DIDforSale SIP Trunk Architecture.
A brief architecture of the big picture will help you understand what role does Grandstream PBX play in your communication application?
Grandstream IP PBX (Private Branch Exchange) is one of the many IP communication solutions provided by Grandstream. When using Grandstream IP PBX the calls sent to you by your phone provider are forwarded to Grandstream IP PBX. From there the switch determines how to route those calls.
