Securely Using Avaya IPO with SIP Jxxx phones on Internet

Securely Using Avaya IPO with SIP Jxxx phones on Internet

(OP)
Anyone have any good/solid information on properly securing the IPO (500v2 on 11.x) to allow J179 SIP phones to connect over the Internet? I would like to use TLS and ensure that only phones with the cert can connect and try to log in but I can't find any good docs on the entire process from start to finish.

RE: Securely Using Avaya IPO with SIP Jxxx phones on Internet

Well, it's up the client to trust the server's certificate. It's only a security feature on the client side that it refuses the server certificate if it's not trusted. A hacker isn't going to care and will send SIP registers thru anyway.

IPO doesn't support mutual TLS where the phone requires an identity certificate to setup a TLS handshake. Session Manager and the SBC allow for that.

Best you can really do is TLS, SRTP, and use the security settings to lock out an account after X tries
