E71 behind DSL router TG585V7 issues
 

I'll try to summarize my issue

I have 2 voxalot accounts one registered on the PC and one on the e71 on DSL behind a TG585 V7 router

1) I can register on both eyeBeam and e71
2) I can call from e71 to eyeBeam (voice is fine both ways)
3) I CANNOT call from eyeBeam to e71 i'm redirected to the voicemail
4) I also tried calling from another internet connection to the e71 behind the DSL router same thing not working
5) Finally from the e71 I can only call voxalot members, if i try to call someone at callcentric it directly gives "internet service not available"

can anyone help with these issues please

thanks

What do you mean by:
and in the same time
Did you mean you can call Voxalot's echo test at *600?
How exactly did you try to do that?
Are you using SIPBroker to dial or direct URI? What syntax you're using for this purpose?

I am sorry this is a mistake, I CAN from e71 to eyebeam (all is fine) but from eyebeam to e71 I'm redirected to voicemail as if the e71 was not registered

Good question i've just tested it 600 and 500 work but i CANNOT hear, from e71 to eyebeam audio IS fine

A friend of mine has voxalot account he tried calling me on the e71 and it didn't work (voicemail), he tried calling me on eyeBeam it worked.

from eyebeam i just call number@callcentric.dom the same thing does't work from the e71, no SIPBroker, I also tried using the iNUM number same thing

It could be that you've mistakenly placed your E71 softphone in DND mode. I often see people do that without knowing so by dialing certain codes or enabling it from their ATAs. In that regard check that your E71 isn't placed on DND in which case incoming calls are routed to your voice mail as you describe.

Second, it could be codec mishandling. It's possible the voice codecs on your E71 to fail to communicate with the server or end clients.

Trying calling different echo tests on different severs, for example:
*266301
*645904
*850301
See if you get any results.

Lastly, because you're behind a router the NAT handling with Eyebeam may not be as good as your E71. Perhaps you should post your settings so we can go from there. As last resort, you'll have to enter the web configuration of your DSL router and do some port forwarding.

The only reliable way to solve such problems is to analyze the SIP signaling on VSP side. Without seeing the SIP messages people can only guess.

Troubleshooting problems with Nokia it's necessary to keep in mind a few things:
- Nokia will use STUN automatically, but this may be changed from Nokia VoIP Settings application; depending on NAT device STUN usage may create a problem
- Nokia will always use source port 5060, if another SIP UA behind the same NAT router will use the same port this may create a problem
- Nokia creating INVITE message of quite a big size; this may create a problem with outgoing calls from it through SIP proxy, but this should not be a problem in Voxalot case (as Voxalot is running Asterisk which is B2B UA and not a SIP proxy); disabling codecs and switching to compact headers will not dramatically decrease the size;
- some Nokia models have SIP identity (From: field) hidden by default, this should be changed, http://forum.voxalot.com/voxalot-sup...html#post22139

It is VERY weird what is happening

First let me assure you it is not related to DND or anything however sometimes from the nokia phone (I've tried from a e71 and e66 same thing) i call the *600 and it works perfectly and sometimes (without changing anything) I dial *600 and i get no sound.

In all cases i cannot call a nokia registered to voxalot behind this dsl router

I think you might have nailed it i guess this is the error, anyway of changing that ?

I just changed the wording in my post. This port thing may create a problem and not 100% will. This really depends on the NAT device. Some devices will preserve the port number then others will assign the random port on WAN. Only the 1st case is potentially problematic. Anyway, you can always change a port on another device and let Nokia stay with 5060.

and what if i am using 2 nokias in my lan ?

Depends on your router & provider.
For example, one of my providers is accepting connections over both TCP & UDP, so I may use 2 Nokia's configured differently.
If your router preserves port then you're in trouble. If not - should be OK. Just connect to any SIP-provider who will show your registration status (address, port, UA) and compare the port with what is configured locally.
Alternatively you may check your eyeBeam log, you will obviously see your local port there and you will also see your external port with rport= statement in the server's reply). We had a long thread on this recently...

I'm not very good in this so I need your help :s

The router I am using is the TG585 v7 and the eyeBeam is working fine, my problem is with the 2 Nokias I have.

What should I check in my router?

If I call *0@proxy01.sipphone.com I get the "you are behind a sip compatible router" message

I'm not sure you can check your router directly.
But you may find all the information in the eyeBeam log file.

You may see port/rport discussion here.

If your source port will match rport value returned by the server - you're in trouble (with 2 identical SIP UAs).

Why not just do that and save yourself the trouble?

OK, what exactly will solve the problem? Which ports should be forwarded and where?

I am sorry Sleek I didn't understand what you mean ?
Can you be more specific ?

Moreover will installing a local SIP server (asterix or other) solve the problem ?

I didn't understand the E71 is crippled from configuration stand point, meaning pinpointing the root of the problem can be difficult at best.

In my opinion you can:
1. Consider installing an other softhpone client on your Nokia, one that supports better configuration and optimization.
2. I understand there's a .SIS package available for the E71 which provides additional features to the native SIP client, this might help. Google for more help.
3. Since your Nokia is using the 5060 port, change your eyebeam port to 5062 for example just in case.
4. Do you have web access to your DSL router? If yes, log in and place your Nokia on DMZ, this will forward all ports to your phone, then do some testing and see how it reacts, at least you'll know the problem comes from NAT-ing of your router and not the phone itself.

.SIS package (VoIP settings ?) will not allow to change the SIP source port.

eyeBeam is using random source port by default, this is configurable.

Having local IP PBX will definitely eliminate such problems. Alternatively any [external] provider which supports SIP over TCP should work without problems.

Having an other SIP client (eyebeam) working simultaneously with your Nokia may or may not be the source of the problem. You can assess that by turning off your eyebeam. If the issue persists while the phone is the lone SIP client in your LAN you'll know it's strictly your phone or your phone's inability to properly communicate with Voxalot's servers because of the NAT. As part of your troubleshooting actions, you could assign your E71 static IP and place it on DMZ from your DSL router. The other viable option is to seek better equipped SIP client for your phone which will have better chances to work under the circumstances. Personally, I think acquiring and supporting PBX for the lone purpose of having your Nokia phone working doesn't seem justified, but it's your time and money, plus it's not like you won't have your hands full if you haven't messed with PBX server before.

well this is getting very weird

registering the nokia to voipvoip i can call eyebeam and all is working

i'm pulling my hairs out

Now I am sure it is a voxalot issue

I opened 2 accounts with callcentric and everything is working fine without any changes
