<br>
If you use the opensips default script, your opensips will accept calls from any other external SIP entities (call targeting a local opensips subscriber).<br>
<br>
If you want to configure your opensips to accept foreign calls only form a specific IP address, you can use the permission module, with address table to implement IP-based authentication.<br>
<br>
Best regards,<br>
Bogdan<br>

Hi everyone,<br>
<br>
I am a newbie with SIP-Trunk in OpenSips. <br>
I have a Cisco Communication Unified Manager and a OpenSips Server running in two different Virtual Machines.<br>
<br>
I would like to have a SIP trunk in between them "Cisco Communication Unified Manager and OpenSips Server". <br>
Therefore, I can make a call from OpenSips Server's SIP Clients to Cisco IP Phone. <br>
What should I need to add into opensips.cfg configuration file?<br>
<br>
I hope you can give some simple examples how to do it. <br>
I look forward to hearing from your advise asap.<br>
<br>
Thanks<br>
Regards,<br>
-Steven.<br>
