I am using 11.17.0 – and MulticastRTP. Doesnt seem to work with polycom phones as other devices receive my multicast just fine.

Is there something special to do to get multicast working with polycom phones?
(other than enable multicast on the actual phone).

Thanks

Jerry

phones?

Didn’t see if anyone had answered you or not on this, but Polycom uses their own form of MulticastRTP. It doesn’t work with Asterisk’s multicast setup. There is a company that makes a loud ringer/pager unit that can also be used to take in a sip call and multicast out to the Polycom phones. I haven’t tried it myself as I just use the loud ringer capability, but it does appear that it would be a workable solution. I
hesitate to promote the name here since this is non-commercial discussion, but let me know if you want to hear the actual product.

If mentioning Polycom is OK, I think mentioning a possible commercial solution is OK.

In that case, the product in question is the Algo 8180 SIP Audio Alerter. I will state that I have not used this particular functionality, but it is mentioned in the users guide, so in theory you could use it as a bridge between Asterisk and mulitcast on the Polycom phones. YMMV.
