Hey Ron,
I use the 2820n router as well, with a few IP phones, some on Public and some on Private IPs. The Vigor's SIP ALG is ON, STUN is OFF on all the phones, and its' QoS is set to prioritize VoIP packets in both directions.
The last time I used the Nokia SIP stack was a couple of months ago, when I was setting up the built-in client on an N97 mini. It took me a long time to finally get it to work, and it was not very reliable to operate.
Based on my experience, the Nokia SIP client is not to be used on a daily basis, as a main extension to deliver calls consistently. There are other SIP clients for Symbian which you can use to mitigate some of its' issues. One you might try is the Media5-fone from a company that provides support even on their free version.
It has been my overall experience, that dual mode handsets (WiFi with SIP / GSM or UMTS) are not fit for active duty like desktop IP phones or ATAs are. They are more fit for infrequent calls when you are out of the office close to a WiFi hotspot, or via a reliable 3G data plan. That's it.
For home or office use, I would suggest using a DECT IP phone like the Gigaset A580 IP which enables you to move around. The DECT wireless interface is optimized for phone use only, whereas the WiFi interface is optimized for PC data transfer and thus designed not to turn off its' radio. WiFi performance is finicky on almost all dual mode handsets, and this has detrimental effects on voice quality, let alone their battery life.
To make a long story short, I wouldn't stop using the 2820n with its' advanced capabilities, and replace it with a simplistic DLink router, just to allow the Nokia SIP stack to properly operate. I would either get another handset or try a different SIP app.
