First of all, I wouldn't recommend running your OBi202 in DMZ mode...
Sounds like you have a firewall issue, what make model routers are you using?
Also, have you disabled 'SIP ALG' on your routers? Have you forwarded any ports? If so what ports?
I'm going by memory here, all you need set on the Cisco SPA525G2 is the following:
EXT 1/Proxy = obitalkphonenumber.pnn.obihai.com:5063
EXT 1/User ID = 1001
EXT 1/Password = Password
EXT 1/Register Expires = 60
EXT 1/Register = yes
SIP/Send Resp To Src Port = yes
Can you confirm you have the Cisco SPA525G2 configured this way?
The setup on the OBi is a bit more complex (we won't go there just yet), and you need to specify a call route on the OBi202, have you done this?
Appreciate my support? Feel free to buy me a beer!
