Included the following line.
voice-port 2/0:D
bearer-cap Speech

The bearer-cap command will have affect outgoing calls from the router towards the ISDN.
For inwards calls from the ISDN towards the router, you need to add the D channel command 'isdn incoming-voice modem' to allow the router to recognise the inwards speech bearer capability.
interface serial 2/0:15
isdn incoming-voice modem

This did the trick:
interface Serial2/1:23
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice modem
no fair-queue
no cdp enable
Thank you very much for the reply.
