onestopit Posted September 16, 2009 Report Share Posted September 16, 2009 We're trying to configure a Gradwell Enterprise SIP Trunk with PBXnSIP and getting '403 Method not supported' - which we also get on a standard X-lite client when we've tried it. I've been told by Gradwell support that this service doesn't require a username/password and authenticates by permitted IP address. How do I configure PBXnSIP Trunks to support this configuration?
