[OpenSER-Users] Preserving original number when using alias_db_lookup

[Stagg Shelton]

Also,  the other reason why I want to do this is because I have many  
hundreds of DIDs that are assigned to many asterisk PBX's.  I am  
thinking that having asterisk register to OpenSER and then have the  
DIDs as aliases to the registration credentials would be easy because  
it's all contained in the database.

I'm so new with OpenSER that I don't know what the best way is, and I  
don't want to bombard the list with all of my newbie questions. I'm  
just trying to learn how to make it work, and then will come around  
and refine what i've learned along the way.

Thanks
