VoIP with t-home internet

Hola,

I just stated with T Mobile Home Internet and needed to work out a few bugs.  (Security IP Cameras, VOIP, VPN).  I too use Magic Jack.   All these issues cleared up once I connected an external wireless Router (Asus RT-AC1200).   My Magic Jack works great now.

Hope this helps,

Bob

I have exactly the same issue as robertcohrs

Has any got thier magicjack to work with tmobile home internet?

Just spoke with a girl called Crystal from the customer service . Waiting time was zero minutes. She told me that they are aware of the "problem" that many VOIP devices can't function by default. She also assured me that it's a matter of sending request to register a particular device with them (in my case it's a Grandstream GS-GXP2140 VOIP desk phone). Which she did sent.

She collected my download and upload speed (asked me to test it in real time).

I am still kind of skeptical based on reviews here that say that all these reps do is lying to you. However, she told me to wait 24-72 hours and gave me "complaintID" I could use to  track the status of the request.

I’ll keep you guys posted.

Ok, here is my report: nothing happened. Nobody contacted me, the problem wasn't fixed. At all.

If T-Mobile is still blocking the necessary ports on its grey Gateway router, how does a MagicJack work when plugged into it?  My VoiP phone requires ports 5060-5070 for communication with the server and UDP 10000-20000 ports to be open for two way voice communication.  I have yet to find a workaround.

I have the same problem with MagicJack. Mostly on outbound calls. The other party cannot hear me but I can hear them. It works sometimes. Less than 50% of the time. Sometime it will work for a second or two then the other party stop hearing me. If it is firewall settings, port blocking, SIP ALG, wouldn't it fail 100% of the time? 

I'm glad to see that I'm not alone here. My wife blames ME for trying to save us over $2K a year by moving from COMCAST to T-MOBILE business internet.

That’s right BUSINESS INTERNET.

I *NEED* to use a cordless phone system, connected to the internet to take orders for food, but my MagicJack system (which, BTW, I have used at home previously and have NEVER had a problem with, has an issue with our T-MOBILE 5G Router (the black tower one).  We have NO access to the SIP ALG on this Router.  I did everything I could to make this work; 

• changed power supply for the MJ device.
• connected the MJ device DIRECTLY to the router (there are 2 Ethernet jacks; one goes to my 8:1 switch, the other connects to a VOICE device. Everything ELSE works GREAT!

So my question is:

Has ANYONE had any success using a separate router, directly connected to the TMOBILE router, to use Magic Jack?

I would purchase a land line, but NOBODY offers a land line anymore. They are ALL VOIP/Internet solutions.  That means that I don't expect much greater success using other VOIP services (e.g. Ooma).

It is ODD that T-Mobile wouldn't FIX this issue, but maybe it's just me. I'm an MSEE and presume that access to those settings is NOT a big issue, and if it fixes the problem, they would likely make lots of friends. HELL, if I was a consultant to T-Mobile, I'd TELL THEM TO OFFER A VOIP SERVICE for $10/month and I'd bet they'd make BANK!

ANY suggestions/experience would be appreciated.  I do not want to go back to COMCAST. I am happy to make a one time hardware purchase for long-term service cost savings, but I *NEED* to have a working phone SOON, or I will be pressured to pay COMCAST their blood money...

Just got done talking (live Chat) to Magic Jack.   All looked good with the exception on the "Ping"   Magic Jack wants   25ms or less and I'm getting about 31 at the time of the Test.   Magic Jack says that a higher ping can cause some Audio Issues.  Of Course, Magic Jack says to contact "My Internet Provider" about the higher Pings,  and if I did that, I'm sure T Mobile Home Internet Techs would say contact Magic Jack about rising there Ping Tolerances.   

Currently I would say my Magic Jack is working,  Dial Tone is clear,  I'm able to send and receive calls.   So if from time to time (which I had with spectrum too) I have an issue  it is well worth it to have magic Jack for the saving and just deal with an occasional hick up.   We here still have 2 cell phones for back up calling.

Their Comments;  (Magic Jack)

"Since you are going to reach your internet service provider. I will be also suggesting you to ask for them for assistance in opening internal ports 5060-5070 on your router (UDP). These are the ports that allow the magicJack to communicate on your router/modem.

Also, please check with your internet service provider/router manufacturer to check if it's possible to disable the settings called "SIP ALG" on your router/modem. This setting could be interfering with the magicJack service (though it is intended to be helpful) and can cause audio issues specifically​ one-way audio (the other caller can't hear you but you can hear them and vice versa).

Based on the result of your internet connection, it seems that one of the minimum requirements of magicJack does not meet by your internet connection  (less than  25ms ping/latency), which can cause audio issues and a technical problem with magicJack service. You will need to consult with your internet service provider, they may lower latency/ ping with your internet connection."

If you have a regular wifi router, connect it to the ethernet port on your T-Mobile gateway and then connect your device to the router and see if it works that way.

Thanks da.down. I tried it with a network switch and two wifi routers, still the same issue. It works fine when we call out. But on incoming calls we can hear the caller just fine, but they can hear us for only about 2 seconds.

When trying the routers I just connected it like a switch. LAN to LAN. And did not create a new network.
