Strange Gargoyle router firmware problem

I picked up a Netgear WNDR3700 for $0 at some point last year, and until recently it did a great job of gathering dust. But last week I put it to work running Gargoyle v1.5.9.

However, I've hit a strange issue, phone trees no longer work, or at least the one at my kids doctor's office doesn't. I failed to find any info on the Gargoyle forums, and googling anything with the term "phone tree" included returns a whole host of un-related stuff.

Any suggestions on what the issue might be? Or should I just return this router to dust gather.
Thanks!

@mlord as I recall you are using voip.ms also, what setting are you using on you ATA and at voip.ms for DTMF tones?

I'm sorry, I don't have an answer for you, but I wanted to ask: what made you choose that firmware over the others? I've never heard of Gargoyle before, but I haven't been looking much.

Thanks!

Fair question Dignan, and neither had I.
I've use DD-WRT in the past, but it is now near impossible to find a straight answer on their website, the router database conflicts with the wiki, which conflicts with the threads. Most recently I've been using vanialla version of Tomato and TomatoUSB, but they don't support the Atheros chipset. So I went hunting. I tried to use OpenWrt but the lack of a GUI and drivers in the base install made for too steep of a learning curve. Hence I ended up at Gargoyle, which is based on OpenWrt.

Gargoyle does have some interesting features to it, though I didn't miss not having them when I was using TomatoUSB. I'm also finding an issue when I enable N wireless on the WNDR3700v1 - speedtest.net tests return about a fifth of the performance, and occasionally fail the upload test. Not that I need N...

If I can't resolve the DTMF tones issue, which is likely just a setting on the ATA or at my provider that needs to be tweaked, I'll flash the router back to OEM and Freecycle it. If someone here wants it, it is their for the cost of shipping.

I use a PAP2T-NA as the ATA. It has "DTMF Tx Method" set to "Auto". The voip.ms account also has "DTMF Mode" set to Auto.

DTMF seems to work fine for the few answering-system-hell companies that I still "press xxx to xxxxx" with.

Some links I found that appear relevant.

And then I found this link, in particular the "Random Beeps or Tones" paragraph -- I have that issue from time to time.

Mmm.. based on that wiki entry, I've now changed the DTMF setting to "Inband" in both places. I guess I'll see over time if that causes anything to stop working.

At least the voip.ms voicemail menus still work.

Oh, with TomatoUSB on my Netgear 3500L, there is a checkbox on the Advanced -> Conntrack/Netfilter screen, for a Tracking/NAT helper labelled "SIP". I have that *UNCHECKED*, and my ATA seems happier with it that way. This seems to have pretty much eliminated re-registration issues.

Cheers

Thanks Mark, I'll give those links and suggestions a read and try tonight.

We did have that "Your phone is making tones." problem in the past, and maybe it was then that I set DTMF Tx Method to InBand on both the ATA and voip.ms site, so no change there. Using there DTMF test number, things work fine. I'll ask my wife to try the kids' Dr office tomorrow.

Anyone want a *perfectly good* WNDR3700v1?

No :SIP: checkbox to uncheck on Gargolye?

Not that I could find.
