Hello All,
Has anyone used external paging on the NEC Univerge Blue?
What Paging adaptor works well with legacy amplifiers?
What resources are you Purchasing for this?

Also, has anyone use an ATA on the cloud PBX? which one works? Which resources are purchased?

Any help would be appreciated.

Which version are you using? Are you completely hosted or do you have on premise phone system connected?

completely hosted..

Best would probably be an FXO or FXS with the proper paging interface. I have for some remote VOIP installations done custom RCA connector to an old VOIP phone off the speaker leads to the amp.

We've often used the Snom PA-1 to get a paging output from IP or Cloud systems.
