Hi, I could not Register phone (status = Registration failed),manual I.P is set & I could download and update latest firmware..etc. attach console images.
For more info., registration may not be possible because its block by internet service provider, any suggestions or methods to bypass with different setting so that registration is possible.
I am using ADSL internet router (no firewall).
Attach Image of registration failed and advance tab shows Sip & RTP ports
