Cause
The call cannot be completed because the equipment sending this cause value only supports the restricted version of the requested bearer capability, and in the SETUP message the bearer capability is unrestricted.
Communication Manager does not originate Cause value 70.
Proposed Solution
Procedure
Check Communication Manager administration for the cause value generated by the network.
- Route pattern: An incorrect ITC or BCIE or both. These fields affect bearer capability encoding in the SETUP message.
- The ITC administered on the originating endpoint is incorrect for this call, or the speed options for calls over these ISDN facilities in the device itself are incorrect or both.
- Incorrect data speed option set in the BRI device causes a call from a BRI endpoint sequencing through Communication Manager to create a SETUP message with the wrong bearer capability.
- A call sequencing through Communication Manager ISDN trunk group to ISDN trunk group has a bearer capability that is not supported by the outgoing ISDN facilities or network.
- A call sequencing through Communication Manager on a non-ISDN trunk group transferred to an ISDN trunk group has an incorrect bearer capability assigned on the incoming trunk group. The BC and ITC fields on the incoming trunk group are administered incorrectly.
