Hi,

I seem to be getting this recurring issue with NAT Traversal using SIP via the 2820 router.

Please note that SIP_ALG is OFF
I am using softphones which are traversing the NAT using STUN.

in firmware 3.3.0 and 3.3.1.2 I find that multiple softphones on the lan share the same external port on the router.

I dont seem to get this issue with firmware 3.2.1 though

I'm having this exact same problem.

Did you find a solution? I've tried using a variety of the latest firmwares but no solution yet.

Was 3.2.1 definately OK?

Can someone from Draytek please look into this!
