There appears to be an issue with my 027 number that has just been ported to Vodafone - if you call it from any network other than Vodafone (landline or mobile), the voicemail prompt just says "That number is not listed. To login to your voicemail, please enter your number now."
If you call from a Vodafone mobile, it plays the greeting as per normal. Can anyone else confirm if they are having the same issue with an 027 number ported to Vodafone?
I've called Vodafone who are looking into it as well.
