[cisco-voip] SLP -- Multicast? Berbee IP Speakers across wan

[Lelio Fulgenzi]

I would go with a special VLAN for the berbee speakers. Especially, from what I remember, they can't do CDP and/or negotiate a voice vlan, so those network ports can easily be used by a PC (if they can reach) and hack your system. hack! hack.

  Is anyone out in internet land using Berbee IP speakers?

  are you also running CM 6.x?

  did you upgrade to SLP?

  Is it going across the WAN?

  Does it work?

  I have CM 6.1 and have upgraded the IP speakers to SLP since you can no longer put non-cisco files on the CM TFTP (thanks cisco).  So to get around this Berbee has you upgrade to SLP (which is a Multicast 239.255.255.253).  So it tries TFTP fails and goes to SLP.  Problem I'm having is that both the IP Speaker and IC both use the SLP Multicast address so my Cat 6509 doesn't want to multicast back to an address that is sourcing it.  I'm just curious if I'm the only one?

  I think I'm about to setup a new vlan just for IP speakers with it's own TFTP (IC) and get it working this way.  I can use SSMulticast but also an admin issue.

  TIA

  Scott
