Hi there,
We have purchased and installed Allworx 10 pbx and use Grandstream 2000 phones in our office.
The external caller-id's do not show, although id of the calling extension (internal) shows up on the display.
Of course, mixed vendor environment, they both point to each other and you get no help :-)

Does anyone have experience with this kind of a situation, or has suggestions?
Thanks,
Derya
