EXCEPTION: duplicate conversation id ...

[Former Member]

hi there.

i am in the process of implementing a new phone server

for SAPphone using NCo 2.0 and C# to replace our

old server which was implemented in C++ using plain RFC.

i have a SAPServerHost instance that handles some SAPServer instances.

in this SAPServerHost instance some server connections

are killed and the callback function OnServerException

gets triggered with the following message:

-

this error occurs more or less often when SPS_MAKECALL and the connected

SPS_GETCALLSTATE calls are executed.

can anyone explain to me what this message means exactly ?

i suppose its caused by the way NCo handles the server connections

since i commented out almost all of my own code in my implementation

of Sps_makecall and Sps_getcallstate and our old

server doesnt cause this problem.

is there maybe anything i can do configurationwise ?

are there any opinions/experiences/recommendations in general out there

about using NCo for a task like writing a server for SAPphone ?

thanks a lot for all responses,

fred

Hi,

May I ask you why creating a new sapphone server. What integration are you doing? We have some problem with the real time screen popup with standard SPS and tapi. Do you have solution for that?

Can we discuss in private?

OK.

I changed the PASSWD to uppercase and it

seems to work again.

Thanks a lot.

hi.

by replacing the librfc32.dll another problem evolved.

in my application i use a server proxy and a client proxy.

after starting my server host i periodically call

SPS_GET_LINES_PER_SERVER thru my client proxy.

after exchanging the librfc32.dll my client proxy

couldnt connect to SAP anymore.

i got an exception that said 'wrong user or wrong password'.

i didnt do any changes to my connect string !!!!

with this librfc32.dll version it works: 6403.3.55.4580

with this it doesnt: 6403.3.82.4763

could you give me a hint what the problem is now ???

thanks a lot,
