Thanks for your reply and explanation, samuel. But what do you mean by “If you want to send the initial call to both phone B and C, either in parallel or sequentally, then SER can easily do the job”? Could you please further explain on this or you can provide me so links to read bout this. Thanks!

Phone C need to know the dialog identifiers (dialog info package probably would help)of the call between A and B and then use replaces header to "intercept the call". I presonally haven't seen phones doing this. If you want to send the initial call to both phone B and C, either in parallel or sequentally, then SER can easily do the job. Just read a few mails or the getting started document and you'll see how to do this. Hope it helps, Samuel. 2008/2/20, roayu &lt;roayu(a)ctisys.net <mailto:roayu@ctisys.net>>: Hi there! Recently, I had setup a SIP environment with few sip phones, SIPphone A, SIPphone B, and SIPphone C. For instance, when SIPphone A called to SIPphone B, but B is not able to answer the call. Can SIPphone C answer A's call? I would like to know whether is SER able to have the intercept sip calls function? If yes, what module or configuration that I need to set? Thanks in advance!
