Voip Problems In Phuket

[simon43]

I'm having some problems installing a 'DeecallPlus' VOIP service at my hotel in Phuket. I signed up for this service and got the free VOIP interface box. At my BKK condo, I plugged this box into my ADSL router, plugged in my analogue phone and voila!, I had a VOIP phone service.

So I then unplugged the unit and brought it to my hotel in Phuket, plugged it into the router, plugged in my analogue phone and it doesn't work! I sometimes get a dial-tone and sometimes a busy tone, but I never get connected to the destination phone number.

I did some checks and discovered that the url of the Deecall server was 'missing' from the ToT DNS server, (I wonder why??). After changing DNS addresses in my router to a 'public' DNS server, my VOIP box can now connect to the Deecall server, (because the status indication on my account webpage changes from 'offline' to 'online' when I power up my VOIP box).

But I still get no end-to-end service. I checked my router and it all looks fine. I added a NAT for port 5060 (which I think is used by VOIP, but still no joy).

It's my guess that ToT is blocking the ports that are usually used by VOIP services, but I'm not really sure. Does anyone in Phuket have experience of using VOIP with ToT lines? Can someone with more knowledge than me about VOIP suggest what actions I could take to either test/confirm the problems or to resolve these problems?

Any help much appreciated!

Simon

Update - Using one of the online test services, it indicates that SIP port 5060 is being blocked! But port 6000 is not blocked. Can anyone in Phuket confirm that ToT blocks port 5060? If so, I suppose the only solution is for my VOIP provider to change port at their end....

If the hotel is using a digital PABX system you'll have some probs. Check out that to first.

You may need to connect the analog phone line directly to the VoIP unit by bypassing the PABX!

Which ISP are you using? And which VOIP interface box?

[simon43]

No PBX.

ISP is TOT 1 MB

VOIP box is Dlink DVG-2001S

This isnt really answering your question but..

I have TOT goldcyber and nothing I can do will allow me to have 'open ports' for P2P and torrents.. I have my routers and modems all set up so they should work but they never do. So I am fairly sure that TOT does some form of port blocking.

[simon43]

LivinLos, that's the answer that I suspected.....

I'll need to look at alternatives to using ToT...

Simon

[onethailand]

ToT is bad - their broadband is also one of the slowest in Thailand. Not sure about port blocking because I use True and CSLoxinfo for ADSL (office and home) and I am pretty sure they don't block port 5060.

Maybe you can take it to a friend's place or something and check if another ISP will solve the problem?

[simon43]

Unfortunately, I can only use ToT at my location .....

But what about the CAT aircard that I've read about? Does that support VOIP?

I suggest you talk to some of the other ISPs, surely ToT can't be the only option... you may have a ToT phone line but that doesn't prevent other ISPs from providing service...

No idea what the CAT Aircard is, but I wouldn't pin my hopes on anything CAT provides either.

[LivinLOS]

Thats true.. You can use the TOT line and CI lox or Jasmin as the ISP..

You still have to pay the 1000 baht to TOT tho as thier argument is you pay for the line and the ISP is a 'free service' added..

Are you shure you only need port 5060 ? Do you remember the settings from your router in BKK ? Do you have a complete description about the required settings from your VoIP-Provider ? Is it possible to get a connection without the VoIP-Box for example with the software from the VoIP-Provider, because then it would be possible to test the connection without this box but with your computer.

It´s necessary to isolate the reason of this effect - may be I could help you.....may be.

In my condo I use VoIP from Betamax (voipdiscount) with maxnet and my LapTop. Sometimes I have problems because ADSL is to slow, but if not, it works perfect.

The Deecall service uses a POTS (analogue) phone which is connected via the VOIP interface box to the router LAN. There is no software to install since the service doesn't use your computer.

I'm pretty sure that it is ToT who is blocking port 5060. My router is completely 'open', with no firewall configuration right now. Using my computer, I can connect to remote servers on other ports, but I cannot connect to remote servers who have port 5060 available for test connections. Draw your own conclusions from that....

Yes, I could try switching to another ISP. I actually found the ToT service and support quite good. But if they are blocking ports (for wahtever reason), then I need to change my ISP.

The Deecall techies are looking into this problem, so I'll let them confirm 100% that it is ToT before I do anything.

Yes, I shure you not need to install any software for use your VoIP-Box, but my questions is, if it would be possible to get a software for use on the computer from your VoIP-Provider only for test the connection with your ISP.

You also can connect any other LapTop with a VoIP-Software from any VoIP-Provider (like I use) with your router for try to isolate the problem.

Better go back to the roots first and if you can get a VoIP-Connection on this way try to connect more and more hardware until you loose the connection again - on this way you can find reason of your problem much more easy.

What about the old settings from BKK ? You still know them ? I think you not only have to open the required ports but forward them to the int. IP-adress of your VoIP-Box (TCP & UDP) - you made these settings already ?

If you like you also can take your VoIP-Box and visit me here for connect with TT&T maxnet. On this way you could find out if the VoIP-Box works with maxnet or not.

My hotel customers have no problem using VOIP with Skype from my ADSL connection. But I think Skype does not use port 5060 (correct or not?).

There are no 'settings' from BKK. The Dlink interface unit is a pre-configured box and I just plugged it in and it worked. Deecall will not give me the admin password for this box because they say there is nothing that should need changing.

On my ADSL router, I have opened and forwarded port 5060. But are there any other ports that I might need to forward?

Skype doesn't use that port, I believe it has configurable ports. But it also doesn't use SIP.

I don't even have port forwarding enabled at the office, wasn't necessary. And Deecall is being obstinate because they don't want you to use other services.

Tell them you want your money back, and see if they give you the admin password then. Either that or tell them to send a tech down to Phuket.

[Bagsida]

As far as I know Skype uses Port 80 and Port 41720, but shure different to the conventional VoIP.

With "settings from BKK" I mean the settings in your ADSL-Router or is it the same you used in BKK without any changes ?

Are you shure you forwarded (not only open !) Port 5060 to the internal LAN-IP-Adress of the DLink-Interface you get from Deecall with TCP and UDP ? And if yes are you shure the Deecall-Interface always have the same adress ? Which adress you gave the interface ?

Bagsida

[Bagsida]

...o.k. you not have the Admin-PW for the Deecall-Interface, so you not can set your own IP-Adress. The interface shure is set on DHCP-Mode for get the IP-Adress automatic from your router and so the adress may be not always the same. If you have forwarded Port 5060 to the IP-Adress the interface once had and this IP-Adress changed it´s forwarded to "nirvana" - may be this is the problem.....but not shure....have to see the configuration of your ADSL-router.

I found a weblog on Voip in Thailand ... have a look here : http://voipthai.blogspot.com/

To chancel the contract with DeeCall, reset the VoIP-Adapter and join an other service, would be a good idea - why not use this almost for free service http://www.voipdiscount.com/en/rates.html. They give you all settings you will need and can use the service also by SIP.

It works fine, not need a special converter and is really almost for free to Thailand, USA, Germany and, and, and....in the last 12 month I saved a lot of money with this Betamax-Company.

Bagsida

[onethailand]

I'm on voipdiscount at the moment - and have saved a significant amount of money already. It's not a perfect service but 120 days worth of calls have been pretty good so far. Will have to watch out for any change in plan... but frankly might also be smart to simply set up a new account.

Still like to know where Simon's problems are - normally it should not be the router unless it was provided by the ISP, in which case they may have custom settings.

[Bagsida]

Yes, I also heard about different problems with Betamax and the different brands of the them, but me myself never had any problems - not with free days nor with changing the promoted countries.

I own 3 different Betamax-Accounts. Two of the them I use with my PABX-System (SIP) in Germany to forward incoming calls of my office in Germany to my Thai-Mobile and one I use to make calls from my condo in Phuket (TT&T maxnet) to different destinations.

If Betamax would change something I not want to accept, I can change the provider and may be at the end I will loose my 10 Euros for get the 120 Free-Days, but in the time before I had all calls for free.

But o.k. if there is a way to clear Simons problems with DeeCall, it would be the best way - Simon himself have to decide what way he want to go and if he like, I will help him as far as I can do.
