CA_Close_CHP_Link() failed
A call to CA_Close_CHP_Link() failed. This means that the link to the CHP for the outbound part of a transfer operation cannot be closed. This may be caused if the outbound state table exits before the ISDN_Call_Transfer custom server has a chance to release the link. This should not happen if the outbound state table is working correctly.
If the problem persists, take an AIX system trace while re-creating the problem. Specify the -d command line parameter for the custom server. Then call Blueworx Support.
