I am having a T1 installed that allows VOIP over TCP/IP communication from a remote office to Headquarters. My firewalls at each end do not have a CSU/DSU. How can I inexpensively terminate the T1 without spending alot of money on Cisco routers. I received a quote where the routers cost $1500 or so each.
My firewalls are Sonicwalls which do not have CSU/DSU's.
I thank you for your time and response.
