CVP using QSIG to a legacy PBX

[michael_oldham]

I wish to know if anyone has used CVP with a legacy switch where the connection between the PBX and CVP VXL router is QSIG and thus prevent call trombing or sometimes known as hairpinning after CVP transfers the callto an agent.

It will work no problem. As long as the voice gateway terminating the QSIG link is h.323.
