[Serusers] Append prefix to RURI via AVP

[Martin Koenig]

Hello,

is it possible to add a prefix to the RURI that is based on an AVP, 
similar to prefix("x")?

Scenario is the following:

Each user would have an assotiated avp called cc and ac. Depending on 
incoming RURI, Ser would first add the area code avp, then the country 
code avp. Is this possible?

With best regards,
Martin Koenig
