"NO NET FOUND" 3645 2

[liquidshokk]

I'm about to drop kick an AVPP and 4 3645 handsets out of the window in a minute...

...but before I do, does anyone know why I would be getting "NO NET FOUND" on a new installation of 3645 handsets, when SIP details for Wi-Fi provided by draytek router are correct and handsets and AVPP are on latest software??? The mac address of the router is displayed on the handset screen.

I've seen reference to a resolution of setting 1719 to be pointed at the IPO on the router, however this is already in place as we use remote phones, and besides the 3645 handsets are being used internally.

Someone save this poor equipment before it gets hurt

Thanks

They don't use SIP on the IPO, they use H.323 so 1720 is needed too.
I have struggled with these phones from hell too and i will never ever do it again.


BAZINGA!

I'm not insane, my mother had me tested!

 

[liquidshokk]

1720 is also pointing to IPO on our router. Surely this is irrelevant if not coming in from outside anyway?

This is meant to be replacement for DECT R3 to resolve all the issues they have had with that!!!

 

[tlpeter]

Seriously, replacing dect with wifi phones is a step back at all times.


BAZINGA!

I'm not insane, my mother had me tested!

 

[liquidshokk]

I was under the impression it would be an improvement. Would DECT R4 have been the better option or is there some other offering from Avaya I'm not aware of?

Not sure what I do with £3k of kit now...........

 

[tlpeter]

Dect is always better, specially with the roaming part.
With wifi phones i always hear the roaming and with dect i never heard it.
But both require good site surveys and i guess that was the issue with the old dect already.
What where the problems?


BAZINGA!

no net found is usually a authentication issue from phone to access point. double check the encryption and credentials on both handset and phone.

phone > ap > svp > ipo

You cant get past the first connection point. Also I don't recall being able to use spectra SIP firmware.

 

[liquidshokk]

Ignore the SIP bit, that was a typo

I set up another router (netgear) and connected to that straight away!!! Bloody Draytek!!!

 

[amriddle01]

We have seen numerous voice related issues with Draytek routers, shame as they're great value otherwise

 

[liquidshokk]

OK so replacing an Avaya DECT system with Avaya W-FI handsets has come back and bitten us on the butt as tlpeter said it would :I

Customer is reporting that voice cuts in and out and the phones occasionally drop off the network, reboot or turn themselves off!

We removed the AVPP as the IT maintainers informed us that their wireless AP's handle the QoS and that WMM mode is enabled. They don't have problems with wi-fi devices that are sat next to the wi-fi phones when they disconnect/have speech issues.

I'm guessing there isnt a lot I can tweak on the IP500 itself as they are essentially just IP extensions but are there any settings on the handsets that can be changed to try and make them more stable?

Thanks

Switch off the phone.

Starting point is to check the VIEW Certified AP Configuration Guide at

http://support.spectralink.com/products/wi-fi/view-certified-ap-configuration-guides

for whatever WLAN is deployed by the customer. The Avaya 3641/3645 are equivalent to the Spectralink 8020/8030 in terms of these guides.

 

[liquidshokk]

Already done that Okkie26, but thanks. Will double check the settings...

Thanks gwebster. I hope the IT dept take the time to read it and make amendments where necessary.

 

[Okkie26]

Is there a DHCP server available? Are you sure you enter the SSID correct ( case sensitive ) ?

 

[liquidshokk]

They do work, they just intermittently have issues with quality/drop outs. They are using an SSID that is solely for the wireless phones

 

[Okkie26]

AVPP address set in the IP Office?

 

[tlpeter]

Okkie, I have been dealing with these crappy phone and there isn't a setting to solve this.
The WiFi must be cover only or totally setup for voice with data at the lowest priority.
It is a crap solution.
Replacing dect with WiFi is a disaster waiting to happen.
I will never ever do it again.

There are a lot of things to consider when deploying VoIP over WiFi, I have tried it once and after six months of trouble and on site engineers from Avaya and Spectralink we removed the whole lot and installed IP DECT. What a relief! Worked from day 1.
I stay away as far as possible from VoIP over WiFi.

 

[nnaarrnn]

Wierd, I've never had any trouble with it.

I use the 3645 phones with Cisco 1042/1641 APs with Cisco 2504 wireless controllers quite a bit with no issue. I can walk every inch of a particular site (15,000 square feet, concrete walls) with zero packet loss or call quality issues.

Its all in the wireless network, mostly the roaming settings and overall signal level. If the signal level gets much worse than -75 dbm, expect the phone to disconnect/drop. Higher AP density with lower AP power seems to help, especially in areas with high numbers of WLAN clients. Everyone associated to that particular AP is fighting for the bandwidth that the radio can provide. If you're on 802.11b only, its worse as you're competing with other 11b/11g devices for that 11 MB of bandwidth, not to mention the rest of the electromagnetic soup that exists in the 2.4 GHz band. If 802.11a is available on the APs, you could try that as you have more channels to choose from, but you sacrifice range, and 5 GHz is attenuated more by obstacles than 2.4 GHz.

I've had installs where two phones worked like complete crap and I've had installs with well over 100 wireless phones where everything works fine.
