Hello,

I have R26P and I try to configure it with iptel.org account, however always I get Registration Failed error.
Firmware Version 26.31.4.111
Hardware Version 26.1.0.0.0.0.0.0
SIP Account settings:
Register Name: sip:[email protected]
User name: [email protected]
Password: xxxxx
Server IP: iptel.org
Port: 5060
Transport Type: UDP
NAT Disabled

I try all possible combinations and always failed.

Hi
Your configure looks correct. Have you try this accout on other device? Or is that R26 network normal can search internet?

yes and it works smoothly, only r26 have problem with registering/renewing connection.
