Andrew, I did check this on the HT286, it was unset. I set it to the FS server IP, but I got the same results. -BDF On Tue, Mar 20, 2012 at 1:35 PM, Andrew Cassidy < andrew@cassidywebservices.co.uk> wrote:
My thought at this stage is that the ATA is trying to send the ACK directly and not to FreeSWITCH using the Contact header. If I recall correctly, GS's can be configured with both a registrar and an outbound proxy. Try setting the outbound proxy to the FreeSWITCH box, see what happens.

This is why I love Wireshark so much! Look at this purdee graph it makes:
See all those 200 OK's that your FS is sending to the Grandstream? Guess what your GS is sending in response to those: NADA! If you look at the BYE that FS sends to the GS you'll even see the reason:
SIP;cause=408;text=\"ACK Timeout\"
FS never gets an ACK back from the GS. So the question is: why? I'm unfamiliar with the GS so I'll have to defer to those with more experience than I. However, I think you'll find that tcpdumps and analyzing w/ Wireshark is extremely helpful. (Open the pcap, click "Telephony > VoIP calls" and then a new dialog opens. In this case it shows two calls - meaning two call legs. Click "Select All" then click "Flow" and you'll get the cool graph. Click around and see what other stuff does. :)
I'm thinking of doing a FreeSWITCH conference call presentation on the subject of collecting pcaps and doing Wireshark analysis. Let me know if you guys think that's a good presentation.

Michael,
I did replace the IP's for security purposes, but now I've realized that it's needed and it's not really that big of a deal. I'll end up changing the Flowroute creds after this is fixed up. The prior siptrace is exactly one call (two legs). I don't think it's a carrier issue, as I've tried calling a buddy's server direct sip with the same issues.

We have scores of machines behind NAT talking to Flowroute with no problems, so there's got to be something potentially non-obvious but easy that needs to be set/unset. I noticed in the SIP trace that there are several calls. It's hard to know what's what. I think your best bet is a pcap analyzed with Wireshark, as was mentioned elsewhere in this thread. I also noticed that you redacted IP addrs - you won't be able to do this with a pcap. If security is an issue then I'd say get the pcap and let us know here on the list, then those who can have a look will email you privately and you can send the pcap file to them.

Alright, so I admit... I'm a little rusty when it comes to NAT, etc. I've only set up FS so far on machines with no NAT, so this is sort of a new experience for me.
I have a FreeSWITCH server located on the same local network as all of my phones here at the house. When I try to make a call to Flowroute, after about 30 seconds the call drops. It also does the exact same thing when I call a buddy's server directly via SIP.
Here's a siptrace of the call (I didn't think that the actual FS log would be much help): http://pastebin.freeswitch.org/18697
...and here's a paste of 'sofia status': http://pastebin.freeswitch.org/18698
