Hi,
i just wondered, if the "s="-line has to have content according to the standard?
The standard is not really clear about this:
Session Name
s=<session name>
The "s=" field is the session name. There must be one and only one
"s=" field per session description, and it must contain ISO 10646
characters (but see also the `charset' attribute below).
(Page 9 of RFC2327)
I've noticed, that my AVM FritzBox will tear the call down, if the
s=line is empty (other devices seem to accept that).
After putting a simple string "call" into the s-line, everything works
fine (changed the SDPFilter.cpp of the SBC-module)
Can anyone confirm, if the s-line must have content to the standard?
yes, it is needed.
have a look at the more current
http://tools.ietf.org/html/rfc4566#section-5.3
or
http://tools.ietf.org/html/rfc4566#section-9

Kind regards,
Carsten
