Examine the trace steps beginning with the second outgoing call. Common causes of Multilink
problems are:
• The remote node or ISP may not support Multilink.
Confirm that the remote node supports Multilink connections, and that the phone numbers

Secondary Number.
• If you have enabled BACP, there may be an incompatibility with the remote router's BACP.
