We would like to configure Quintum Tenor A800 to talk with Cisco ATA VoIP Box.
Cisco Box is configured and connected phone instrumet directly.
I have configured the Quintum Box’s sroute with Cisco IP.
From the Cisco Box I am able to dial Quintum.
But if I dial from Quintum to Cisco box it is giving engage tone (I dont want to dial PSTN line).
Please advice on this issue.
