Hi.
i have found two issues:
First is in EndpointRec::SetSocket(CallSignalSocket *socket) there is
if (!socket->IsConnected()) { return; }
which in (i think) some kind of race condition with tcp handshake
sequence causes first information packet sent in this connection to be
dropped which in turn renders socket unusable and terminal unavaiable
for incoming calls until it sends next informational packet which may
happen several minutes later.
i would suggest changing return statement to some warning in log like
PTRACE(1, "Q931\twarning: NAT socket not (yet?) connected " <<
socket->Name() << " for endpoint " << GetEndpointIdentifier().GetValue());
espacialy that socket is forced to connected state right after setSocket
exits in CallSignalSocket::OnInformation()
Second issue is with ipphone KE1020 which i think is also known under
other names.
they are sending in RRQ something like this:
[..] nonStandardData = { nonStandardIdentifier = object
data = 18 octets { ADDR=192.168.2.100 } }
[..] endpointVendor = {
vendor = { t35CountryCode = 38 t35Extension = 0 manufacturerCode =
21845} productId = 16 octets { Koncept }
versionId = 5 octets { 2.19. }}
They were running perfectly with older gnugk versions (up to 2.2.5
afair) (however i'm not quite sure how when i look into code ;-), but
they seems to not like those new code which have been recently added to
RasSrv.cxx:
rcf.m_nonStandardData.m_nonStandardIdentifier.SetTag(H225_NonStandardIdentifier::e_h221NonStandard);
H225_H221NonStandard &t35 = rcf.m_nonStandardData.m_nonStandardIdentifier;
t35.m_t35CountryCode = Toolkit::t35cPoland;
t35.m_manufacturerCode = Toolkit::t35mGnuGk;
t35.m_t35Extension = Toolkit::t35eNATTraversal;
and there are several changes i'm adding a patch, sory for excesive
PTRACE inside but i have found it usefull. (patch is against todays
