[sip-comm] Can't connect to a Nuance server running SIP


#1

Hi all,

I've implemented a speaker verification system with Nuance Verifier,
running as a server accepting sip calls.

When I try to connect to it with sip-communicator i get the following
error:

27269 [EventScannerThread] DEBUG media.MediaManager - sdpData arg - v=0

Im connecting directly to the server in a private network. Nuance supports
G.711 (alaw and mulaw). So what Im doing wrong here?

Any hints or tips would greatly be appreciated!

Best regards,

Christian
