Siemens SL685IP & DrayTel - no audio?

Hi there,

I have a Siemens S685IP that has Gigaset.net & Sipgate accounts that seem to
work as expected...well OK nobody to call yet(!) but dialling Sipgate 10000
or Gigaset 1234 reveals pre-recorded messages so for now I shall assume this
is working OK!

I have added a DrayTel account which has registered and allows me to dial
various service/test numbers such as;
9123 - Speaking Clock
9200 - Voicemail
901-907 - Various other services etc.

Dialling any of these numbers connects to the server and shows the call
timer incrementing as if in a call but I hear no audio whatsoever!

I suspect a couple or three things that might be causing this;

1 My router might be filtering out the audio (although the other accounts
work as expected)
2. Possibly a setup issue in the 685IP on the DrayTel account?
3. The phone may not be transmitting DTMF/SIP to the server (is this
possible as it does connect?)

Has anyone trod this path before or can some kind could point me towards a
resource that explains how to set up a DrayTel account on a Siemens S685IP
please?

Ports already forwarded to the 685IP include;
Port 3478 TCP/UDP
Port 5004 - 5020 UDP
Port 5060 TCP/UDP
Port 5065 TCP/UDP
Port 5222 TCP

Have I missed something fundamental here?

1) *Please* remove all ports forwarding, you don't need *any* of them
for your setup;

2) Check that no SIP ALG (Application Layer Gateway) is enabled on your
router. If yes disable it. Google for your make and model if there's no
obvious way to check / disable it. The damn thing is more harm than good
in 99.99% of the cases.

3) If the router has a VoIP section, do your utmost to disable it
completely. If you can't, move all ports for all settings well away from
5000-5100.

4) *Always* set an outbound proxy in all accounts. For Sipgate, the
setup I use is:

General Provider Data

Domain: sipgate.co.uk
Proxy server address: sipgate.co.uk
Proxy server port: 5060
Registrar server: sipgate.co.uk
Registrar server port: 5060
Registration refresh time: 600 sec

Network

STUN enabled: [X] Yes [ ] No
STUN server: stun.sipgate.co.uk
STUN port: 3478
STUN refresh time: 999 sec
NAT refresh time: 999 sec
Outbound proxy mode: [ ] Always [X] Auto [ ] Never
Outbound proxy: sipgate.co.uk
Outbound proxy port: 5060

As per Draytel, never used them but I gather their outbound proxy is
"nat.draytel.org" on port 5065.

See here:

http://www.draytel.org/resources/ima...ens_S450IP.gif

As DTMF method settings, have enabled *only* the RFC2833.

It'll be £ 10 + VAT for the consultancy, who do I send the invoice to?

Thanks for the quick & comprehensive reply Bodincus,

From the top;

1) I have now disabled all open port forwarding to the S685IP

2) SIP ALG was already disabled. I had checked previously via Telnet using
the sys sip_alg ? command line and it returned a 0

3) I have now removed entries for Sipgate & DrayTel from the 2820Vn VoIP
section. Ironically it was the DrayTel account that was showing as
registered in the router while the Sipgate was not!

4) Why would I *Always* set an outbound proxy if using STUN on Sipgate for
example? I would prefer to use STUN for everything but DrayTel don't support
it. I am new to VoIP so please be gentle with me if I have misunderstood!
:-)

My Provider data for Sipgate is similar to yours apart from my having lower
refresh times than 999 and having 'Never' checked for Outbound proxy mode as
it uses STUN

I have followed your recommendation for using the DrayTel Outbound proxy as
per that difficult-to-read picture from DrayTel themselves and changed my
Send Settings from Auto to RFC2833.

I still can't hear any audio but now in addition I can't even get the
DrayTel account to connect...it sits there a while and then gives Error 701.
At least before it connected and the timer incremented despite my not
hearing anything.

If I disable the Outbound Proxy mode then I can again connect...but back to
square one as still no audio can be heard.

Consultancy fee? No problem...give me a call...via DrayTek VoIP and you can
tell me where to send the cheque ;^)

Valiant attempt...I appreciate your help.

Thanks & kind regards,

OK, well done.

So this is a VoIP enabled router, and you are using it to register with
the providers? And you want also to have a Siemens behind it working? 8-O
Sorry, you can't, if you don't change drastically all ports on one of
the two devices, the SIP or RTP traffic will go to the VoIP section of
the router and your Siemens will be none the wiser.
To keep things simple, either use the router or the Siemens.
Yes, it's possible to have them to work together, but it's a step too
far with your - let's face it - restricted knowledge of VoIP and my
restricted free time.

No, STUN is NOT a replacement for Outbound Proxy.
STUN serves the purpose to let the Siemens know what is his real,
external IP and then use it in the SIP messages. This helps a lot for
signalling, but doesn't affect the RTP (audio) traffic.
Any device between a NAT has no way to know that it is, if you don't
give it a way to tell his *real* IP is not the one he knows.
Siemens phones need STUN to understand this, and they use the external
IP according to the RFC even when registering through an OB Proxy.
Please have faith, and use the settings I have sent you, I've been using
them for years: they work a treat for me and a dozen of customers I have
around the UK with Siemens phones.

> I have followed your recommendation for using the DrayTel Outbound proxy as

Yeah, really shoddy work there

> and changed my Send Settings from Auto to RFC2833.
That's how I have it in mine, with 5 different providers registered.

701 is not a SIP standard error. What can you see from the web
interface? Does it say "Registered"? What else?
I think that if you don't take the router out of the way (changing its
ports out of the 5000-5100 range) you won't have any luck.
let me see if I can find a easy way out...
<off to google>
AAARRGGHHHHHH! That router does too many things for my liking.
It's *really* too complicated to have both that router and the Siemens
working together.
It'll be too time consuming and a kludge. I give up. Sorry, but you
bought either the wrong router to have a VoIP phone behind it, or you
didn't need a VoIP phone in the first place.
With that router, buy two DECT handsets and use the router phone ports.

> If I disable the Outbound Proxy mode then I can again connect...but back to

The audio (RTP on UDP) and the signalling (SIP on UDP) are two
completely different pipes of traffic, one can get through and the other
does not.
I forgot to add, if you have any anti-DDOS or UDP flood setting enabled
on your router (it's usually in the Firewall section) disable it.
The audio RTP traffic is usually seen as an UDP flood and the firewall
blocks it.
But I can't see any light out of the tunnel for you, I'm afraid.
You need to bite the bullet and change any of your devices.

Hello again Bodincus,

1) :-)

2) :-)

3) I only enabled the VoIP in the router when I couldn't get DrayTel to work
in the S685IP. As I said above I have since defaulted it to off to prevent
any 'interference'.
The more I delve into it the more I learn...understood & thanks for your
insight.

4) Believe me I have (am) persevering! Interestingly DrayTel this morning
have sent me a much clearer, S685IP specific screenshot if you might want a
copy to make it easier for you to help others?
The DrayTel does show Registered. Interestingly (or not) the Error 701 only
appears when I have Outbound proxy mode set to Auto or Always On. If I set
it to off I get connected and the call timer works. Set to Auto or Always On
and I get a visit from Error 701. Go figure...I see you have discovered the
joys of setting up the 2820Vn then? <chuckle>
As a last resort I might be able to press the NEC XN120 into VoIP duties but
figured the S685IP would be the easiest option...yeah right...I am going to
run the Siemens course as I really want the S685 to be a one-stop handset
and as the router is in my rack in the loft I do not want to be tied to the
end of a Cat6 cable to make/receive VoIP!
It is easy to disable the DoS Defence setup including UDP Flood Defense but
that made not one iota of difference surprisingly...the theory was good
though...I thought we might have nailed it!

Thanks again for your valued time & trouble.

If I ever get it working you will be my first VoIP call to a human being ;^)

Thanks & kind regards,
-=Glyn=-

You are posting right at the bottom of the posters reply which is
correctly formatted with a signiture block separator of two hypens "--"

Many newsreaders wisely ignore all information beyond this separator so
when you post after it your comments may not be visible to some readers.

Best thing if replying to a multi-point post is do as Bodinicius does
and reply between subsequent points with your response to those points
then you can delete the rest of the un-related stuff before re-posting.

Just a thought.

Change the VoIP ports in use in the router away from 5060-5070 in each
account even if you're not using the accounts

Hi Jono,

Thanks for the reply...I had already tried that.

After some excellent support from DrayTel (including my first ever (and up
to now - only) incoming VoIP call it is now working! :-)

Part of the problem I think may have been down to the number I was
dialling - 9123 for the speaking clock (according to the DrayTel online
Help) which I am told is not working! <blush>

Thankfully to save my total embarrassment that was not the only issue -
according to DrayTel;

"The issue appears to be with the registration request, initially IP phone
was sending request using private IP address, then I clear registration
from your SIP ID and the phone registered, which seems to be fixed issue."

Sounded like an initial proxy configuration error at my end?

The Error 701 was the handset code given when the called party hung up -
like when dialling an out-of-service number maybe?

Just wanted to post this in case any others have the same issue and in
recognition of those (especially Bodincus) who offered help & advice...much
appreciated guys!

I now have Sipgate, DrayTel, GismoTel & VoIPtalk to evaluate - or will just
as soon as VoIPtalk respond to two help tickets raised as to why I cannot
connect either by S685IP or Softphone on iPhone via Wi-Fi or 3G.

I thought this was the easy route into VoIP with the S685IP but it has not
been without its trials & tribulations - I thought I would start here with
VoIP as a pre-cursor to configuring my NEC XN120 VoIPU card but I might just
give that a miss now! :-)

Thanks & regards,
-=pp=-
