oh lol my fault. thats what i meant. now i did a firmware update of both devices vth15 and vto2000a. my vto2000a is connected via 2-wire. in my vth the device isnt listet and i cant add one. is there something that i forgot to configure?
btw thanks a lot
Another question. i was trying around with other firmwares. it seems like a downgrade isnt possible anymore, am i right?
EDIT No 2.:
i found newer firmware for 2-wire models and was succesful in updating them.
Is there a way running a SIP-Server on one of the devices AND let them work together via 2wire?
