[cisco-voip] Consequences of changing numbering plan type

[John Neiberger]

I'm trying to get QSIG working between CCM 4.1(3) and some Nortel
PBXs. In order to solve a couple of different problems, I had to
change some settings that Cisco recommends leaving at the default.

On the gateway configuration page, I changed "Calling party IE number
type unknown" to Subscriber (default is CallManager) and I changed
"Calling Numbering Plan" to Private (default is CallManager).

We have a centralized Meridian Mail system and these settings solved
some problems for us. However, I'll be honest and say that I don't
know exactly what these settings do and I haven't been able to
determine the details from reading the documentation. Are there any
possible future consequences I should be aware of?

Thanks!
John
