Linksys PAP2 locked to Vonage, support people funny

PAP2-NA firmware is available. Getting it to load onto the PAP2 is

the challenge. It's apparently not as simple as renaming it to the

file requested by tftp. That results in the tftp session shutting

down before the transfer completes.

Would be nice if someone, with the adequate hardware, could

interrogate the NVRAM of a PAP2-NA and

and extract the firmware image.

can see the web interface), but it keeps asking me a password to the

Admin Area and once connected to the net, it starts to download

vonage firmware. :(

OK since I've already wasted my Friday night, I might as well lay out

what I've found.

I've successfully changed the firmware to two other versions, a .10LSc

and a .13LSb.

It appears thought that the provider config is stored somewhere

outside of the main firmware, because despite flashing to different

versions, I am still prompted to enter a password for the admin

pages, and the device still makes requests to a vonage tftp server.

I tried a factory reset after loading each firmware, and it didn't

help.

I noticed that the device says it has a certificate installed. I'm

assuming this is what's used to authenticate/decrypt the .xml config

file the device is trying to load. If that's the case, then the

configs are likely signed with a key unique to vonage, and that

pretty much ends that direction. I think that will likely prevent

the loading of some generic, yet properly compiled config file, since

it won't be signed by vonage's key.

I read somewhere that older versions of the firmware had a particular

vulnerability that allowed config access - does anyone recall what

that was about?

Besides the PAP2 provided by vonage (and which we all here are trying to unlock) I also have a PAP2-NA, that was provided by my local VoIP provider, and which I've reset once with the RESET# command (no password asked). That, indeed reseted the unit, was able to make it into the admin pages. And it also has the Client Certificate:Installed thing. This unit doesnt download any particular configuration. It's just configured by hand using SIP proxy, user & password.

By the way, let's suppose I want to cancel my account with Vonage. My credit card is "broken" (doesn't allow any charges). Vonage tries to charge me $40 disconnection fee.. And it cant do it... What happens then? Does Vonage like sue you to obtain the money? or just nothing happens at all and you just keep a useless pap2 ?

thanks.

I'm sure they will send you to collections unless you talk them out of

the fee.

As far as the certificate goes, I now believe it's only in place to

enable HTTPS transfers of config info if the provider chooses that

mechanism.

I still haven't made any more progress on this thing..

Isn't there a way to trick the .htaccess file inside this thing to

allow access to the /admin directory? That's how the authentication

works, doesn't it?

Naw, that's not really possible...but I wouldn't be surpised if there were some "backdoor" somewhere in the http interface.

Still stumped....

Is it really worth the effort when you can get a Sipura?

Well.. let's say that I want to make it worthy for the money I paid

for the PAP2... :(

Figured out that my local VoIP provider doesn't configure the settings

by hand, but using a program that loads the config into the ATA.

For instance, when you go to the voice menu on the Linksys RT31P2 it

just says "Contact your service provider". No manual config

whatsoever...

I need to get my hands onto that proggie..

You think you're going to hack it! Not.

Anyone having any luck with this???

I really need to get this device unlocked, lol.

It's likely that they'll refer you to a collections agency: Vonage may or may not report the debt as unpaid to your credit report, then "sell" the debt to a collection agency, who then makes it their task to cajole, harrass and threaten you till you decide to pay up. If you have a strong will and don't mind a bad mark on your credit rating, then have at. :)

For me, it's not worth the hassle. If I ever cancel my Vonage service, they can have their useless PAP2 back.

According to

should download it's configuration..

Hi All, I just read this one on the net, I do not have one handy to try. Would someone willing to try and post the results. Thanks.

UPDATE Well it appers that Vonage let ~some~ info slip this morning around

I can get the PAP2 unlock unit. They sell for around $75.00. The ones

that are all ready locked by Vonage are not worth the trouble. I get

them directly from cisco.
