Hi, V11 Sp1, SPM installed at remote site, Grandstream 1450. MyPhone works from the remote site, but the phone doesn't seem to pick up it's provisioning configuration. Provisioning is working correctly for local extensions. I am attempting to provision remote extensions, following this: http://www.3cx.com/blog/docs/provisioning-a-remote-extension/ I don't see where I've missed a step. From the remote site /MyPhone works fine, but the phone doesn't seem to pick up it's provisioning at http://<publicIP>:5000/provisioning (with or without a trailing slash) Accessing http://<publicIP>:5000/provisioning from a web browser results in 403 - Forbidden. "you do not have permission to view this directory or page using the credentials that you supplied.". But that might be normal - problem is I cannot see whether the Grandstream is seeing the same thing. Could this be an IIS restriction, or where should I be looking to resolve it? Thanks, Les.
