Hi all
Kamailio <=> SBC <=> Interconnection
10.1.1.1 <=> i: 10.1.1.2 SBC e: 10.99.1.77 <=> IC: 10.88.88.1
|> i: 10.1.1.3 SBC e: 10.99.1.77 <=> IC: 10.88.88.2
At the moment I have the issue that our commercial SBC can only handle
n to 1 static ingress to egress mappings.
So basically I can tell the SBC: Do route everything you get from
Kamailio 10.1.1.1 received in 10.1.1.2 to IC peer: 10.88.88.1 and vice
versa.
So I need one internal SBC IP per ic peer.
But we want redundancy and load balancing. So IC peer (like the largest
telco in Switzerland) increased their redundancy and are reachable on 4
ip addresses via two independent exchanges.
Let's use 10.88.88.1 to 10.88.88.4
I discovered that our SBC would support Route header.
At the moment my dispatcher.lst looks like this:
1100 sip:10.1.1.2:5060 0 0 name="IC-A"
1100 sip:10.1.1.3:5060 0 0 name="IC-A"
But! Is there a possibility to set a route on the dispatcher list?
Like:
1100 sip:10.88.88.1:5060 Route:10.1.1.2:5060 0 0 name="IC-A"
1100 sip:10.88.88.2:5060 Route:10.1.1.2:5060 0 0 name="IC-A"
1100 sip:10.88.88.3:5060 Route:10.1.1.2:5060 0 0 name="IC-A"
1100 sip:10.88.88.4:5060 Route:10.1.1.2:5060 0 0 name="IC-A"
So I could use only one ip address on the internal SBC interface.
And I could extend this to further interconnections using only one IP
and have the SBC route according the route header received:
1100 sip:10.88.88.1:5060 Route:10.1.1.2:5060 0 0 name="IC-A"
1100 sip:10.88.88.2:5060 Route:10.1.1.2:5060 0 0 name="IC-A"
1100 sip:10.88.88.3:5060 Route:10.1.1.2:5060 0 0 name="IC-A"
1100 sip:10.88.88.4:5060 Route:10.1.1.2:5060 0 0 name="IC-A"
1200 sip:10.5.5.10:5060 Route:10.1.1.2:5060 0 0 name="IC-B"
1200 sip:10.5.5.10:5060 Route:10.1.1.2:5060 0 0 name="IC-B"
2000 sip:10.1.1.10:5060 0 0 name="Kamailio-Registrar-A"
2001 sip:10.1.1.11:5060 0 0 name="Kamailio-Registrar-B"
3000 sip:10.1.1.20:5060 0 0 name="Voicemail-A"
3000 sip:10.1.1.21:5060 0 0 name="Voicemail-B"
and so on to send call to the various IC via the same SBC ip with pre-set route?
The obproxy attribute is only for pings, right?
