I have a KX-TD816-6 hooked to a TVS-90 attempting to do Call Forward to CO for an after hours answering service. First the call would hang on for about 10 seconds and then drop you back into the VPS. I changed the transfer to FXD and now it does just that, hookflash, dial and then disco but it discos from the line it grabbed to do the transfer and never transfers you. I've enabled the call forwarding in both systems, I've checked the Extension-CO and CO-CO timers. I've verified that if the extension forwarded is dialed that the forwarding completes. I've listened to the call go through with my butt set and can hear it dial, ring and then the VPS just drops the call without connecting. I have this working on two other systems with near duplicate config. Any assistance is greatly appreciated.
