Babaganoosh...

If you read my dial strings and you actually have access to it in your ATA, insert the first two 123 as they appear in my Linksys plan..don't forget the | and spaces...stick them in at the beginning exactly as they are. This takes care of the VM wait time on the Grandstream.

I am using my SPA2102 now and since I don't use the system VM, I never noticed this. I just tried it in my Linksys with the Grandstream dial plan and all is well here.
