I have an Obi 100 and 202. I used them before about 2 yrs ago flawlessly to call between each other. Recently decided to start using them again. Both have green lights and could be added to ObiTalk again. BUT it shows them both off line and status unknown. I have the latest firmware. I reboot both devices. I deleted them from the Obitalk and added them again. I try to dial **9, 222222222 and get "There is no service available" on both devices. I put the 202 in the DMZ. Still the same.
Please help.
Thanks.
