[Asterisk-Users] Re: DUNDi .... Halfway and CLUSTERING

[Watkins, Bradley]

Do you mean the peristence of connecting a specific phone to a specific
server?  If so, then it's relatively easy.  The ldirectord has a persistence
setting that does that.  If I'm misunderstanding you, then could you explain
further what you mean?

Regards,
- Brad

Brad,

How are you able to overcome the Call-ID stickiness problem when
loadbalancing with Ultramonky? As I understand it LVS does not properly
support SIP in that it doesn't always use the same source path.

regards,
David
