i have set up AAR on a CM 4.2(3) system. I realise it overflows to PSTN when bandwitch threshold has been reached. Problem is is doesn't send any extra digits. For example phone in site A calls site B extension 8111, when i do debug isnd q931 i see pstn call made but called party is only 8111 even though i have put prefix digits in AAR group. I think i must be missing something. Does someone have any ideas?
