I see.
Ok but you somehow need those user/passwords to authenticate.
It’s simple, add those users/pass to the dB table in kamailio.  
You configure /etc/kamailio/kamctlrc for your db, then to create the database you 
execute:

kamdbctl create

You end up with the kamailio database, and insert your records in the “subscriber” table. Then configure usrloc to get the users’ authentication info from that table.

Hope that helps!

Thanks David. 

The asterisk PBX is being shut down as it is hosted with a different provider and I am wanting to bring the PBX in-house. Once migrated the asterisk PBX will be gone/deleted.

I don't have access to any of the Asterisk backend, which is why I am moving to a different solution. The reason for wanting to stay with the same username is testing. If I could just change the dns record for the SIP server, then the phones will automatically connect to the new system and if there are any issues, I can just switch the dns record back.

Is the users data asterisk uses in a db? If so, you can use the usrloc module to actually get the authentication info from that dB table. Check it out.

Hi

I am new to Kamailio and would like some guidance on linking up with Freeswitch. 

I have an exiting hosted Asterisk PBX that uses a combination of extension and pbx username (eg 1001-126252581276) and I want to move it over to Kamailio/Freeswitch without re-configuring the SIP phones.

I have tried Freeswitch "number-alias" but it does not seem like a good fit due to things like BLF not working and the added overhead etc.

Is there a way to configure Kamailio to authenticate a user based on the above username and then send an extension to Freeswitch as the UserID instead, thereby separating the Kamailio authentication from the Freeswitch UserID?

As I don't yet have a full understanding of the Kamailio/Freeswitch interaction, I don't know whether this will cause other issues? 

Thanks in advance
Petarr
