I have an Audiocodes MP-114 gateway. My issue is when you call it, first it takes 2 rings to answer. When it does answer the phone it gives you a dial tone, after the dial tone sits for about 5 seconds it will go quiet for about another 2 THEN it will forward the phone call to the proper extension. Outbound calls don't have an issue at all. The only other issue I'm aware of currently is when you recieve a call, put it on hold, then try to transfer it, another extension, or voicemail it will hang up on the call. Thanks for the help.
