My PAP2 still loses registration after about 2 days.
What kind of modem? If not cable, configured as router? Router model/version? Post screenshots of System, SIP and Line 1 pages of PAP2 (with personal info masked, of course).

PAP2 Loses Registration after about Two Days
I am using an FTTP (Fiber to Premises) service, so my router is directly connected to the wall RJ-45 socket.
Router: Linksys WRT54GL - F/W: Tomato Ver. 1.25
ATA: Linksys PAP2
Like I said in my previuos post, there is some setting somewhere in the PAP2 that is preventing registration after an interval. Any feedback is greatly appreciated.

Re: PAP2 Loses Registration after about Two Days
Does your router get a public IP address on WAN side? If not, please explain.
Do you have static DHCP configured in your router for the PAP2? If not, are you sure that the PAP2's private IP address has not changed?
When you lose registration, has your public IP address or router's WAN IP address (if different) changed?
When you lose registration, does rebooting the PAP2 regain it? Rebooting both router and PAP2?
Did you lose registration while you had Reg Retry Long Intvl set to 30?

Re: PAP2 Loses Registration after about Two Days
- The router gets a public IP address (dynamic); however, it hardly changes.
- No, I have not set static IP for the PAP2. I just double checked the IP address and it's the same as before. No change.
- I had rebooted the PAP2 and router in previous incidents, but this time I decided to power cycle the PAP2 first, which didn't help; however, power cycling the router restored connection. This is strange since it only happens with voip.ms.
- I'll try with the Reg Retry Long Intvl = 30 again, to see if this prevents the issue.
I may switch to dd-wrt firmware to see if it makes any difference.

Re: PAP2 Loses Registration after about Two Days
I have used a PAP2T with Voip.MS.
Pretty much the only difference I can see between my settings and yours is that mine only works with "DNS SRV" set as YES.
Otherwise I agree, it's really starting to look like a router issue.

Re: PAP2 Loses Registration after about Two Days
I just noticed that you have Line 1 on the PAP2T-NA showing Use OB Proxy in Dialog set to Yes yet you do not show a name for the Outbound Proxy (in the left column). I have my PAP2's Voip.ms Use OB Proxy in Dialog set to No.
I'm not sure if this makes a difference with regard to your problem.

Re: PAP2 Loses Registration after about Two Days
This smells like a poisoned NAT association issue. To confirm that, the next time it fails, reboot the PAP2 only, verify that it still won't register, change the Line 1 SIP Port from 5060 to e.g. 5080 (but keep the same server). If it now registers, that's IMO reasonably convincing evidence.
For that issue, using proper port forwards (instead of DMZ) is likely to fix it with your present router. Of course, you should use either static IP on the PAP2 or static DHCP in the router, to ensure that the forwarding goes reliably to the right place.

Thanks for the advice Stewart. I'll change the SIP port to 5080 next time it fails. Hopefully, I can find the culprit.

Apologies ... but my skills (as a gastroenterologist) only extend to experimenting with various settings on PAP2Ts ... with a wide variety of VoIP providers. For CallCentric I set Use DNS SRV to Yes and Use OB Proxy in Dialog to Yes. For all the others --- VOIPo, ViaTalk, StanaPhone, FreeDigits, Voip.ms, Gizmo5 (now GEO), SipGate, Voxox, VoiceStick, AxVoice --- these are set to No.
For providers calling for OutBound Proxy (& Dialog) use --- VoiceStick, FreeWorldDialup, CallCentric, FreeDigits --- I entered a name for the Outbound Proxy ... such as outbound.freedigits.net.
Perhaps one of our technical members will jump in with a definition of the three Outbound Proxy settings.

Stewart, I just put the router in the DMZ zone. Hopefully, this will eliminate the issue.
N9MD, I'll set "Use OB Proxy in Dialog" to No to see if that makes any difference.
Anyone else has any opinions about "Use OB Proxy in Dialog" and "Use DNS SRV" settings?

The OB Proxy is something totally irrelevant for most situations. Unless you're going through a SIP proxy before getting to your ITSP, you don't need this.
DNS SRV is a way to make VoIP more user friendly. For example, SRV records allow someone to call typhoon@hisplace.ca instead of having to call 17005551234@sip.typhoonsprovider.net. In the context you're probably more curious about it basically allows your ITSP provide a single domain where your device can utilize automatic fail over to a secondary or third gateway if the primary becomes unreachable for any reason.

Re: PAP2 Loses Registration after about Two Days
I am experiencing problem all day today without changing any configuration......ATA device seems to fail registration after each call then re-acquire only to fail registration again after the next call....don't know what could be the problem......I haven't changed anything .......aggh.....
UPDATE @ 18:19 Problem fixed by using the IP address instead of the hostname, I guess I just discovered the Cisco/Linksys SPA-2102 DNS bug today. Curious, I am using the latest firmware 5.2.10 - is this a new bug ?

Typhoon, I've been successfully using a PAP2T with voip.ms. I'm assuming (but could be proven wrong...) that the PAP2T setup would be nearly identical to the PAP2 that you have.
I've documented step-by-step instructions for voip.ms using a PAP2T: »www.frugalnerd.com/doc/voip-pap2t-setup
If you're game you could reset your PAP2 to factory defaults and try following these steps.
FYI I'm using dd-wrt but others have followed these steps using other routers and I haven't heard any reports of lost registrations to voip.ms.

It also appears (albeit in a different form) in my PAP2T and my SPA-921 IP phone. You'd think Sipura/Linksys/Cisco would have noticed by now.

Thanks Scott. You gotta nice step-by-step guide there. There are a few differences between your recommended settings and mine. I will apply your settings next time it fails. Right now I've put my PAP2 in DMZ zone to see if I can isolate the issue.
Mango, if you don't mind me asking, what is your ping time to us3 server. Mine is reduced to ~33ms!

Stewart @ 31st Oct 05:13PM:
Re: [Other] Questions/Issues Regarding Voip.ms VOIP Service
If you suspect a DNS problem, try changing your Primary DNS to e.g. 4.2.2.1 .
IMO it's very unlikely that DMZ will help, unless it happens to cover up a bug in your router firmware. DMZ means: If an incoming packet would otherwise be discarded, send it to the DMZ host, with the destination port unchanged.
Now, unless your problem is caused by DNS or another low-level networking issue, it's likely that failure to register is one of:
1. Outbound REGISTER request not being properly sent.
2. Server rejects request, ignores it, or sends reply to wrong place.
3. Incoming reply not being properly received.
DMZ clearly won't help (1) or (2). It could help (3) but it's hard to think of a situation, given that (1) and (2) are ok, where that would arise, except for a router bug.

Well, as a matter of fact...
My ping time to US3 is 
120ms! That's right, 120ms! And do you know why? Because I switched from Shaw to Telus and Telus routes traffic to US3 via Washington, DC!
I raised it with their support but their TSR didn't even know what latency was. I posted in the Telus forum and was given some suggestions but those haven't panned out so far.
I'm using CA1 at the moment. 80ms isn't so bad I guess :(

Stewart, my PAP2 failed again today; so this time, without changing the server, I rebooted the PAP2, verified that it didn't register, and changed the SIP port from 5060 to 5080. The change made the PAP2 work again. I switched back to 5060 without any issues. The part that I don't understand is I had already put the PAP2 in the DMZ with static internal IP, so I don't know what exactly is causing the issue. :mad:

Re: PAP2 Loses Registration after about Two Days
I'm experiencing the same issue here. Its quite weird. My PAP2T will stay registered for a few days and then it needs to be rebooted. A couple times that did not even work so I changed from US4 to US3 and so far it always come back after a reboot. I have Voicepulse on the other line and it never has this kind of issue.
I will try the HOWTO by FrugalNerd the next time it fails to register. I'm using U-Verse and have tried putting the PAP2T in the DMZ as well.

Stewart @ 11th Nov 01:04AM:
Re: PAP2 Loses Registration after about Two Days
If a reboot fixes it, there was most likely a transient network error. Set Reg Retry Long Intvl to 30; with luck it will regain registration quickly.

crazyk4952 @ 11th Nov 08:33AM:
Re: PAP2 Loses Registration after about Two Days
I believe I have experienced the same issue as well. I have VOIP.ms configured for line 2 on my PAP2T. Last night, voip.ms was not showing it as registered. However, I still got a dial tone, was able to place outgoing calls, and the green "line 2" light was on. I was not able to get incoming calls.
I set the PAP to register to the main account (instead of a sub account) and this fixed the problem, although probably temporarily.
I just set the Reg Retry Long Intvl to 30. I will see if this helps.

scooby, has your PAP2T been keeping its registration?
I live pretty close to you in the Chicago northwest suburbs and my current recommendation is to use US2 (sip.us2.voip.ms).
US3 is pretty far from us in Los Angeles. And I had some problems a few weeks ago with US1 and US4 - voice quality issues, not registration issues but these may have gone away since I experienced them.

crazyk4952 @ 14th Nov 07:09PM:
Re: PAP2 Loses Registration after about Two Days
I have Set the Reg Retry Long Intvl to 30 and this seems to have resolved the problem. Over the last several days, I have been logging into my voip.ms account and have verified my device was registered every time. I also have not missed any incoming calls.
Before I changed this setting, I guess my device would fail an attempt to register and then wait 20 minutes before trying again?
As long as it is fixed, that's all I care about!

Typhoon @ 20th Nov 09:01PM:
Re: PAP2 Loses Registration after about Two Days
Resetting my PAP2 to factory settings, seems to have helped a bit, but not fixed the issue completely. One thing I suspect is that after the reset, the reg. exp. interval was reverted back to 3600. This time it took 10 days until my pap2 failed as opposed to every 2 days. I have changed my LAN's internal IP address to a standard Private IP address to see if that can solve the problem.

I've had voice quality issues with US4 (NY) even though it's close to me!
For me US1 (Houston) worked better for voice quality, even being so far away!

Question about Calling Ques/Ring Groups
...maybe someone here can help me understand "ring groups" better:
So what I want to do is I would like my voip.ms DID ring five times and then:
If no answer --> call gets forwarded to my cell after the 5th ring.
If no answer again after 5 rings--> call gets forwarded to my voip.ms voice mail.
Can I implement the above using ring groups?
reply
Mango @ 22nd Nov 01:35AM:
Re: Question about Calling Ques/Ring Groups
What you're describing is sequential ringing. VoIP.ms has simultaneous ringing. What would happen is your cell and your VoIP.ms DID would ring at the same time, and you can decide which device you would like to answer your call with.
The advantage is that the caller does not need to wait a potential ten rings to get your voicemail.
