How to indentify SKYPE incoming callls in ASTERISK

Hello Team,

I have installed Asterisk 1.8 in my server. In that server we are doing International calling through PRI .So I want to block All skype incoming calls in my asterisk server . So how can we indeitify this is a SKYPE incoming call in CLI.
Please suggest.

Asterisk 1.8 is end of life.

There is no support for Skype for new users, except by using SIP to their servers. Please can you explain, in more detail, your relationship to skype IN.

For skype OUT, you would need to ask Skype for a list of numbers they control. I can’t see them providing that list.

I believe it has the word “Sykpe” in the UDP packets, but you’d need to filter them with a firewall, switch, or by using a SIP proxy.
