Very strange IPO 500 w/ SBC issue

Very strange IPO 500 w/ SBC issue

Hi All,
I am having a very odd issue with one of my customers IP Office 500's which has an Avaya SBC attached
IP Office is V11.0.0.2 and SBC is V7.2.2
The issue is intermittent however when it does occur it causes major problems,
The calls coming through (via sip trunk) sometimes show the same number/call in system status as if the person has called in from the same phone 5 times at the same time, once the call is answered eventually it clears down however this is a bit of an inconvenience as it steals all the voicemail ports for the time.
Set up is as follows Gamma SIP Trunks -> Draytek 2860 -> Avaya SBC 7.2.2 -> Avaya IPO V11.0.0.2 w/ VM Pro of same level.
Hopefully someone can shed some light, I have raised ticket with Avaya also,
Please see attached image
