Re: [sipx-users] HA setup with more than 2 redundant servers

[Tony Graziano]

You can simulate this inside but I think pptp is a poor choice in that the
packets use a different IP address to be native to the network.

IPSEC AND OPENVPN are more suited to point to point and can properly tested
with the same network schema before rolling the systems out and over a vpn.

Pptp is really REALLY a poor choice here. You might not understand but the
routing and broadcast of how pptp works in a firewall advertises and routes
thins differently. It might be fine for some remote user but as a site to
site con it is somewhat crippling (IMO).

Re: [sipx-users] HA setup with more than 2 redundant servers

[Todd Hodgen]

First mention of a Tunnel between the servers.   Again, I'd recommend you
get this working in a lab first, without a tunnel.  Then add a tunnel
between servers and see if it breaks things.  You will likely see what is
breaking it very quickly, and without guessing.

The only thing that can raise issue is that the sites are connected via PPTP
VPN.
Latency is sub 10ms.
 
Will MS PPTP(the BEST implemetation so far - as it is transparent to all
protocols) be an issue?
 
We had issues with OpenVPn which is half ass implemetation.
 
Does the tunnel (which sipx uses) can have issues with PPTP? I can see that
sometime later the sending profile fails.

Re: [sipx-users] HA setup with more than 2 redundant servers

Have you tried setting this up in a lab, with your three servers, and
sipXecs as the DNS to see how they play together.  Get your lab successfully
built, and apply what you learn from that configuration to a network with
another DNS server setup.

Re: [sipx-users] HA setup with more than 2 redundant servers

[Nitin Mirchandani]

Of course I need to send profiles - But when its done, it starts failing in 
different ways.Each time error is different. If I switch off one 
server(redundant), and send profiels, it starts working again. Since its 
failing in different ways, and dns is correct (i have rechecked hundreds of 
times), I think sipx is unstable on 3 servers.

you always need to send profiles after the server pulls down it's configuration 
stuff...

Re: [sipx-users] HA setup with more than 2 redundant servers

[Nitin Mirchandani]

The problem is that if I add third server, second server goes ito 
"disabled'(ie, in server services - its disabed)Sometimes its third. Server is 
MS dns - with a separate domain which is not relicated.I have painstakingly 
entered the _sip entries with correct priorities. But then, Sip server works on 
dns thing - Its only phones which use SRV. I am talking about services not 
starting (failed resource, disabled etc). I will come up to phones (and SRV) 
when the system is stable (ie, both the secondary servers have serives running)

alright, everybody knows I'm going here...
sounds like DNS to me...
make sure tcp sip service records have higher (lower number) priority than all 
of the udp records.

test dns from all locations in the same manner a phone would get an ip and use 
dns.
you'll not want to rely on windows servers for dns at all locations.  you'll 
want to use bind views or separate dns zone files on each proxy to have phones 
pick their closest dns / proxy.

as long as addresses are routable, should work.  i think the gui will
let you add up to 4 additional server for up to 5, but after 3 the
chatter between the systems becomes detrimental to performance.
