[OpenSIPS-Users] B2b topo hiding transfer problem!

[Jorge Henrique Pinho]

Hi all, I am using opensips with module b2b with topology hiding and i having a problem when transfering a call, the b2b module does not forward the refer. The scenario that i am trying to achieve is like this one --> http://www.vocal.com/wp-content/uploads/2012/05/sip_transfer_fig2.gif, but b2b does not forward the reply.
Is this a common issue with this transfer scenario?

Kind regards
