atcomsystems.ca/forum Forums Wiring - Telecom Carriers - Trunks & Services T1's, CSU's and DSU's PRI circuits via "Soft Switches"

The ones I've installed that are using the "soft switches" that are set to NI-2 I've had almost no problems. The ones where I've had to use other settings such as AT&T Custom (for Legend/Magix) I've had about 50% success. Some customers are happy as can be, others have had caller id issues, random lost calls (with no error reported), misc d-channel errors, you name it.
