Hello,

if there are many interested, maybe would be a good idea to try to collect such details per phone and scenario type, like:

- direct connection to server (nat and no-nat)
- connection via outbound proxy (nat and no-nat)

We can make a wiki page for it. If you do some measurements and share them here (not for all cases, only for what you need), I will create the wiki page and try to add more from some of my deployments.

Cheers,
Daniel

this depends a lot on your environment as well as devices that are used,
because size of username, domain, contact, path header, call id, etc.
have direct impact in the size of the record.

The best way to estimate is to register 1000 phones, get the size of
used shared memory. The register 2000 phones and then get again the size
of used shared memory. Make the difference and divide by 1000, then you
should get a fair estimation of a location record. Of course, assuming
no other traffic is done through the server that could cause use of
shared memory.

Cheers,
Daniel
