Ask them if they're replaced their router recently? If so, see if it's got a broken SIP ALG... (Some Draytek, Cisco, Zyxel for example) Get them to remove all port-forwarding on their firewall, remove all fancy port/ip address settings on their phone and use a STUN server. If they are using STUN, make sure it's working.
