Pass SIP INFO between two connected SIP peers

Can Asterisk pass SIP INFO request to the connected peer? I have SIP phone connected to AudioCodes FXO gateway through Asterisk. The gateway sends SIP INFO in case there is another incoming call (call waiting service from CO line connected to the gateway). Is there any way to pass the information to the SIP phone? Currently Asterisk sends 415 back. Thanks in advance.

No. It is a a back to back user agent which does not use SIP internally.

I don’t believe it can pass MWI through, but I may have missed something, particularly in the latest version.
