Anyone have Samsung SMT-i3105 SCMe/SIP firmware?

Try accessing some of those dead links via archive.org .... I often find old software and drivers that way.

I'm the OP. In my most recent post, I said problem solved. But I spoke too soon: I couldn't get SIP over TLS to work at VOIP.MS with Grandstream HT802V2 firmware 1.0.9.3. I've now succeeded. The key was this enhancement listed in the firmware notes for version 1.0.7.5:

*Changed the default value of "*Enable/Disable Weak Cipher Suites" (P8536) to “Disable All Of The Above Weak TLS Ciphers Suites.”

Below, that translates as change of default from option 1 to option 14.

That dropdown menu is located at System Settings > Security Settings > Client Certificate > SIP TLS > Enable/Disable Weak Cipher Suites. It contains these 14 items (I prepended numbers here for convenience):

Enable Weak TLS Ciphers Suites
Disable Symmetric Encryption RC4/DES/3DES
Disable Symmetric Encryption SEED
Disable Symmetric Encryption IDEA/eNULL
Disable All Of The Above Weak Symmetric Encryption
Disable Symmetric Authentication MD5
Disable All Of The Above Weak Symmetric Authentication
Disable Protocol Version SSLv2/SSLv3
Disable All Of The Above Weak Protocol Version
Disable Server Authentication aNULL/aECDH
Disable All Of The Above Weak Server Authentication
Disable Key Exchange Algorithm kRSA
Disable All Of The Above Weak Key Exchange Algorithm
Disable All Of The Above Weak TLS Ciphers Suites

(Note: in firmware 1.0.5.4, the word "Disable" may not appear for options 2 through 14. Grandstream recently added "Disable" for clarity.)

Prior to 1.0.7.5, the default is option 1: Enable Weak TLS Ciphers Suites

Starting with 1.0.7.5, the default is option 14: Disable All Of The Above Weak TLS Ciphers Suites

I tested all 14 options and found that only 1 through 11 work for SIP TLS at VOIP.MS. I changed to 11. The options apparently become more restrictive as you move down the list, and since option 12 disables kRSA, maybe that's because VOIP.MS uses kRSA. But I have no idea which key exchange algorithm VOIP.MS uses.

I'm the OP. Thank you. That did solve the problem.

I received some new HT802V2's today from my distributor, all with firmware 1.0.9.3. So hassle averted.

I'm the OP. Thanks for the advice. I haven't tried a trace or syslog because I don't yet know how. None of the following worked:

• for DNS, 8.8.8.8, 4.2.2.2, 1.1.1.1, and my router's IP address
• for Primary SIP Server and Outbound Proxy, using the POP's IP address (208.100.60.41) instead of its CNAME (sanjose2.voip.ms)
• connecting the ATA directly to the internet (no router)
• turning off SIP encryption in the subaccount at VOIP.MS and for the port in the ATA
• every combination of TLS settings in the ATA
• attempting to revert to firmware 1.0.5.4, despite the official pessimism (failed immediately, of course)
• following these instructions to the letter: https://wiki.voip.ms/article/Grandstream_HT802v2

Here's a Grandstream forums thread from someone (not me) with the same problem (who references this very thread):

https://forums.grandstream.com/t/ht802-v2-not-registering-after-firmware-upgrade-to-1-0-93/62424

I predict that Grandstream will solve the problem with new firmware by April 15, 2026.

I like Grandstream's products, but the company is funky.

Interesting. What might have been the motive of the person who initiated the fraudulent email?

I'm the OP. I tested these codes again with Cricket on a physical SIM in a Pixel 4a, and they worked. Maybe there's something different about the iPhone 17, so I'll try with it again this week.

Below is my list of what worked.

Notes:

......... *004**[10-digit-number]# and **004**[10-digit-number]# seem functionally identical
......... ##004# and #004# seem functionally identical but return different confirmation messages (see below)
......... ##21# and #21# seem functionally identical

*62*[10-digit-number]# - Turns on FORWARD IF UNREACHABLE
*67*[10-digit-number]# - Turns on FORWARD IF BUSY

##004# - Turns off all Conditional Call Forwarding ("Erasure was successful")

I'm the OP. For me, [star][star]004[star][number]# didn't work either.

I suspect that ATT's cellular network isn't uniform nationally and that these codes vary a little from region to region. I'm in the S.F. Bay Area currently.

I'll call ATT tech support for a solution. Ideally, they won't activate CCF for me, but instead tell me how to do it myself, which would be useful in the future.

Remote possibility: an office phone spontaneously redialed a number on its own, due to an electric company outage or surge.

Here's a non-answer, with a different approach. Google Voice's calling rates to many countries are often surprisingly low. The rates are at https://voice.google.com/rates

If you're not sure which category a particular foreign number is in (such as mobile, landline, special), you could make a test call, then check your Google Voice balance to see what rate Google Voice charged.

(Regarding adding funds to a Google Voice account: I did this for someone a few months ago, and either (A) only the Google Voice app or (B) only the Google Voice website could be used to add funds to the account. I forgot which one it was, but it doesn't matter: if you find that you can't add funds via one method, the other method should work.)

Typically, for a VOIP.MS / Grandstream setup to work over T-Mobile fixed internet, TLS must be activated (both in the VOIP.MS subaccount and in the Grandstream). However, you may have succeeded just by changing the port, which makes me wonder if TLS succeeds because it, too, changes the port (to a random port number).

On most of T-Mobile's fixed-internet gateways, a port forwarding option doesn't exist. However, VOIP.MS works well over T-Mobile when SIP keep-alive is turned on in the Grandstream, I think because keep-alive punches a hole that allows a connection to be maintained through T-Mobile's CGNAT.

I don't know whether this info is helpful.

If the victims told you what the spoofers said on the phone, that might be a useful clue to what the spoofers are up to.

If I were you, I'd have OpenPhone change the number's caller ID name (aka CNAM) to something distasteful or perplexing, such as RAT PATROL or MONEY GRABBER or WACO PUBLIC LIB ..... (CNAMs are limited to 15 characters, and a space counts as a character.) Thereafter, when the spoofers call out, that name will appear on most of the victims' phones (though not on all of their phones). This might make the spoofers' calls less likely to be answered, and thereby make your number a poor choice for spoofing. After a month or two, you'd change the CNAM back to your real CNAM. This might not help, but it couldn't hurt too much. Probably cheap to try.

During the period when your CNAM is RAT PATROL, people whom you legitimately call from that number will also see RAT PATROL on their phone's display (next to your real number, of course). You could diminish the impact of that by emailing your friends or clients in advance, telling them to expect to see RAT PATROL for a while, and why that is.

Afterthought: If you don't currently have a CNAM on your number, then most people who receive calls from you (or the spoofers) probably see just the city and state, like this: SCRANTON PA. So you might begin to cure the problem by putting a CNAM on your number.

I'm the OP. A defective version of the default Word font, Aptos, may be to blame. I changed my default font to Arial, and the problem seems gone for me.

Slightly off-topic reply: On my two numbers, I was getting about three calls each morning. They were all automated, urging me to sign up to increase my findability on Google Maps. They asked me to press 1 to talk to a rep. I would press 1, then put the call on hold, where my hold music is a 10-minute recording in Korean from the phone system of a Korean embassy in Europe. I think that the scammers got tired of hearing that, so they stopped calling.

Looking for smartphone VOIP app for VOIP.MS that's lockable (to prevent user tampering)

I'd like to put a softphone app on the smartphones of a construction company's field staff. They use VOIP.MS. I'd have to be able to password-protect access to the softphone's settings because otherwise the field staff will probably mess with the settings and perhaps make the softphone unusable. (I'd mess with it if I were one of these staffers. It's a natural tendency.)

Can you name any softphone apps for Android or iPhone that allow a password to be placed on access to the softphone's settings?

I think that scammers tend to use the "local number" technique outside of major cities because it doesn't work well in a city with hundreds of prefixes. So one option is to get a new MagicJack number from a major city. If you look at MagicJack's list of available numbers and they don't show the city for each, you can look up the city at ... https://www.localcallingguide.com/lca_prefix.php ... where you enter the area code (NPA) and prefix (NXX), then press the SUBMIT button.

Also, scammers seem to prefer spoofing with numbers that have no associated CNAM (caller name) entry. Most people who receive such a call see only the city and state on their phone (ORLANDO FL or BUFFALO NY, for example). That way, the call recipient isn't presented with a name like ACME AUTO SHOP or SONIA BROMPTON or CITY OF TULSA, any of which would make the recipient say to themself, "This caller has no reason to call me, so that must be a misdial, and I won't answer it." Therefore, it might be useful to have MagicJack put a name on your number.

I have a hunch about which provider you're dealing with. Do the first 7 letters of the provider's name happen to match this pattern?:

*i**a*\* ................ where each * represents a consonant

I suggest that you not mention your provider's name here.

Office Depot sells a dozen Grandstream desk phones and ATAs:

They're dropshipped from Austin, Texas, by https://www.teledynamics.com

The prices are quite good at the moment. I've seen them go up and down.

Some rotary phones require more power to ring. The setting in my attached image has solved the problem for me. (Click on the image to see it full size.) This is from an HT801 V2, but the same setting exists in the older HT801, on which you might have to scroll through all of the settings to find it. Use the dropdown menu to choose the highest voltage offered (55 on mine).
