Thanks for ur reply. I am using CUCME- 4.3, and I'll rephrase my question - I suppose 7937 supports only one line(dual)so at a time i can only make or receive upto 2 calls only. Is it possible to make or receive more than 2 calls on it so that i can have more than 3 party conferecing.
exact same thing whether it's CME or CUCM, 7937 has nothing to do with how many users can be in a conference. that depends on CFB config
indeed, it's not possible to make more than 2 calls per line, CME 4.3/7.0 introduced octolines but i haven't configured a 7937 on those versions. but then again, conferencing does not require more than 2 calls per line
