T46S-Vonage Overwriting Remote Directory

[igendreau]

We have T46S phones with Vonage. I created an XML file that's on a local server. I set the Remote Phone Book to point to that XML file. Then, in the Directory Settings, I only have Remote Phone Book enabled. So everyone is pointing to the same directory, and I can easily edit it once, create nice little department groups, etc...

The problem is, every so often, something between Yealink and Vonage is overwriting that setting. I'll have a user complain after weeks or months that their directory is wrong. I'll go in, and sure enough, the Remote URL in Remote Phone Book is something starting with http://prov.vonage.com... etc...

What I'd like to know is, is there some combo of settings I can pick so that once I set the value on this field, it doesn't change? Vonage was pretty useless in helping with this, and claims there is nothing on their end that they can change to stop this.

The directory it changes to when it points to Vonage is correct and up to date. But it has no grouping, so it's a giant list of names. Much prefer my custom XML. Any thoughts are appreciated. Thanks!
