Netcomm NB9WMAXXn VOiP keeps failing

[pauls]

Ok so who knows the right setup for this piece of rubbish as:
- When it is running good on the VOiP it decides to turn the voip setup off at random which means no
9c phone calls but full price
I have installed the new version which is (D111-S310NCM-C01_R10_20101129) which is the beta version, But when using VoiP

- The incoming call work and the phone rings and the reception is fairly clear

- The outgoing calls use to work fine without any distortion or computer interference, and now there

is static and computer squawk on the line all the time and makes it difficult to talk to anyone let alone hear them

I have done factory reset by reset button and turning off at wall and had to start fresh because after this there wasn't
anything there but the upgrade

New filter bought at dick smiths and phone cables supplied with your equipment also tested with other phone cables, still same problem

Also tried different handset still have problem, tried normal phone connected with wired handset, not hands free still same

Only 1 phone in use as with modern technology you only need 1 phone connected to phone line and all others work off aerials like mobile phones

and yes the one connected to modem has this problem as well
I like the cheap phone calls but this is starting to tick me off

It sounds as though you may be losing registration, although the squawk is novel. I have no experience of this new model, so I'll have to assume it's like the NB9WMaxx. When redoing firmware, always use an ethernet connection.

A few things to check over first:
1. Netcomm have a user config sheet at http://media.netcomm.com.au/public/asse ... Exetel.pdf although I would preferably use 58.96.1.2 as the proxy address (not sip1.exetel.com.au) and start with packetization time of 20 ms. 20 ms should not have to be raised for a normal speed service.
For comparison, the Exetel NB9WMaxx guide is at http://www.exetel.com.au/voip_pdf/nb9wMaxx.pdf. VoIP settings are there.

2. The Netcomm ADSL port must not be filtered, but the PSTN pass through line must be filtered, so if you use a Netcomm filter/splitter, check that the ADSL line is in that port, and the phone cable is in the other. There is a diagram on p7 of the user manual.

Workaround: The easy way to be certain that it can't send an expensive PSTN call is to unplug the PSTN phone line from the splitter! Obviously not a solution, as you can't receive PSTN either, but perhaps useful until you get it sorted. Plug another phone handset into the line for PSTN calls.

Thanks for your answer but does anyone actually have this unit working without any faults
Cause all of this has been done on previous attempts at getting this thing to work properly
I thought there may be something on the second page that needs to be changed on the advanced settin or
debug settings below is the first page
It isn't realy a squark it's more of a loosing conversation with the person you are talking to and it sounds like FAX static

Interface name: br0 - Bridgeppp_0_8_35_1 - pppoe_0_8_35

Local selection: AUS-Australia
Preferred codec list: G729 G711A G711U none none none

Preferred ptime: 20


Use SIP Proxy. Ticked

SIP Proxy: 58.96.1.2
SIP Proxy port: 5060
Registration Expire Timeout: 2040
SIP domain name: 58.96.1.2


Use SIP Outbound Proxy. Ticked

SIP Outbound Proxy: 58.96.1.2
SIP Outbound Proxy port: 5060

So does anyone have any answers or is this just too hard to solve????????
The two solutions above are strait out of the owners manual and still don't work.

Please try increasing the 'Register Expire Time' to 300 and check if this can be resolved.

[pauls]

Well I tried this ''Register Expire Time' to 300 " but it only made the conversation clearer for about 2 minutes
and then went back to the hard to hear the conversation

Maybe I should buy a new modem/router thingy

[CorporateVoIP]

Your config looks ok. Can you try a factory reset and when setting up VoIp again, only use G711A, nothing else.

As said, leave the PSTN unplugged whilst doing these tests so you are sure it's not being routed somewhere else.

[pauls]

Excuse my ignorance, but what is a PSTN and what is this going to solve by leaving it unpluged
Done all factory resets but still plays up
Haven't had any probs for few weeks and then upgraded new firmware to new one to R11 and then it all
comes crashing down again
Netcom suggested that I send the modem back and pay freight to them both ways $35 each way
and they will check it out and see if it is working correctly, won't send me a new one first and then I send
them the old one( already changed telstra to $20 plan)
They do all upgrades if i'm on tpg or some other companys but no help for me on extell
So does anyone use Draytec? modems and do they work??????????????????????

[Dazzled]

PSTN is the standard phone - the cable runs between "Phone" on the splitter and "Line" on the modem. The Netcomm has fallback to PSTN. CorporateVoIP is asking you to unplug it at the modem, so you can be certain you are only testing VoIP.

Draytek modems and routers use high quality components, and are expensive to match. A Draytek Vigor model with VoIP included would set you back from $275. There have been posts here from users.

.......... what is this going to solve by leaving it unpluged

You wont have those 'expensive' phone calls
and as above you can test out your voip.

You sure summed up very well about the 'NB9WMAXXn' in your opening post.

Ok so who knows the right setup for this piece of rubbish...

Some further questions:
What is the speed(plan) of your internet connection?
What type of phones do you have plugged into your 'Maxx' (Brand and Model)
If you have an ADSL2+ connection, Do you have ADSL2+ filters installed on your phone line?

[pauls]

What is the speed(plan) of your internet connection

1.5 /256

What type of phones do you have plugged into your 'Maxx' (Brand and Model)

PANASONIC N52, KX-TG8321AL wirless phone with base pluged into Netcom Voip at back where suppose to and
3 wireless handsets, also had normal corded phone plugged in with same problem, voip is suppose to work with these handset phones
as a friend has the telstra hub plan and the phone she uses is a cord free!

If you have an ADSL2+ connection

No ADSL 2 available where I live in Central Qld

and are expensive to match. A Draytek Vigor model with VoIP included would set you back from $275

A friend has one of these Drayteks and is on exetel and doesn't have the probs i have, and I paid $250 for the modem I have at hardley normals

CorporateVoIP is asking you to unplug it at the modem, so you can be certain you are only testing VoIP.

At present the R10 version that is installed worked for 1 day then has decided to stop all incomming calls and make the line busy( engaged)
Ok I did this just to try it using the handsfree phones,will do upgrade of R10 and try again and send results
- If I try to ring my mobile it rings and I can answer but there is no voice if I talk into either phone
-If I try to ring in using my mobile the phone doesn't ring at all
-I also have a normal plug in corded phone (a uniden on for $20) that is plugged into a wall socket (no wherere near the modem) so that I can make 1300(cheeper than exetell this way) and have a phone if the power goes out so we can make phone calls, it has a splitter so it will get a dial tone.At present
this one will ring with the PSTN unpluged, but the Panasonic ones don't
What does this prove by unplugging the PSTN?
I have asked Netcomm for the R10 version that I use to have and am waiting for it to arrive by email, at least it sort of worked

[Dazzled]

Panasonic cordless phones with multiple extension handsets work perfectly well with Exetel voIP. The corded phone plugged directly into the wall should be filtered. A simple inline filter will do.

The original problem was VoIP dropping, forcing you onto the PSTN fallback. The point of unplugging the PSTN line from the Netcomm is to get rid of fallback to make diagnosis of the VoIP drop a bit easier. You won't get accidentally stung financially for the calls either. It might be useful to set the Status-System Log log level to Notice, or even lower (but not debug!). When a drop occurs if you read the log soon enough after, the full chain of events as seen by the VoIP hardware will be displayed. There may be a clue there in the stream of alphabet soup that emerges.

I hope the separate PSTN-only phone is filtered, because otherwise noise from it could cause a VoiP packet error in the Netcomm.

I would suggest you use specialist dealers for modems and network equipment (many are online shops) - the NB9WMAXXn can be bought that way for about $170 up, well under the good Draytek price I mentioned earlier, and the staff are usually far more knowledgeable if you have a question. See for example http://www.jmgtechnology.com.au/index.php?cPath=89_90

When I bought mine last year in September all the online stores and even hardley normal were all around $280 and I thought that I was getting at a good price for $30 cheeper,but that was 6mths ago
Same old problem with this piece of crap, it works for 6 hrs then goes to sleep and wakes up not remembering what it is and wont receive any phone calls say's engaged when you ring from mobile

[pauls]

Netcomm finally released the right stuff to make it work properly maybe?
Quality of Service (QoS) Setup for VoIP
(NB9WMaxxn}
Under there self help guides there is the following, yey it worked for 1 day and now doesn't
ring again
Piece of crap

[peterh_oz]

Sounds like a faulty product.

I had one of these when they first came out, it kept dropping connection. However there have been a couple of firmware updates since, and I have other customers using them with no issues.

I would suggest the following:

Disable any bit torrenting or uploading. If in doubt, turn off your PC. No you don't need to permanently, but do so for testing to eliminate it as an issue. QoS means it shouldn't be an ussie anyway, but lets just make sure.
Unplug the PSTN (as described above) - again, temporarily for testing, to eliminate the calls falling back to Telstra, and you assuming "oh they're good now".

If the problem continues then contact Netcomm support and get a replacement.

The NB9WMAXX is a great modem, rock solid. The newer NB9WMAXXn should be just as good, so maybe you have a faulty one. Look at it this way: if they were all like that, no-one would buy them.
