    Will Grandstream phones work on other VoIP PBX systems besides the Grandstream system?

      Hi Robert! Thank you for asking your question. The short answer is “maybe.” Grandstream is a SIP based VoIP phone, so it is capable of working on other product lines, but they would need to be tested and approved by Grandstream for inter-operation. If you have any in mind, contact us and we are happy to discuss the specifics.
