Samsung Officeserv 7400 PBX “Failed.Line Unavailable”

We’re setting up auto dialer with a Samsung Officeserv 7400 pbx. We have the sip extensions, and we can see they are getting registered with Voicent Gateway. However, when we try and send out a broadcast, we keep getting “Failed.Line Unavailable”. Also when we try and record a message by phone, by dialing the sip extension, Voicent picks up the call then hangs up immediately. Can you help?

Ensure that the Samsung Officeserv 7400 is using one of these voice codecs; G.711, 729A, or 723.1.

Based on the error logs provided other troubleshooting tips are.

1) Both problems seem to be related to some connection issue. Is the gateway computer on the same LAN as the PBX?

2) If not, check the switch/router/firewall programs in between.

In addition, check your PBX log files to see if there is any error.
