This is a sip number if you are using exetel voip to call.

Yes, that number does in fact work.

So the problem appears to be in relation to numbers I dial which are routed to the Exetel VOIP PSTN gateway. I wonder why this is not working with the 2700VG.

I dont think your Draytek 2700V has a Voip-->PSTN gateway.
The only device I know of that has a Voip-->PSTN gateway is the Linksys SPA 3102.

Sorry, what I meant was Exetel's VOIP gateway. The 2700VG has a FXO "lifeline" port, connected to the phoneline via an ADSL filter, which means the unit's ATA is bypassed when power fails or you opt to dial out via POTS.

Ok, what I have done is open a VOIP account with FaktorTel, I'll see if there's any difference there which should isolate the problem further. They'll need to clear my CC details before I can dial out via their PSTN gateway, which I imagine will be tomorrow sometime. I'll report back the results.

To test your dial out via this FXO port turn off the power to your ATA and see if it dials via PSTN

You still need to set a dial plan for PSTN setup to opt to dial out on PSTN,
see page 110-111 of user manual.

You need to set dial plans to get voip to dial to a 'DID' (PSTN) number.

The results with FaktorTel. Works just fine. I can dial any POTS number, rings through and we talk, no problems.

My VOIP related settings are exactly the same for both Exetel and FaktorTel, only the account details differ. That is to say, I copied my Exetel VOIP settings when I set up my 2700VG for FaktorTel.

One kind user offered me his Exetel DID number to try but that did not ring either, same "SIP/2.0 408 Request Timeout" response from the SIP server as well.

What does work with Exetel/2700VG is the 121 Voicemail service and the 1300 788 141 number.

What is not working is an Exetel 8205#### DID number and any POTS numbers I have tried.

There appears to be a compatability issue between the Draytek 2700VG and the Exetel SIP server, I think I'll need to raise a ticket for this one.

I don't wan't to dial out via the FXO port, I want to dial out via the Exetel VOIP PSTN gateway.

Not necessarily, you can force an FXO dial-out by pressing #0.

No, you don't, you just dial the number you want. No need to set up dial plans or anything similar. Don't worry about the manual, it's confusing at the best of times. Even Draytel Aus/UK websites have guides to "decipher" the explanations in their own user manuals.

Does it make any difference when you dial the area code before the number?

This is because your hardware has a preset dial plan for#0,
You can probably get the same result by hook/flashing.

I disagree.

I would suggest some further reading on this matter.

No, the area code makes no difference.

Whatever nomenclature you wish to use, there is not a dial plan for this listed. There are no dial plans listed at all by default.

No.

No. Works just fine without any dial plan via FaktorTel, as I indicated yesterday. You simply just dial the number, as one would expect. No dial plans.

Well, I guess you know it all then. I have already stated this is not the case. I suppose it was all in my imagination when I spoke to my wife yesterday via FaktorTel VOIP. No dial plans.

These threads are quite old. I have not experienced the problems described, undoubtedly Draytek have resolved these issues meanwhile. The current firmware for the 2700VG is V2.7.3.1, build date 17/09/07.

I dont claim to know it all.
You are the one requesting HELP, from your original post.
If you have the answers from Draytek and elsewhere why bother posting here?

Hi,

With the help of Draytek I have found the solution to this problem.

In the VOIP->SIP Accounts settings page there is a "Display Name" field, which the User Manual only describes as "The caller-ID that you want to be displayed on your friend's screen". However, there is more behind the scenes than that. The text entered in here affects the messaging to the SIP server.

For example, "John & Jill Smith" entered as the Display Name would appear in the From: field of the following registration dialog to the SIP server:

Code: Select all

-->Send Message to 58.96.1.2:5060 <11:47:42>
REGISTER sip:sip1.exetel.com.au SIP/2.0
Via: SIP/2.0/UDP 220.233.###.###:5060;branch=z9hG4bK-Ygn-20020;rport
From: John & Jill Smith <sip:09######@sip1.exetel.com.au>;tag=bhX-25417
To: <sip:09######@sip1.exetel.com.au>
Call-ID: isD-13469@220.233.###.###
CSeq: 100 REGISTER
Contact: <sip:09######@220.233.###.###>
Max-Forwards: 70
Expires: 240
User-Agent: DrayTek UA-1.2.3 Vigor2700 Series 2.7.3.1
Content-Length: 0

The problem all along has been the "&" character in the Display Name. If I delete this or change it to "and" so it no longer appears in the From: field I am able dial POTS numbers via the VOIP PSTN gateway without problem.

So there you have it. While the FaktorTel server is happy to accept "&" chars, Exetel's isn't. Go figure!

Oh, one other thing. I contacted voip@exetel.com.au last Wednesday (1.12pm) to raise this issue and have not received any response. Is that normal? I had hoped for an acknowledgement within 48 hrs. at least.

I'll be happy to pass on what I've found, but I assume I will need a ticket number to respond with?

Howard · Post by **Howard** » Mon Oct 15, 2007 12:46 pm

The ticket was opened using cc: field, which i through you were just want to copy to exetel as information, as a result, i didn't respond to your ticket.

stevebow · Post by **stevebow** » Mon Oct 22, 2007 9:27 am

The message was addressed to voip@exetel.com.au but CCed to Draytek Support to keep them in the loop as I had been discussing the issue with them already.

In any case, the source of the problem has been found (my post above). Thanks for the help.
