Trying to find a way to save some money and improve service. We currently have a Axxess 8.2 with 6 POTS lines and a fax line. The cabinet has a LSC, IPRC but no T1 card. We're paying over $400 per month for the 7 lines.

A PRI would save a little money but provide way more lines then needed and we don't need the data. Would SIP trunks be a good way of going? If so can the Axxess use SIP trunks with some updates and or cards?

Thank you in advance for any ideas.
