped audio. So I don't think<br>
that is what I am experiencing here.<br>
<br>
My gut feeling is that the remote provider is sending audio (wish I<br>
could prove it) which means traffic is getting blocked somewhere - most<br>
likely my firewall. So will concentrate my efforts here. Starting of by<br>
disabling SIP support in my firewall.<br>
