Git it set up here, got to say find it pretty useless, Yes its speed calls only and I want DSS buttons on my handset.
Once set up I had to play around with Avatar sizes in Micollab and had several attempts to get them to display, If it doesnt work 1st time there is a button on the Phone under settings/advanced to update the avatars.
What I do find useful is the conference button I have programmed so my scheduled conferences come up with a reminder on the screen and give me 1 button access
