I am having a problem with incoming calls, here is the scenario I am using a Grandstream 4108 connected to 8 analog Verizon lines in a hunt group, to a Win2k3 server with 3CX. If the receptionist is on the phone, and a second call comes in, it comes on the same line the current call is on (sort of like call waiting) (Linksys SPA525G+SPA500S) If the receptionist transfers an incoming call to someone, and another call comes in, if goes to the receptionist phone (working correctly) Here is the major issue; If an employee makes an outbound call from their desk phone, and a call comes in(which should ring at the reception desk), it just rings endlessly, receptionist phone doesnt ring, it doesnt try to beep in like call waiting on the user who is on the phone, and voice mail never answers it. Does this sound like a problem with my setup? Im also concerned that Verizon has call waiting on our first line even though their records do not show it and that is causing the issue? Thoughts? Thanks in advance for anyone who reads this with or without an answer!
