Granstream GXP-2000 De-registering Problems

#1
Hi

I have set up an office with 10 grandstream GXP-2000s and am suffering from the de-registration problems others have reported. On some days certain phones require re-booting 5 to 10 times which makes the system effectively unusable.

I have upgraded firmware to 1.1.1.14 to no avail. I have tried increasing reistration interval to 4 minutes. Nothing has helped.

Can anyone advise what is the current wisdom on this issue ?

Many thanks,

David

Hi David!

Yes de-registration problems can be annoying, we suffer from them, but i hink we have found the source of the issue now and are trying to correct, even though we do not use the grandstreams.

Suggestions/Questions:

What router do you use? Is it SIP aware?
Have you tried enableing STUN e.t.c?
Do you use the nat proxy? Have you tried removing it?
Have you set the reregister time to 60secs?
Do you have the same issues with Xlite?

Charlie :)
If you got any questions I'll be happy to help. Just don't ask me about VoIP, i know so little about that i'd bore you trying to talk about it, but we all have to learn sometime!

Hi Charlie,
  • I am using a Draytek Vigor 2800 which I believe is SIP aware.
    I haven't turned on STUN - I didn't think this was appropriate here - thought that was more about NAT traversal and one-way audio ...a problem we don't have.
    I have tried with and without the nat proxy
    Re-regiuster has been 1 min, 2 min and 4 min - no improvements
    I will try with X-lite.
Thanks for your input.

David

I've set up a syslog to record the messages from the Grandstream as it loses registration. I am not a VOIP expert so was hoping someone could tell me what's going on - seems as though voipfone are giving me a 403 forbidden which is causing the grandstream to stop bothering to re-register.

Here is a successful registration :-

GS_LOG: [00:0b:82:0a:59:09][000][FF71][0101010E] 956 REGISTER sip:sip.voipfone.co.uk:5060 SIP/2.0 Via: SIP/2.0/UDP 10.0.0.9:5060;branch=z9hG4bK41ef87094c2208cc From: "David Lewis" <sip>;tag=a392320924d412e0 To: <sip> Contact: <sip> Authorization: Digest username="30124953*201", realm="asterisk", algorithm=MD5, uri="sip:sip.voipfone.co.uk:5060", nonce="3989ba16", response="ccea707fb6c3ade2ae4bf0c66d62a2aa" Call-ID: 63c085ababbb7d1c@10.0.0.9 CSeq: 10085 REGISTER Expires: 3600 User-Agent: Grandstream GXP2000 1.1.1.14 Max-Forwards: 70 Allow: INVITE,ACK,CANCEL,BYE,NOTIFY,REFER,OPTIONS,INFO,SUBSCRIBE,UPDATE,PRACK,MESSAGE Content-Length: 0

with the voipfone response :-

GS_LOG: [00:0b:82:0a:59:09][000][FF71][0101010E] 195.189.173.10:5060 5060 573 SIP/2.0 200 OK Via: SIP/2.0/UDP 10.0.0.9:5060;branch=z9hG4bK41ef87094c2208cc;received=81.86.137.19;rport=5060 Record-Route: <sip> From: "David Lewis" <sip>;tag=a392320924d412e0 To: <sip>;tag=as69f1cd4f Call-ID: 63c085ababbb7d1c@10.0.0.9 CSeq: 10085 REGISTER User-Agent: Voipfone Sip Network Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER Expires: 60 Contact: <sip>;expires=60 Date: Sat, 25 Nov 2006 16:58:05 GMT Content-Length: 0

Then, a minute or so later, the grandstream seems to send out two register messages :-

GS_LOG: [00:0b:82:0a:59:09][000][FF71][0101010E] 956 REGISTER sip:sip.voipfone.co.uk:5060 SIP/2.0 Via: SIP/2.0/UDP 10.0.0.9:5060;branch=z9hG4bK8d98c33442ffcc8e From: "David Lewis" <sip>;tag=a392320924d412e0 To: <sip> Contact: <sip> Authorization: Digest username="30124953*201", realm="asterisk", algorithm=MD5, uri="sip:sip.voipfone.co.uk:5060", nonce="3989ba16", response="ccea707fb6c3ade2ae4bf0c66d62a2aa" Call-ID: 63c085ababbb7d1c@10.0.0.9 CSeq: 10086 REGISTER Expires: 3600 User-Agent: Grandstream GXP2000 1.1.1.14 Max-Forwards: 70 Allow: INVITE,ACK,CANCEL,BYE,NOTIFY,REFER,OPTIONS,INFO,SUBSCRIBE,UPDATE,PRACK,MESSAGE Content-Length: 0

and

GS_LOG: [00:0b:82:0a:59:09][000][FF71][0101010E] 956 REGISTER sip:sip.voipfone.co.uk:5060 SIP/2.0 Via: SIP/2.0/UDP 10.0.0.9:5060;branch=z9hG4bK8d98c33442ffcc8e From: "David Lewis" <sip>;tag=a392320924d412e0 To: <sip> Contact: <sip> Authorization: Digest username="30124953*201", realm="asterisk", algorithm=MD5, uri="sip:sip.voipfone.co.uk:5060", nonce="3989ba16", response="ccea707fb6c3ade2ae4bf0c66d62a2aa" Call-ID: 63c085ababbb7d1c@10.0.0.9 CSeq: 10086 REGISTER Expires: 3600 User-Agent: Grandstream GXP2000 1.1.1.14 Max-Forwards: 70 Allow: INVITE,ACK,CANCEL,BYE,NOTIFY,REFER,OPTIONS,INFO,SUBSCRIBE,UPDATE,PRACK,MESSAGE Content-Length: 0

And voipfone send back the forbidden response:-

GS_LOG: [00:0b:82:0a:59:09][000][FF71][0101010E] 195.189.173.10:5060 5060 473 SIP/2.0 403 Forbidden Via: SIP/2.0/UDP 10.0.0.9:5060;branch=z9hG4bK8d98c33442ffcc8e;received=81.86.137.19;rport=5060 From: "David Lewis" <sip>;tag=a392320924d412e0 To: <sip>;tag=as18f54a65 Call-ID: 63c085ababbb7d1c@10.0.0.9 CSeq: 10086 REGISTER User-Agent: Voipfone Sip Network Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER Contact: <sip> Content-Length: 0

Any ideas what is happening ?

A quick look through the SIP RFC states the follwing :-

quote>>>>>
21.4.4 403 Forbidden

The server understood the request, but is refusing to fulfill it.
Authorization will not help, and the request SHOULD NOT be repeated.
unquote>>>>

This suggests to me that the 403 response that voipfone gave is causing the grandstream to stop trying to re-register as per the standard. So why did voipfone send out the 403 ?

I am starting to feel a little dispondent about the Voipfone support. They don't seem very interested in looking at the cause of this problem.

Can anybody recommend an alternative with features as good as voipfone but with some support ?

There are many, many resons why your phone is giving NR; I suggest you read this if you haven't already done so.

http://www.voipfoneuserforum.com/viewtopic.php?t=1058

Both Grandstreams and Vigors are problematical - you need to be sure that you have their latest firmware fixes.

Additionally error 403 can be caused by an incorrect phone configuration. You will find a wizard here:

Failing that, I suggest you email support at voipfone.co.uk for further assistance.

I have checked through all of your guides. And I have also emailed support but have had very slow response.

I have the lastest grandstream firmware and don't believe it to be a problem with the Draytek Vigor as I have the same problem through a different router (netgear).

I am getting to the point where my client is going to have to replace the 10 grandstreams he bought with Snoms or move away from voipfone (which is a shame as the service meets his needs in all other ways).

Can someeone please help me. Does anyone have grandstream's working reliably on voipfone ?

Thanks,
David

Not sure if it's too late for this thread but I too had a Grandstream with deregistering problems. Without going into the details, sometimes Voipfone and Grandstream don't get on.

A sledgehammer solution is to buy an Intertex SIP-aware router, which means that you can forget about NAT and all that stuff - which is a Somewhat expensive but it works. My Grandstream now works fine!

Grandstream GXP and UNREGISTERING with VOIPFONE

#10
After a major battle with the problematic situation of VOIPFONE accounts unregistering with a GRANDSTREAM GXP phone. I might, just might have cracked the problem. At least with my ZyXel 600 series router.

I believe it is a random port problem. The experts out in cyberspace can shoot me down if I am not making sense.

I opened all ports to the static network IP address of the GXP 2000 in the ZyXel router NAT web browser using the SUA only configuration. This cured the VOIPFONE accounts from dropping out. Great I thought after 48 hours without any re-booting of the Grandstream phone. Then my daughter arrived back at home.... There was a cry from her bedroom ' MY INTERNET CONNECTION DOES NOT WORK WHAT HAVE YOU DONE TO MY LAPTOP..... The answer was actually nothing.... Strangely ICQ and SKYPE were working but not the Windows Explorer web browser. I was able to access all my web functions on my personal computer so I was surprised at this sudden shout from her bedroom.

OK the only parameter changed onthe Zyxel router was ' OPEN ALL PORTS ' to the fixed IP address on the GXP phone.

I deleted this setting. My Daughter was whooping with joy, her web browser was working again.

Immediately the VOIPFONE accounts started to drop out randomly.

So what to do now..... I then went to the FIREWALL settings in the Zyxel web browser and made a RULE for both Local Net to Internet and Internet to Local Net.... In this rule is specified the ports which are listed in the GXP 2000 web browser on the advanced page > 1024-65535 <.

Now my Daughter is happy and still browsing. I have not had any random drop outs >> well not today....

Perhaps this might help other people resolve their Grandstream registration issues... The liquid crystal display on the GXP 2000 is worth considering... I can read it instantly without my glasses.

Post Script I will send this information to GRANDSTREAM... They responded immediately when I sent them an e-mail with very helpful comments.

Re drop out problems with voipfone accounts and Grandstream GXP 2000

1/ This problem was causing my company acute problems, with two accounts registered with VOIPFONE and my business relying on these accounts in the Slovak Republic.

2/ Chasing the problem by changing the parameters on the GXP 2000 web browser did not produce any tangible results in stability. The lines continued to drop out rapidly and on an irregular time pattern.

3/ Contact with Grandstream directly produced an almost immediate response from their technical department. Benny Rozeki made useful and concise comments to me.

4/ I passed Grandstream details of 'support' in voipfone on 22/02/2007.

5/ My accounts continued to be erratically registering on the two accounts causing concern until the 7th March. Suddenly one account became stable.... The second account continued to drop out erratically until the 8th of March....

I had not changed a single parameter on the settings to these accounts for voipfone accounts for several days prior to the 7th March 2007.

I hope that the current stable situation will continue. The GRANDSTREAM GXP 2000 has such a super LCD display and easy to use one touch dialling for my wife..... Peace has now returned to the Skelton household. The GXP 2000 phone is no longer under threat of being dumped in the dustbin....

Anyone else noticed an improvement with their Grandstream phones lately ??? john@inslovakia.sk

John, When you contacted support you said Grandstream had given you beta firmware which fixed you problem.

If you'd like to post it here anybody else suffering you problems would benefit too.

Link to Grandstream FIRMWARE UP LOAD PAGE

#13
To Help anyone with UPLOADING the latest FIRMWARE for GRANDSTREAM GXP 2000 phones PLEASE CLICK ON THE LINK BELOW.

GRANDSTREAM also state that another FIRMWARE UPGRADE is currently in BETA TEST MODE.

When this is released to the general user (Like me a 59 year old bumbling amateur) I will post again OK

MEANWHILE I can recommend that this upgrade is worth installing on the GPX 2000 phone from Grandstream.


Hope that this link will help other users.
