User name as am email address

[Achraf Ben Hammouda]

Hi,
The Contact name consedered by our sip server is the email address.
When I specify my mail address as "Username" on pidging account we can't have connection with our sip server, because mail address contain "@" character and pidgin will consider "@" as a separator for contact name and server name
 ===> wrong contact name and wrong server.

Are there any possibility to accept user name as an email address.

Thanks.
