Implementing QSIG with Call Manager and Legacy PBX
We are implementing a Legacy PBX with CM and Unity. We will have 2 PRI's to the PSTN and two PRI's with QSIG back to the legacy PBX. I know there is some fuctionality that may be lost, but I cannot find documentation that explains what will be lost. I know that CM 3.3 has added some QSIG support, but I have not seen 3.3 yet.
