 Number Portability (NP) is defined as a right for the Irish user by Comreg; however, while porting a number between Mobile Phone Operators takes less than an hour, porting an eircom fixed line number can take days to months even if GLUMP is not involved.GLUMP is not required to port an existing number to a non-eircom connection, such as VOIP or phone service provided via fibre, cable or Metro Microwave.GLUMP was developed in 2006.
