Well back from my travels yet again, so again its time to try and get this dam teleworker working.

So, we have swapped out the previous handset for another 5312 that was working on the system fine.

Phone configured in Teleworker mode with the remote end WAN IP
Phone has been configured for NAT mode
Server has the relevant WAN IP in the relevant places
Mitel 5000 unit is in the DMZ on the remote end.
Various ports opened on either end (Previous to putting 5000 in DMZ)

Current state:  Teleworker phone boots and connects fine from remote location.  All correct relevant info is displayed on the screen, Ext, Phone ID, Date & Time

From the teleworker phone; I phone an extension on the system.   I can hear them.   They cannot hear me.   Same applies if the remote end initiates the call.

The 5000 end of the network is using a Draytek Vigor 2820
The Teleworker end is using a Draytek Vigor 2830

Both have recent firmware on.

I am now scratching my head where the issue could be, so any advice from out there in "Mitel Land" would be very much welcome in order to restore my sanity.


Thanks.

Have you tried defaulting the Drayteks back to factory ( or would that be too complicated). I had issues like this when I was trying to get my MBG on a 3300 to work (its simple really but I had messed about that much with it...). I defaulted the router (2830) and set it up as was with the username etc. and did the routing bit (and turned off sip on the command line) and bingo it worked first time.

Its so easy to change something on these routers and mess them up they are so configurable.

Unfortunately that would give us a headache as currently we are working remote and would have no way of getting back into the router unless we were at the remote site :-(   but very confident nothing else has been changed, pretty much left "as-is" out of the box.

Had two of confirm all the settings, and that SIP_ALG is off on both ends.   We are just waiting to get someone to hook up a laptop at the remote end so we can run the network qualifier to see if that throws any light on the subject.

I do appreciate the suggestions and information, all to easy to "miss the obvious" sometimes :-)

I am not familiar with Draytek routers so I am of limited help.

Is there other firewall rules in place on the router? It sounds like there could be some really restrictive rule on outbound.
Disable firewall rules if applicable.

Do you have other routers that you could try? Or maybe try the VPN tunnel.

The crazy thing is that there are no other firewall rules.   In fact yesterday afternoon we disabled the firewall on both ends for a short period and it never changed anything.    Really am getting frustrated with something that should really be plug n play with some minor adjustments of the ports.

Just seems that no matter what we try, it makes no difference to the system.   Even gone to the extreme of adding additional open ports that control other elements of Mitels, and still no luck,

As you can see from the logs above, it connects - communicates then seems to block the incoming voice packets, outgoing is no issue.

Going to stick a PC on the other end and run the "network qualifier" to see if that shows up anything......But for now I am stumped.

I wouldn't worry about putting phone in DMZ, just have it NATting normally.

Remove all port forwarding from system router and put system in DMZ, leave remote phone behind NAT. Test and see what happens.

Okay removed all open ports.
System placed into DMZ
Remote phone removed from DMZ and just NATing.

Result was that we lost the audio coming from the system end . (Originally, on the remote phone, I could hear the system end, they could not hear me)

Place phone back in DMZ .  I can hear the system end, they cannot hear me

mmm... thinking a bit differently now, do both Draytek routers support VPN.

Could you just setup a VPN between all sites?

Also looking at your port forwarding it looks like entry 6 is forwarding most UDP ports 6000 - 60000, is this your intent?

VPN was our next thought.   Entry No 6 was just a test.....If I recall, at the moment we are just trying to expand what we have to see if it has any effect.   Nothing we seem to do makes any difference.

when looking at the Syslog from the Draytek you can see when the call is made, starts off ok, but the second the call is answered the log is flooded with "User: 192.168.1.201 -> 192.168.3.10 (ICMP) Destination Unreachable"

both routers can ping each other with no problems.   And we thought by putting the phone and the system in the DMZ it would solve the problem.......but we were wrong again.

So now just banging heads against the wall!!!!!

Have you checked the SIP Alg from the command line? My guess is still the SIP_Alg if its not been done from the command line.

Yep checked from command line and SIP_ALG is off on both ends.

Just to confirm the "Open Ports" on the System end, we have probably gone to the extreme after scanning every tech document we could find, but we can always remove later once its working.   The following have been opened:





Also, ran Syslog on the remote end whilst making a call to the system end (192.168.1.202) the following is the result:

Okay guys, I have:

System on DMZ
the phone on the remote end on DMZ

Still only one way traffic I can hear them (system end) they cannot hear me (remote)

On the Draytek's on both ends, have checked sip_alg and both confirmed as disabled.

Both ends are running across ADSL and both have 6mb down and 512k up.  Currently no network issues, and the half of the call we do get is good quality.

Any more suggestions :-(


Thanks for your input.

Thanks for the advice guys.

I have checked the two places on the Mitel;

System\IP Settings\System NAT IP Address
System\Devices and Feature Codes\IP Connections\P6000\NAT IP Address

Both settings have the same WAN IP address

on the remote phone have changed it to NAT

Router is a Draytek 2820 and have the open ports set as per the attachment:



Still no voice........


On the phone I have set the ICP to the WAN Address and in Teleworker mode given the WAN Address.

Thanks

Graeme

Well finally got round to installing and testing this.   On trying it through the normal method we add the Mitel's to the system, previously defining ICP on the phone to the NAT address of the system, I continually got to DHCP then the error "Option 128 Missing".

So tried with the pressing 7 and putting the handset to teleworker mode, this worked fine, got an address from the system and applied the extension number.   So happy about that.

BUT,

On using the remote extension I have found:

     1.  I can ring internal extension numbers fine.  but when ringing external numbers I just get silence.  The display shows as if the call
     is connected and you can see the countdown timer running......but total silence.

     2.  When I dial an internal extension and it hits Voicemail.   I can see the voicemail recording counting up, but I don't hear the other
     ends voicemail initial speech.

Any ideas where I might have slipped up ?


thanks

Yep still in the North-east and still into I.T, although I now cover from M4 Gloucester up to the Shetlands and across to Belfast :-) just a small area.  I will keep you in mind on the Mitel side, although you know my supplier "Graham - Online Unified" ;-)

yes you need to set this NAT IP address up to be you external IP address as well.

Yes I'm in Peterlee, which Graeme are you then? I know about four who are spelt that way?

Thanks Ralph.

I was the I.T Manager at "Northern Training Trust" all those years ago :-)

(I'm really being good here stopping myself from reconfiguring my 5312 to your external IP and trying to guess some passwords  )

d95gas, take the hint here and edit your screen shots.   Hate to see you get hacked.

Ralph

Thanks Dave.   I would alter the Image BUT, for some reason I dont have the ability to edit my own posts :-( have asked Ralph to do the necessary.

And if you are the person I think you are :-) I know you are a good lad and would'nt do such dirty deeds :-)   You in Peterlee ?

the NAT Address I missed:  is it the one where it currently states 255.255.255.255 ??

Our system engineer either put that in or it was defaulted on install, hence I left it, So you are saying I need to change that for the WAN IP address (NAT) ?
