Openser is a SIP proxy and thus were not made to handle this situations. 
But you could try the uac module. This module was written for this 
scenarios. but be aware, you might experience problems if the 
voipprovider uses a proxy which is very strict (CSeq problem between 
your SIP proxy and the voipprover SIP proxy).
