I recently migrated from Incredible PBX to the new PBX in a Flash 5 which runs on Debian and powered by 3cx at the core. Must say I am very happy with it so far. I have read that the same extension could be provisioned on multiple devices, is this true for the same extension to be registered at the same time though on multiple devices? I have 10 desk phones, each with separate extensions. On the old server I simply setup a symlink so that the extensions ended up sharing the same voicemail box, and this worked amazingly well. As soon as somebody left a voicemail message, all 10 phones lit up to show there was a voicemail message. On 3cx however, using this same practice seems to still only affect the 1 extension where the voicemail box is actually setup. How would one setup the same voicemail box for these 10 separate extensions? We like having separate extensions since a call may be transferred to another desk phone easily to move around the office and such. Any thoughts?
