Using an ATA 190 for paging, connecting to a BOGAN TAMB2, without using the timeout features on the TAMB2 unit, call will not disconnect.  Any suggestions?

ATA 190 Version 1.2.2(003)  CMCU System version: 12.5.1.12900-115. connected to CM without issue, can dial internal, external, and receive calls.  The unit will not provide any dial tone.
