H-4 INSTALLING TELEVANTAGE
I cannot get SIP calls to work.
Have you followed the step by step instructions in Chapter 14 of Administering TeleVantage?
This chapter contains the majority of the information you need to know in order to get SIP calls
to work.
Is your Dialogic board configured with a host-based VoIP stack?
You can not use SIP with an embedded H.323 stack, so be sure that your IP boards as configured
in the DCM are using a host-based VoIP stack. Some boards do not support host-based VoIP
stack—to verify if your board does, see the Trunk Resources by Board table in Appendix E in
Installing Dialogic Telephony Components.
I am using SIP and H.323 and my IP Spans are configured properly but I can't
place SIP calls.
Be sure to create your H.323 Span first so your H.323 trunks have lower numbers than your SIP
trunks (in other words, the H.323 trunks are listed above the SIP trunks in the Device Monitor.)
Without this order, the configuration will not work properly. To resolve this problem, edit your
H.323 and SIP spans in the TeleVantage Administrator and change each span’s starting trunk
number so the SIP and H.323 trunks are in the proper order. Then restart the TeleVantage
Server.
I changed my SIP span's number of trunks. Now the SIP trunks do not seem to
be working.
You must restart the TeleVantage Server after changing the numbering of SIP or H.323 trunks
in a span.
Do I have to restart a SIP span after I changed any of its settings?
Most settings take effect on the next call—you will be prompted to restart the span for the few
settings that do not take effect right away.
Important:
You must restart the TeleVantage Server after you create or delete a SIP span, or
change the span's IP address, port, or number of trunks in the span.
I have created a SIP span and restarted the Server, but all of my SIP trunks show
up in the Device Monitor with a status of “No loop current.”
Check TeleVantage Windows event log. The problem is likely to have been reported there.
