Balst a Multiple SIP IP Speakers

Unanswered Question
Nov 3rd, 2009


I have deployed 10 IP Speakers for paging purposes on UC520, I have managed to call each one to page, I tried to create a Blast group and add the SIP extension to it but it didn't blas the speaker at ones, is there any way we can call all sip extension at onces? or can I create a shared sip DN for all sip extension?

I have this problem too.

The phones are called all at once when you do a blast group, but only one of them can answer.  What you need is a multicast stream and for the SIP IP Speakers to make this work.

Cyberdata has a unit that can understand the multicast stream and it is SIP.
