cucm6.1 how to implement like this:
1) Remote end(an old fashion intercom), dials in, 3 phones should auto answer the call, the intercom is able to speak to these phones.
2) After the intercom claims which phone he needs to talk to, that phone should continue the conversation, however, all other phones should quit immediately.
I believe paging on Ipsession can do For step 1), however, no idea for sequential setup. Any information is appreciated.
