Description:Problem: When proxy requests digest challenge (SIP) Asterisk responds normally with the exception that for some reason it changes the FROM: (Also changes Contact: )to what's in the original TO: line. Why on earth is it doing this?! It must be a bug, I've gone over my extensions.conf several times to no avail. It seems older vers of ast don't do this.

near end is error:

****** ADDITIONAL INFORMATION ******

The only reason this is considered major is because our SIP handoff provider uses callerid as one of it's identifiers for billing, not only that if you were to dial a sprint phone for example and the users phone didn't have a password set you'd get right into their voicemail ;)

First find in the RFC what it says about this. It maybe wrong or a config issue.

Also NOT MAJOR.

Please attach the full sip debug of the transaction as an attachment ending in .txt, not just a snippit, pointing out which portion you believe to be in error.  Thanks!

I marked the first from line in the txt file, I upgraded to latest CVS and still found the same issue. Ty :-)
By: Mark Spencer (markster) 2005-02-02 12:36:23.000-0600

I think I see the issue.  Please try latest CVS and confirm that fixes your problem.  Thanks!
By: Mark Spencer (markster) 2005-02-02 23:41:35.000-0600

Assuming fixed, please feel free to reopen if you continue to have trouble.  Thanks.

Sorry for delay, I tried it again and this time I'm getting forbidden (challenge fail). I doublechecked the passphrases, not only that, nothing has changed on any one of the configs :-)
By: sirs69 (sirs69) 2005-02-03 07:06:01.000-0600

Ok, weird I tried it again and it worked.. Must have been a fluke.. ??
By: nick (nick) 2005-02-03 13:59:17.000-0600

OK, looks like this works. Reclosing.
