[asterisk-users] SIP Presence across two servers

[Lincoln King-Cliby]

Hi All,

We've been running Asterisk for years in our offices but just recently replaced an Asterisk Appliance* in our smaller office with an actual server, upgraded the server in hardware in our HQ location and upgrading both ends to 11.5.0 with Gareth's patch for Cisco phones.
99.99% of our endpoints are Cisco 7961Gs.

Each office is more-or-less standalone for ease of management and fault tolerance but we have a unified dialplan and SIP "trunking" from site to site via our VPN.

Everything presence related works wonderfully for local users, but I'm hoping there's a way we could get presence for the people "at the other end of the pipe" fairly transparently.
We have a lot of cross-office collaboration, and our office manager/receptionist (who has the battleship of a 7961G+7914+7914 BLF) would love to "at a glance" know if the remote folks are available for a call or not.

I'm sure this has been covered, but my Googlefu us turning up a ton of redundant, old, and deprecated information so I've resorted to asking here.
>From what I have found it sounds like it may be "easier" with IAX2 but my experiments with IAX2 haven't yielded wonderful results and management prefers "SIP everywhere"

If anyone has any pointers I'd greatly appreciate it - thanks in advance!

Lincoln

*- One of the worst IT decisions I've made for better or worse. Looked good on paper; in practice not a good idea for anything beyond a very simple SOHO.
