[SIPForum-discussion] Valid SIP username

[Tomasz Zieleniewski]

Hi,

Assuming that You mean a user part in the SIP URI, from RFC 3261 it can be
any string containing
alpha numeric characters plus special ones:

"-" / "_" / "." / "!" / "~" / "*" / "'" / "(" / ")" / "&" / "=" / "+"
/ "$" / "," / ";" / "?" / "/"

there can be also the password element attached at the end prefixed with ":"
for instance some_user_name:password.

You can find more detailts in Augmented BNF for SIP from RFC3261.

Kind regards,
- Tomasz Zieleniewski
