Ringing cadence on ring group members

[Dogbreath]

Set up new IVR for a customer, each option going to a different ring group. All works fine but the customer complains that the ringing cadence for calls coming through the IVR is 'internal'. [Don't know if this is a UK thing, but normally external calls go 'ring ring, ring ring' and internal calls go 'riiiiiiing, riiiiing']. I see you can set a CoS on a ring group and I have looked at the CoS options form but all I can see about ring cadence is for faxes and analogue lines.

Hmmmmm...my first thought is that since the call has been answered it is being transferred by the IVR so is an internal call.

Yes, that's how it appears to behave. A DDI pointed to the ring group rings with external cadence.
