Hi, all: I just set up Elastix in my office, but during testing, I find all phones, when receive calls from our E1 line, the receiving phone can't hang up properly if the call is not being answered and the caller phone just hang up, The receiving phone will just keep ringing. But it works fine with normal PSTN or SIP-to-SIP. So I try to solve it, and find out when Signal RINGING is checked for inbound route. However, when I happily proceed to set up IVR, I find the problem begin to happen again. I know in the description of Signal RINGING, it may not work with IVR, but this problem is really annoying. Anyone can tell how to configure Elastix so Signal RINGING can work with IVR, or some other alternatives that can make receiving phone hang up properly?? Thx in advance!
