Hi all,

Currently working from home and I have been given a VOIP phone but for some reason once a day, around the same sort of time the phone crashes requiring me to be pull the power and restart it, now I am not the only one this happens to, most of us get it at different times of day.

I have tried adjusting a few setting my end, I have forwarded UDP port and TCP ports 50, 51 although my router already has IPSec pass through enabled, I also changed my DHCP lease renew period, still getting same issue, only with phone as PC stays online.
 
No IT support from whoever issued you with the phone?

As someone that has to occasionally deal with end users it's the well intentioned people that try to fix things for themselves who are the biggest problem.

You haven't even mentioned then model of phone or any configuration details.
 
Let your IT sort it out. If the VPN is dropping then they should be able to check the logs and work out why, collect syslog from the handset itself etc.

If the phone hard crashes and becomes unresponsive then lol that's some garbage equipment.
 
Sorry should have said, The changes i did were what my IT department advised me too do, Now they have no other idea's.
 
That's not really acceptable though. "Hi home worker, we can't make your phone work, welp".

Surely their next step could be having you run a VoIP app on your mobile phone, or giving you a cheap Cisco ASA5505 to tunnel back to the office and plug your phone into, or installing a dedicated ADSL line that is connected back into their WAN so you don't need to VPN etc etc.

There's loads of options they can explore.
 
It's not something I've looked into that much with VPN & VOIP, but seeing as this happens at around the same time each day could this be a DHCP lease issue with renewing?

Not at user end as I tried that, it seems to do it 8 hours after switching it on, the same for the others it happens to.
 
VPN profile doesn't have an idle timeout or access hours policy? I would have hoped your IT would have checked their ASA (if thats what they use) for this when they said they ran out of ideas though.
 
If it breaks bang on 8 hours it sounds like each end of the tunnel disagrees on key lifetime.

But if that causes the phone to crash and need a hard reset then just lmao.
