Have a new hospitality customer in a remote area that is not cabled to handle IP phones. Only digital phones available are 4025s. We have programmed the ports typically used for the console and sub-console for the 4025 but display comes as no access when trying to make an outbound call. When calls come in on the trunks we are directing them to the 4025 (x290) it rings the set only 1 or 2 times and then VM box grabs the call even though no forwarding to VM is set. We have checked the interconnection table and COS/COR. We can only seem to dial extension to extension.Any ideas?
