CUBE or H323 Gateway Using FXO Ports

[Ahmad2233]

Dear Good day,

    I have a CUCM 11.5 new installation to replace my CME, and I want to use my CME router as a voice gateway, we have a legacy FXO ports coming from our PSTN (we will change to SIP Trunk in the next year). Please I want to know which type of gateway should I use, and what is the initial configuration to make the FXO ports work for us?

This is the current configurations on our CME router:

You can certainly do this, you will first need to decide which voip protocol you want to use so that CUCM can communicate with your GW, your options are in order of my preference (SIP, H323, MGCP). If you decide to use H323 then you just need to add the H323 GW to CUCM, apply proper CSS to allow inbound calling, and build Route Group, Route List, Route Patterns for outbound calls.  If you decide to use SIP, you would add SIP trunk in CUCM that points to this router and again build RG, RL, RPs.  In both cases you will need to also add dial-peer(s) on the GW to communicate with CUCM.  If you do MGCP then you add the GW as the correct model under MGCP GW config and apply MGCP config to the GW.  

There are many guides and examples on how to configure each protocol, but if you have specific question on any of them, let us know.

Hi,

As @Chris Deren mentioned, you have three different options to configure your Voice Gateway. I would recommend to go with SIP Protocol as you will be eventually migrating to SIP Trunk. This will provide protocol consistency between CUCM to Voice Gateway and Voice Gateway to SIP Trunk (in future) and SIP Protocol is easier to troubleshoot than other protocols. 

Below is the initial configuration that you need on your Voice Gateway. On CUCM side, you need Partition, CSS, Router Group, Route List, Route Pattern, and SIP Trunk etc..

Thanks a lot, this is very helpful, and I'm going with SIP as you mentioned.
