MCIS 5.0 and PRI..... inbound callers do not hear ring back

[keebler224]

Hello all! I was in the hopes that maybe someone has run across this in their travels and would be willing to part with the solution.....

I have a customer that is running MCIS 5.0 and recently turned up a PRI with the Telco. All calls into the PRI complete, but the caller never hears ringing.

I am configured for NI2 and the telco is configured for NI2.

Is there a setting I am missing for providing this??

Any information would be greatly helpful!

That is a known issue with 5.0 the following is from
SRN-022

Enhancements made over MICS 5.0 WI 6.00

No Ringback tone on inbound calls
Customers calling into the Norstar system from the public network on PRI trunks will not get ringback tone from the Norstar. Those installs using the private networking or MCDN functionality will not be affected. The lack of ringback tone will be encountered when using any of the following protocols:
• NI2
• DMS 100
• DMS 250
• 4ESS
Customer installations using PRI connections directly to the central office will be the only sites affected by this issue. For those sites utilizing PRI trunking in M1 private networked environments installations will be unaffected. Customers using analog only installations will also be unaffected.

This has been addressed in MICS 5.0 WI 6.02

All MICS with PRI need 6.1 sw, rls 3 or higher to resolve known PRI issues. Don't even bother doing anymore trouble shooting.
