Can Link or S4B send non-anonymous requests to Asterisk?

Question

Skype

Hello. To connect Lync 2013 with Aster, we use a layer server with an old version of Aster, which was able to perform anonymous authentication. The question is, is it possible to somehow force S4B to configure a bunch of login-password to remove the extra padding to the aster?

Answer 1

The option of anonymous calls has not gone anywhere, version 13 of Asterisk also exists. Asterisk was conceived as a platform for free communication. If you add sip SRV to DNS and configure everything correctly, then this option will allow you to receive incoming calls from any public telephony server. But, it's bad practice to use this option if it's not needed.

allowguest=yes

You can set up a trunk between asterisk and lynk with port authorization, that is, asterisk will only allow incoming calls from a specific IP and port (IP lynk)

[trunk]
type=friend
insecure=port,invite
host=(IP LYNC)
fromdomain=(IP LYNC)
