I am looking to see if anyone has ever worked with a Carrier that allows hookswitch transfers from a Non-PRI T1, NI2, with 2 Way DID trunks built. I have asked the carrier TDS/USLink (whom I used to work for) about this question and they are asking me to find some examples. I do recall in my past job with TDS/USLink a customer (real-estate office) had a MCI Non-Pri T1, NI2 and switched serviced to TDS/USLink and returned to MCI due to TDS/USL not being able to accomidate this feature. I do know that TDS/USL is operating on a DMS 500 platform.
