Hello everyone,

Yesterday I decided to upgrade my asterisk-setup at home and install it
with Asterisk 15.4.0 which comes bundled with pjsip 2.7.2

Incoming registrations work just fine with most for most of my clients -
except a (admittedly quite old) Patton mATA.

For further investigation, I enabled to the debug-output and found the
following: https://pastebin.com/raw/nCssPuCm

As you can see, the device is sending the REGISTER and gets the 401
returned - but then nothing more happens.

It took me some time, but I then realized, that there are two whitespaces
in between "WWW-Authenticate: Digest" and "realm=".

I tried patching around a little bit and realized at some point, that those
two whitespaces seem to screw up the device. As soon as those two
whitespaces are just one whitespace, the mATA sends a new REGISTER with the
proper authentication.

Unfortunately, I was not able to locate the proper part of the pjsip-source
where this double whitespace is introduced - so I am writing this message,
hopeing that someone more knowledgeable can fix this.

I didn't report this bug to Asterisk as this seems (to me) like a
pjsip-bug. If this assessment is wrong, please let me know and I'll report
it somewhere else :-)

Best regards,
Martin

Re: [pjsip] "WWW-Authenticate"-line contains two whitespaces?  Hello Martin,

Attached the PJSIP patch which should fix this issue.

Nanang,
Could you, please, commit this patch.

Regards,
Alexei
