Valcom Paging with Grandstream Device


If you are setting up a Grandstream with a Valcom paging system, be sure to set the Grandstram up as an FXO. The Valcom is an FXS and you cannot connect an FXS to an FXS.

It took 5 calls to our VOIP provider and 6 calls to Valcom to get that answer along with a lot of Googling. Save yourself the time.
