Good Afternoon, I am managing a setup at work where by we have a Patton Device, as well as a GSM gateway. we have both a VOIP number with melita and 2 mobile numbers which we use for 24 hour support. I am all of a sudden seeing that when a call comes in it rings twice then diverts instantly to my work mobile. We also have diverts setup at the sim level through our mobile providers to form an external hunting line, and this protects us against any power outages as well as any internet down time as we will still get any phone calls to these numbers instantly diverted to our mobile devices. What do i have misconfigured where it only rings twice and then diverts. Any help would be greatly appreciated.
