[cisco-voip] PSTN E.164 call routing

[Tim Smith]

I'm not sure if I'm getting the point here! apologies!

Are you saying for your purposes you dont care if it is LD or Local?
When you say ship out the E164 number, how are you getting this? Are the
users dialling it?

If you use a line + device css you can achieve a very simple route plan.
You dont need to break it up into local / ld etc for anything other than
your own restriction requirements? Are these simple as well?
In a really simple approach you could use 1 route pattern per site.. 0.! or
9.!
Lower your T302 timer.. away you go.
Add blocking translations to the line to take care of class of service
stuff. i.e. blocking international for some users or whatever you require

Not saying make all calls LD. But you should be able to dial an E164 number
from anywhere, by prefixing your international access code? Does your telco
accept this?

 My personal preference is same as yours.. simplify as much as possible...
then on top of that I'm trying automate the process of adding / managing the
route plan - to reduce errors, speed up changes, and reduce risk of RSI for
myself!
I wrote a script to add route patterns in bulk... I use a CSV, edit it in
excel, then upload the route patterns to CCM.

In CCM 6 you can actually export CSV of translation patterns, edit the CSV
(and add all your own entries), and then upload them back in quite easily. I
would expect CUCM 7 to extend this and make the route plan even easier to
admin.

Until then but if your environment is large, and management complex,
then you can create scripts / apps to ease the burden.

Cheers,

Tim
