Is it possible to output SIP and PRI for same numbers over adtran Total Access 900e? We are a FTTH provider and we need to be able to do this temporarily for one of our business customers. The customer will have two PBX's in place for a while so once the call gets to both they will take care of the rest of the call treatment.
Simultaneously, I don't think so. Sequentially, you may be able to do this with a cost value in the voice grouped-trunk. If SIP has a lower cost and call is rejected it would try PRI and vice/versa.
