Incoming Calls are not Working

[mwag]

Hi Folks,

While outgoing telephony is now working perfectly with my SBC, incoming telephony is not yet. In the case of incoming calls, these "rotate" between the SBC and SM and are not routed to the extension or the get acknowledged with a "busy". I see nothing at all on the incoming trunks from the CM. (Screenshot Attached).

The respective application is used in version 8.

Does anyone have any other ideas what I can check?

Perhaps start by looking at the adaptation for the SBC in the SMGR and see if your DID numbers are set up there.

The adaptation looks good to me..
But I still can't explain the connection, why dozens of calls on the SBC/SM can be seen in the trace from a single call - or why these calls are occurring with error codes 486 and 404.
