Well here’s goes.
I have a UCM 6202 with a 4 xport Beronet ISDN converter on it.
We have no incoming cli on the trunks it just says anonymous,we also can’t pass DTMF signals through it so can’t have the IVR turned on.
The BLF keys on the 2170 handsets only work with the handset in the cradle but work fine on 1630 handsets.
On the incoming ring group you can record a greeting as a wav file and have it play to incoming callers ( again this doesn’t work ) if I call the group 510 internally it functions as it should but does not work for incoming calls.
Surely I can’t be the only dealer having these issues with this hardware, the site has 10 x handsets on it and between myself and the distributor we have spent over 13 hours on site and it still doesn’t work.
The margins are tight on this kit anyway and after spending so long trying to make a basic system work I’ve completely lost faith in the product.
Grand stream from what I have found have no real testing of the product it’s like as installers we are the Guinea pigs and every fault is greeted with oh we will pass it back to the manufacturer…!!
