asterisk users - Jul 2010 - Aastra phones occasionally show "No Service" - Is there any network setting I can tamper to facilitate a quick DHCP renewal on the Aastra phones?

Hi Everyone,

I am running DD-WRT on a router that feeds about 30 Aastra 6753i. The phones
occasionally go into "No Service" mode. The POE switch doesn't
seem to be
the problem as it's tested fine. I think the router sometimes gives up and
comes back quickly. Or something of that nature. However, the connections
are maintained if a call is going on because there are peer to peer
connections between the phones in a network. Anyhow, if the phones are
restarted they work fine.

So, I was looking around the Aastra Admin UI to find any timer to lower it
to 1 second to check and make sure the device always has an ip but I can't
seem to find anything other than LLDP which is set at 30 and I don't think
that will be of any help.

I did a test where I would disconnect the router from the switch and after a
while phones go into "No Service" but if I plug it back into the
switch the
phones do not come back right away. Maybe something should be dialed on the
phone or wait long time or restart it to work again.

Any work around?

Thanks a lot

Try changing the registration period so that they perform a regular 
re-register. That way if something happens and they fail to register 
when they notice a problem they will try again a bit later.

try to have a dns cache into your LAN, Aastra phone are prone to fail when
have any little DNS error.

Adria,

How can I build a dns cache into my lan? I am using a Linksys 48 port POE
switch and running a micro DD-WRT firmware on a linksys router.

Gareth,

I think the registration time is part of the reason. I have lowered it less
than 10 seconds.

Thanks

DD-WRT supports DNSMasq which would do exactly what you need.

Hi Bruce,

 

Did you ever get a working solution and confirm the underlying issue ? I am
having the same issue on a set of phones, my next step is replacing the
router, but I was wondering if you found something else.

 

Regards,

 

Mike
