ISDN BRI with PBX

Dear All,

I'm unfamiliar and newbie to the VOIP system and need to setup small system for branch office.

I've just dug out a few related post from here (thank you netpro) and would like to ask a few question.

Here's the most similar example for my case.

please see the attach for sample diagram.

How can I configure for all international outgoing and incoming call ( with/without CUCM connection somewhere) in my router ?

Is it possible to configure all the call routing inside PBX ?

Please advise me how to set up in simplest way.

Thanks in advance

What is that you want to do in practice ?

If you're the endu user I recommend you locate a reputable cisco consulatant, because if you try this alone, you can semd a lot of time beforemaking it work 100% perfect.

Thank you bevila,

I'm not going to do it for practise.

I'm quite familiar with IP routing and switching but not with the Voice traffic.

I need to set this up with PABX vendor and i'm afraid some sort of issue will arise.

No issues as long the right equipment is used with the right configuration.

great, any kind help for the sample working configuration with international DID numbers ?

It really depends on what you are doing, internal calls usually are dialed 00[1-9]

let's say my telco assign 083 1234 500 to 083 1234 550 for my office.

How should I configure the dial peer for both outbound and inbound call ?

Are you placing the router between PSTN and PBX, or are you placing it on a separate PBX interface ?

In any case, begin with:

You need to at least learn the fundamentals before asking others for more help.

i'm placing it on separate PBX.

Can it be done if the router is only connected to PBX and IP network ?

there's no direct PSTN connection to PBX nor router.

grazie paolo

Yes, it can be done.

Again,please study a little when you have the router, what you want to do is not complicated but requires attention.
