[asterisk-dev] Is ast_channel->uniqueid really unique ?

[Oded Arbel]

>From what I understand, the uniqueid field in the ast_channel is unique
for a single installation of Asterisk, and is composed of the unix
timestamp at the creation of the channel plus some running counter. 

The problem I'm having, is that I don't think that a channel's uniqueid
is unique across multiple Asterisk installations - under some very
common behaviors of a multiple Asterisk installation, some channels
created on different Asterisk instances will have the same uniqueid.

I'm thinking about changing the uniqueid generation algorithm to
something that generates ids that have a high statistical probability to
be unique across multiple instances of Asterisk given some reasonable
assumptions (for example - that there are less then a few thousands of
Asterisk instances to be considered). I'm not looking for a truly
globally unique identifier, just unique enough.

Do you think that this is doable/interesting/good idea ?
