Hello,

we have the problem with us in the company that we can bring neither a C475 IP still another S685IP at the AGFEO Lan module 510 to running.

All the same we try which combination, it is always indicated “Registration failed”. I do not think that the error from AGFEO proceed, since a SIP Client on the computer installs problem-free at the AGFEO announce itself immediately could.

Neither Siemens nor Agfeo were particularly helpful in its remarks! Please can someone help us here?

Thanks!
Marco
