Has anyone ran got a solution for getting CNAM to correctly display if the sending and receiving phones are accessing the PSTN with different providers?

Phone A dials B across PSTN. If A&B are on same providers network, CNAM is displayed. If they are different, just the city is displayed.

This issue could very well be because of TELCO.

What I would suggest is when phone A call phone B over PSTN serviced by 2 different TELCO, make sure you are sending the proper info to your provider.

If you are sending the proper info but the called person sees the City name, its likely because the providers are not exchanging that info but overwriting it with something generic.

So, make sure you are sending the proper info and then involve your provider to troubleshoot further.
