You can buy phones that amplify the earpiece sound, so that you can hear the caller more easily. And for other phones, it may be possible to use a separate small amplifier that either attaches to the earpiece of the handset, or fits between the base and handset on a modern corded phone. Note that this works only on phones that have the dialling pad on the base unit and not within the handset itself. You may find some phones marked ‘hearing aid compatible’- this means that they should be usable with a hearing aid set to 'T' . Some phones also have built-in flashing lights to attract your attention when they ring, although this may only be effective if you are looking in that general direction already.
The information above applies particularly to corded phones, which are nearly always ‘analogue’. Cordless (DECT) phones, however, are digital and can cause interference with some hearing aids, although this is less likely if you have a modern digital aid. Some DECT phones are able to send and receive SMS text messages, which could be a useful feature for some – see Mobile phones.

Some phones may work better for you than others - so if you can, do try before buying.
