Hello,
I am working to create a SIP trunk in CCME 8.6 (c2851) and an ASTERISK server. Everything is fine but I have a doubt.
For incoming call to CCME (ASTERISK to CCME), Cisco always accepts calls even if ASTERISK server is not registered.
There is no security or authentication. I do not want encryption but I want that Cisco only accepts SIP calls from ASTERISK server.
I suppose that you can use ACL's but my question is "Is there anyway to configure a Cisco CCME that only accept calls from
registered devices?".
Thanks

May be you can try with IP address trusted list feature which is available from 15.X IOS
