Hi All, We are connecting a Businessphone 250 to a Cisco router using E&M. Outgoing calls work fine but inbound calls receive a fast busy tone. The BP250 is set as continuous format A and the router is E&M type V 4-wire immediate start. Apparently there are dipswitches on the BTU-E can anyone tell me what these are for or have any idea how I can cure this problem.

Hi Jaakie.
Do you have DTMF receiver (REG, MFU or VMU)?
You can do internal loop with 2 circuits in BTU-E and you can verify if your call is ok.
I suggest check the following commands.
1007 to 1012 and 1017 (YES).
1101 to 1104 to operator extension (200)
1023 (2)
1201 (9) Continuous E&M A-Format
1301 (DTMF)
1302 (DTMF)
1307 to 1309 (YES)
1609 (116) 4-W tie line BTU-E
1706 (YES)
1707 (YES)
1708 (NO)
1709 (YES)
1710 (YES)
1712 (NO)
1717 (YES)
1718 (NO)
The commands 18XX depend if you need add or truncate digits.
The wires are conected thus:
(a) - (a)
(b) - (b)
(E) - (M)
(M) - (E)
