Hi there,


I'm brand new to the voice world and I"m getting ready to install a 2851 voice bundle in my office. I'm working on configuring the 2851 right now, and I have a few questions about the PRI configuration and setting up translations for inbound/outbound calls.


First, here is what I have for my PRI config:


card type t1 0 0

isdn switch-type primary-ni


controller T1 0/0/0

cablelength long 0db (default command)

pri-group timeslots 1-24


int Serial0/0/0:23

no ip address

encapsulation hdlc

isdn switch-type primary-ni

isdn incoming-voice voice

no cdp enable


voice-port 0/0/0:23

echo-cancel coverage 24

local-alerting

station-id name IT Team

station-id number 6270


Does that look correct?


I received the config from our current provider and have pretty much copied it exactly. The main difference is that the config I received has "pri-group timeslots 1-24 service mgcp" What's the function of adding 'service' at the end?


For the inbound/outbound call mapping, I have a small range of DID's that will map to the various extensions internally. How do I go about mapping those numbers? I've read some other posts, but I'm not clear on what the setup is.


Thanks in advance,


Brandon

No commands under voice-port are necessary.


You will need to configure one or more pots dial-per depending on the intended level of control. A compelte config has even more commands, translation rules etc but you can add these later.


Configure netwock-clock-select for the T1 also.


mgcp doesn't relate to CME at all, just forget about it.

Thanks for the quick response.


When you say 'configure one or more pots dial-peer depending on the intended level of control,' what type of control are we talking about here? and what's the difference between a pots dial peer and a translation rule?

Dial-peer is what decides where and how goes the call you dial.


translation rules are to manipulate numbers, often necessary.


You have to read a bit on some cisco voip primer, cme admin guide, at some point things will become clear (almost).
