CTI Enable causes 1 Ext in a 2 Ext hunt group to ring for 1 call then stops accepting incoming calls?

[bodgeup]

I posted this topic on the SPA9000 thread but not had any replies so am trying in this thread.

Plese follow this link to see my issue: -

Basically my hunt group goes wrong after enabling CTI enabled on the SPA9000 which then sets it on my 4 SPA502's.

Thanks
