This is an issue with mobile subscribers roaming in another network(VPLMN) apart from their own network(HPLMN) :
 
Scenarios:
Location Update=OK
All outgoing Voice calls from Roamer=OK
All Terminating Voice calls to Roamer= Fails.
SMS=all OK

A trace is taken on the failing voice calls and the last MAP Operation is 'Provide Roaming Number'.

Can anyone assist on this please?

Heres a tracce:
