For your meristem to look 'woody' your plant is most likely in excess of 10 years old. I have a 21 year old climbing 'painted lady' philo that has those meristems. I can see that your stems are curling around in the container.
You can do one of 2 things. You can take top cuttings and root those. Once the stem is cut, what remains on the 'bottom' will sprout new growth. You could probably take your top cuttings, then cut back an even further section of bare stem, section that into pieces, plant them and get even more plants. Probably not all would root and grow but some would.
The second thing you can do is air layer the trunks and once you have roots on the air layer, cut that off and simply replant in a new container. The bottom left will still grow.
Or you can do none of that and just repot into a larger container.
