[sr-dev] Quotes in $pn and $fn

[Jasmin Schnatterbeck]

Hello list,

while using from/p-preferred-identity display names in kamailio.cfg I
noticed, that $pn and $fn contain the beginning and ending double quotes
("<display name>") supplied by the UAC.

As those quotes not part of the display name (at least I think so - e.g.
they are also not shown by end user devices) I suggest to remove them
from $pn and $fn, because otherwise you have to remove them manually
with pv transformations/substr, which may takes much more performance...

Best Regards
Jasmin
