I am trying to get Polycom VVX501 phones to be able to send an “Intercom Call” between each other.
Which will make other phone answer automatically in handsfree speaker on “Intercom mode”.
When one of the Intercom phone places a call (in Intercom mode) it sets the SIP header Alert-Info field to “Intercom”.
Asterisk rewrites the INVITE and does not pass this field through to the other phone on the INVITE.
Is there an easy (or way) to simply pass this through so the phone on the far end gets this field?
I think this is all I need to make it work.
When the phone places a “normal” call to the same destination the calling phone does not
create this Alert-Info field in the header. which is what is wanted in a normal call.
I’m for whatever reason having a really hard time finding answers to this.
