The following high-level process
is recommended as a guide to
assist in determining the cause
of post-port call routing
issues.
Process
1. Customer ports number
2. Customer reports problem
making and/or receiving some
phone calls since porting to the
New Service Provider (NSP).
3. New Network Service
Provider (NNSP) checks to ensure
that the NPAC active
subscription version (SV) data
is correct.
4. NSP reports the problem to
the Telco that is routing calls
with incorrect LRN (SCP/STP is
discrepant with NPAC).
5. These issues are reported
to the Telco’s Network
Operations Center (NOC).
6. Both Telco’s work together
to identify and correct the
problem.
7. Telco will notify to the
reporting Telco when the problem
has been found and corrected.
8. NSP may notify the
customer that the problem has
been corrected.

troubleshooting in a multiple
service provider environment,

Environment.
