hi

1)when networking two systems via SPNET,call it pabx A and pabx B, how should pabx B be programmed to dial out via pabx A for external callS

2)can a OS7100 ver 4.70 be networked via SPNET to a dcs500,is it the same procedure one would use for newer systems

YES you can dial out using lcr settings from another mode just done one .
you can spnet a 7100 to dcs500 you would need mgi card in dcs500

HI, could you please elaborate on the lcr settings
