The value of username comes from the username part
of To URI. What
probably confuses you that there is msn1-0003f5 in display name, this
is just an informative text used by user agents to display the name
of the person in human human readable way. It is optional.
hm, strange, so i send "to: 12345(a)mysip.de" with
Authorization: DIGEST username="msn1-12345678" and then
i am register with "12345" ?
serctl ul show 12345
200 OK
<sip:12345@127.0.0.1>;q=0.00;expires=3226
Should it not be a registration with username "msn1-12345678" ?
greets,
Markus
