Registration and making calls are two different things, you do not necessarily need to be registered to make outgoing calls.
Under "sip-ua", configure username/password/realm, and the router should use them in the authentication phase for each ITSP.

Ok, it seems to me that the current IOS is severely limited in this area:
1st, in "sip-ua" you can configure multiple (up to 5) password/realm combinations, but a single username. That means, if can have different ITSP to assign you the same authentication username, you can use multiple ITSP.
2nd, the authentication configuration in "dial-peer" mode, is available only for pots dial-peer, not voip. This appears like a bug in my opinion, or I would be very curious to know the reason why.
The above is actually documented at:

I've tried the configuration in sip-ua mode, as long the username is the same, you can actually configure multiple password/realm combinations. One final comment, the output from CLI on succesful configuration like Updating password for realm: xxx is really non-standard in IOS.
Hope this helps, if so, rate this post.

Hi ,
you tasks that the problem may be resolved upgrading the CME , now is ver. 4.0 (C2801-SPSERVICESK9-M), Version 12.4(9)T1 .

No, this limitation is not version dependent. I have a feeling it may be corrected in a future because it so absurd, However I have no basis to support my thinking.
Hope this helps, if so please rate post!

that doesn't look like a bug, but is reasonable:
authentication aids billing and CAC on provider side. If you could use authentication on voip dial-peers then the ip-device in your network using this dial-peer could authenticate itself the same way as a gateway in question. but if it is an analog or tdm device, it cannot do that so we have authentication only under pots dial-peers.
