Hi,

We recently have a new SIP circuit from telco with 200 extenstions.

They had given me below details

Customer IP address=  192.168.1.224/30

STC IP Address =  192.168.1.233/30

Protocol= SIP 

SIP Port = 5060 

Transport Protocol=UDP

Voice Codec= G711 A-Law 

DTMF = IN-Band DTMF with RFC2833 

SIP Server IP address = 10.20.20.5

The Extensions range is
65291100 – 65291299

I have 2821 router and Call Manager 7.0

Kindly help me to configure it.

Thanks in Advance

Use this guide to configure your dialpeers on your router.


You will also need to add your gateway on cucm.

Thanks for reply,

Gateway was already added earlier as H323 gateway as we were using FXO ports. Do i need to make any changes to it.

Can we make sip trunk to Telco company on Call Manager.

And how can i translate telephone number to  Internal Extension.

And what dial peer should i be creating on router for call in and out.

I would appreciate if i can get a step by step guide to do this task.

Kindly advice.
