It's easy to set calling/called party number type for calls going out
local gateway, however , I just wanted to confirm how it actually works
in case of backup gateway and teho
Backup GW: Local call goes out HQ gateway calling/called number type set
to "subscriber", if HQ GW goes down, the local call reroute via BR1 GW
so in this case it's a long distance call from the perspective of BR1 GW
so called/called party number type should be set to "national" right?
TEHO: If HQ user dial BR1 pstn number it should route via BR1 GW first,
now in this instance calling/called party type is "subscriber" from the
BR1 GW perspective, but "national" from the perspective of HQ user
dialing..so not sure which one is correct??
I guess what I am getting at is when setting calling/called party
number type, do we look at from the perspective of user initiating the
call or from the perspective of the existing GW?
I think it would be based on existing GW....

Thanks Michael,
I totally agree about asking the proctor, and so far they have been very
helpful whenever I had to ask them anything.
I checked the SRND again and found the following.
Page 10-17
Gateway Calling Party Number Localization
+1415.XXXXXXX, strip pre-dot, numbering type: subscriber
+1.!. strip pre-dot, numbering type: national
IPExpert Lab 5 also shows that when a call is made to an international
number that the calling number type should be set to international.
This seems to indicate that the the calling number type coincide with
the called number type.
Can anyone confirm this?
Thanks,
cd

hmmm. I never cared enough to ask. I always ask what the carrier wants
(or get it off the paperwork) or just don't worry about it until
callerID is not showing up somewhere. Some don't seem to care what
anything is set to. Some need a specific type and plan in order to
display your calling number on the destination device. Then there is
the crazy reality of your calling number shows up properly on one
provider's network and doesn't show up on another provider's network.
Then there's AT&T. humph.
I would think if you set it to subscriber and your call ends up going
international, the carrier would (might) modify it.
Couldn't find anything on Google, so ask your carrier.
If this is a test question, I would think they would tell you what they
expect or ask the proctor. I'm guessing you were asking a real-life
based question. lol
Take care

Subject: [OSL | CCIE_Voice] Calling Party Number Type
Does anyone know of good information that details how the calling and
called number type should be set?
For called party I would expect it to be very straight forward:
US
7 or 10 digit dialing subscriber
11 digit national
011 International
Non-US (may vary)
8 digits - National
00 - International
Calling party number type on the other hand seems to be a bit more of a
mystery since it, at least in my mind, it is not dependent on the called
party (or is it?).
If I dial (US) a seven digit number (303-3333) that is understandably
marked as subscriber. But if I dial the same number as an 11
(1714-303-3333) digit number is it still marked as subscriber? There are
two variations, I dial 1714-303-3333 and send those digits out to the
PSTN, and secondly I strip off the 1714 before sending out the PSTN.
Should one or both be set to calling party type of subscriber?
So the calling party type scenarios are restated below for subscriber
calls:
A) 303-3333
B) 1714-303-3333
C) 1714-303-3333 (1714 stripped before sending to PSTN)
I will lump both international and national calling number type into
this question. How does the calling number type get set in this
situation? Should it be set to national in both cases? Or does it
change based on the number called?
Thank you,
cd
