Call Manager 6.1 SIP Trunking with Internet telephony service provider

Hi

We are having a site coming up which requires integration with a local Internet telephony service provider (ITSP), which supports SIP integration.

The service provider will be providing the IP Address for the service and login credentials for the SIP Service.

What are the components and configuration required on the Call Manager side.

Thanks.

Hello,

All you will need is a router/gateway that has an IOS that supports CUBE. I believe the way it is configured now is SIP trunk to ITSP and then SIP trunk between CUCM and the CUBE. This doc shows basic configuration:

Hope that helped, if so please rate.

Thank you for the info.

We will be using Cisco 3845 SRST router for this site which will connect to the CUCM cluster. Can the single Cisco 3845 route support SRST as well as CUBE features?

Re: Call Manager 6.1 SIP Trunking with Internet telephony servic

Yes it should, just be sure you are using the proper IOS image to support these features.

Would this also require licenses for SIP Trunk or CUBE calls?

Re: Call Manager 6.1 SIP Trunking with Internet telephony servic

I dont think you need licenses for CUBE or SIP trunk, just for SRST.

Last question, the login credentials provided by the SIP Service Provider will be configured on the router in the SIP User Agent Configuration portion?

Re: Call Manager 6.1 SIP Trunking with Internet telephony servic

Actually, this isn't quite true.
