It can be a number:

http://www.kamailio.org/wiki/cookbooks/4.3.x/core#server_id

The use of server_id in location was added recently, for 4.3 series.

It is used for some other things as well, like generating some internal unique ids...

Cheers,
Daniel

Interesting, because ive never used server_id ..
should this be an integer, or can it be a string like the hostname of the box ?

Hello,

if you have several Kamailio servers sharing the same database in db only mode, then on each kamailio.cfg you can set server_id to a different value (is a global parameter). That value will be stored in location table. Then, nat keepalives will be sent by each server only for their server id.

Cheers,
Daniel

Looking for some doc that describes how the new columns in 4.3.x location table is supposed to be used. Can find some email discussions about this, but seems no formal doc exists. Would appreciate if someone can provide an explanation.

Thanks
