I have two SPA504G voip phones and one Gigaset C530 connected to my UCM6202. I have four voip trunks and four inbound routes, one for each trunk.
Three of the inbound routes have a destination set to an IVR with time conditions. One inbound route has a destination set to a ring group.
The three inbound routes that go to IVR and ultimately to extensions via ring groups all work beautifully. The calls can be answered at the extension, and even can be forwarded to a cell phone through follow me.
The one inbound route that goes to a ring group is the one I’m having trouble with. When I attempt to answer those calls on the SPA504G I can hear the caller but they can’t hear me. However, if I answer those calls on the C530 it works just fine.
What is the problem with answering on the SPA504G on the inbound route that goes directly to a ring group? Again, on the SPA504G I can answer calls just fine on the other three inbound routes that start with an IVR, just not the route that goes directly to a ring group.
