Ive been trying to get a couple of 7970Gs connected to a remote SIP server, but they continually fail to register. Same wires/switches work fine with my 7960s and 7961s (so I know the routing and NAT is fine). Is there anything special on the 7970G configs that I have to watch out for when it comes to registration? Ive tried a bunch of different firmwares (latest 9.x, 8.3, 8.5(2)) and now back to 8.5(4))

Hi,

Could I please get your files, from your TFTP dir. I have been strugggeling with the 7970 for days now. I do not know if the fimrware I am using is good or not.

thanks,
Roger
