TOT Fiber Optic modem and SIP phones

[Negita43]

Hi I wonder if anyone can give me a few pointers about this.

 

I have a TOT fiber optic internet access with a modem supplied by them.

 

I recently bought an OBIHIA 202 SIP box and have been trying unsuccessfully to get it to link to one of the LAN ports on the modem.

 

The modem is under a desk and not easily accessible but tonight I removed it and then discovered there are two telephone sockets on the unit. Then when I inspected the box I saw the model was

AN 5506-04-B SIP.

 

Now I am wondering if this is actually a SIP enabled modem and I don’t need the OBIHAI unit.

 

Subsequently I went into management on the modem and found an option labeled VOIP (see image) and I am wondering how to set up this option,

 

Anyone have any experience of this, how to enable the VOIP fields and what data to enter or altenatively how to get the OBI202 working.

 

Thanks

you have to connect  OBIHIA 202 SIP box to LAN port only as any pc/laptop and I think your problem about the setting that you should do in OBIHIA 202 SIP box so if you can connect to the internet Laptop to the interent through lan so the box should work and the problem is the setting in the Obihia ...the tot modem is voip enabled but for their Thai sip number that you have to contact TOT and request this service with new THAI phone no. through VOIP

Thanks the OBI box is connected properly via its lan port to the modem but every time I try to add the box via the OBI talk website I get a no service configured error message. Thanks for the info on the TOT SIP I do not want/need a Thai number.

 

Probably the modem settings are not compatible with the OBI box and I am talking (via email) with OBI but it is very slow going. Its impossible to find out anything about the Fiberhome unit as their website appears to have no support options.

You may find that the modem/router has a SIP ALG option. If it does you may need to turn it off. My PC SIP software does not work properly if the SIP ALG option on my router is on. Works fine with it off though.

 

You may also need to assign a fixed local IP address to the OBI box and put this in the DMZ on the modem. Or use a STUN server. It all rather depends on the individual equipment though and without studying the manuals of both units it's hard to tell.

 

As for the SIP function on the TOT modem, this may be locked into some service that they provide but I suspect that it isnt. If it isnt then basically all you should need to enter on the modem would be the SIP server address, your SIP login and SIP password. It should work with any SIP provider anywhere in the world, always assuming that TOT haven't locked the modem to their own servers using modified firmware. Again you would need to study the manual to know where to enter those details. At a guess it may be in the "management" section.

Thanks Kitten Kong

 

Thanks for your input

 

I have looked for the ALG option in the modem but cannot find it.

 

With regard to The DMZ my modem has 3 options Off, Auto and Manual. I have tried all 3 but still have the same issue.

 

Can you tell me what is a STUN server?

 

What I can't understand is that I have a Skype telephone connected to a switch on my system and it has been working perfectly for several years (I know Skype uses a different VOIP protocol but it just seems odd that one will work and the other will not).

 

With regard to the VOIP section in the modem's management there are two rj11 sockets and two entries in the VOIP section (see my original post) BUT there appears to be no way to enter data into them so I can only assume that this is locked by TOT.

 

As far as a manual for modem settings goes I can't find one even on Fiberhome's site only a basic guide about the modem not its management.

 

As far as OBI support goes at the moment they are pretty useless (they have asked for the modem model 3 times and been given it 3 times!!)  I am hoping that front line support will escalate it soon.

 

Thanks again for your interest.

A STUN server is sometimes necessary to help you to receive incoming calls if you are behind a NAT device and cant forward the necessary ports. Your SIP provider would normally have their own STUN server. These days in most cases it isnt needed, and the lack of one would not prevent you from logging in to the SIP server anyway, so even without it you could still test that the OBI box is working correctly.

Some modem/routers have two login codes: one that shows general status information and simple settings like wifi etc, and another that allows the user to see more complex settings. If so the technicians often only leave the simple access code and keep the other secret. It may be that your modem is like this.

 

And it certainly could be that the modem is designed to get its SIP programming remotely from the server if this option is part of your package. This is very common with proprietary modems in Europe when multiple services (SIP, IPTV etc) are offered by the ISP.

Sorry for the delay in thanking you for the reply KittenKong.

I think the best that you can do is to set TOT modem in bridged mode and attach another wifi router such as Asus then this should fix your problem as TOT modem will not interfere with the connection any more..

I don't know anything about SIP phones but do have a MagicJack that plugs directly into one of the free LAN ports on my TOT ZTE Fiber modem

 

I don't understand why the OP has the modem "under " the desk.  There is a box that TOT attached to the wall where the line comes into the house but then run a small cable to the modem that sits on the top of my desk.  So I have easy access to the LAN ports, but more importantly the ability to change the orientation of the Wifi antennas

 

I too was excited to find the "phone" jacks on the modem, hoping that they were just like the ADSL splitter on the old ADSL connection, but unfortunately when you opt for TOT fiber you lose the ability to use your regular phone line, unless you pay to keep the phone line  in addition to your fiber connection

My router is in a cupboard as I never need to touch it. I certainly would not want it and all its wires cluttering up the top of my desk. Occasionally I restart it remotely via the web interface but apart from that it requires nothing so there is no point in having it conveniently located.

 

I dont see why you would need to alter the orientation of the wifi antennas anyway?

^^^^ If the signal from your wifi is poor then you probably need more access points or Powerlan extenders, or simply a better router. Certainly more effective than fiddling about with the orientation of antennas. I adjusted my antennas just once and have never touched them since which is why my router can sit happily in a cupboard.
