IP phones

[michelvdriel]

Good Morning,

I'm posting in English as my German isn't sufficient .

I'm looking for some help with a Lancom 1781VA.

We have connected some IP phones to this device. I've tried setting up the firewall and have now even turned it off completely (not ideal, but to test), but I still have phone calls cut off at around 10 minutes into the call. I can see some blocked traffic, but can't figure out why this is blocked.

I have turned on SIP ALG to no effect.

Any help would be very much appreciated!

Hey michelvdriel,

disable SIP-ALG and increase your udp aging timer (set /Setup/IP-Router/1-N-NAT/UDP-Aging-Seconds 900)

Thanks! Just made the changes and will now have to look if this solves anything.
Will report back.
