Sure have. We (Monash) have four of them as we do exactly the
same as you propose on our two intercampus 2Mbps links. We pull
out 768k for the cisco-cisco links and leave the rest for voice,
etc. They have worked faultlessly from day one.

We heard of this too, however:

(a) it was T1 only, not G.703.
(b) it had not yet got certification for PABX attachment (a
lengthy and tricky process here.

 Haven't heard of anything.

BTW, the Integrator (the company is Scitec) can operate on 48V
DC, and thus sit in the PABX's power float.
