We have a user that travels frequently. This user currently is using extension 305 on his desk phone and softphone. However, we have an extra unused phone that this user would like to take on the road with them for when they're in hotels. The unused phone is currently using extension 301. Would it be possible to set the additional phone to extension 305, so both desk phones as well as the softphone will all receive calls within the rules for extension 305. Or is there a different way to accomplish this?
