Calling Name and Number Feature
Calling Name delivery and presentation features are not supported by the Inter-Tel Key System for PRI link.
When calling from Cisco 7960 IP phone to Inter-Tel digital phone, Calling/Called Number is displayed on both phones after the call is answered as expected.
When calling from Inter-Tel digital phone to Cisco 7960 IP phone, IP phone displays Connected Number after the call is answered. Inter-Tel phone however does NOT get updated when the call is answered. It displays the numbers being dialed instead. (i.e. Access Code, extension number). It was verified using ISDN protocol analyzer that the CallManager was not sending "Connected Number" information in the connect message back to Inter-Tel Key System.

Test Configuration
Figure 2
Test Topology
The above diagram is representative of the various configurations used for testing.
As shown in the diagram above, an Inter-Tel Axxess 256 Key System was connected via an ISDN T1 PRI link to a Cisco 6608-T1 Gateway, which in turn, was connected to an Ethernet switch. The interoperability testing involved Layers 1, 2 and 3 on the ISDN PRI link between a Cisco 6608-T1 and the Key System.
Layer 1 (Physical Layer)
The Inter-Tel configuration screen for the T1 PRI trunk's physical layer parameters are under System ->Cabinets -> T1 Primary Rate Interface screen.
Layers 2 & 3 (Q.921 and Q.931)
Layer 2 and 3 packet exchanges were monitored using an Acacia Clarinet protocol analyzer, bridged across the PRI link in high impedance mode.
Layer 2 Q.921 packets were monitored to ensure that each Inter-Tel/6608 software configuration properly exchanged SABME/UA packets to initialize the ISDN link, and then RR packets were exchanged every 30 seconds.
Layer 3 Q.931 packets were monitored to ensure that the appropriate call setup/teardown packets were exchanged for each configuration, and that the SETUP packets contained the mandatory Information Elements with the necessary details, as well as optional IEs such as Calling Name and Number.
Telephone calls were made end-to-end in both directions through the Cisco 6608-T1 Gateway, and a check was made to ensure that there was an audio path in both directions for each call.
User/Network Settings
The Cisco 6608-T1 Gateway with ISDN protocol type setting of PRI-NI2 supports both protocol sides by selecting "Network/User" in the protocol side field when configuring the Gateway via CallManager.
The Inter-Tel T1 PRI, when set to NI2, supports "USER" protocol side only. Therefore Cisco 6608-T1 should be configured as Network side.
