[OpenSIPS-Users] How to add an IMPU as subscriber with username (sip:108 at example.com)?

[Cao Lei-MNW784]

Hi, Everyone!
 
I tried to add a new user using:
 
	opensipsctl add "sip:108 at example.com" 108108
 
However, in the database, the new entry is added as:
 
	| id  | username | domain          | password   | email_address
|
	| 42 | sip:108     | example.com | 108108      |
|

I want to use the full IMPU format "sip:108 at example.com" to do digest
authentication. But the username configured in database is "sip:108".
Any suggestion that how to add a subscriber so that it has username
"sip:108 at example.com"?
 
Thanks & Regards
Cao, Charles
