No, it's just 2 networks which can go up and down under different
conditions.
There is nothing special about them.
(They could be both wireless but not necessarily)
There are just effectively 2 gateways, and each gateway goes to a
different
network. Each network could be a completely different service provider.
SIP UA---------------|-------192.168.0.1 GW1 ROUTER--external IP1-->
ISP1
192.168.0.254 |-------192.168.0.2 GW2 ROUTER--external IP2-->
ISP2
So for making a call, for example:
1. only GW1 has a connection to ISP
2. route call from SIP UA via GW1
3. call is still up and GW2 now has a link to ISP2
4. call is still up but GW1 loses link
5. (what I want) SIP and RTP continue seamlessly to use GW2 for
the call
The SIP UA user should have no idea that call is flowing through
different router.
Is this possible?
I would assume that similar (yet totally different) technology is used
for SIP mobile phones?

Hi
I think you need to use a combination of High Availability SIP servers
and Interworking Gateways to switchover from one network to another or
to switch from one server to another in case of a server breakdown.
For a more detailed explanation, could you elaborate your questions as
to between which networks you want to interwork and what u mean by
network going down - is it a particular server (master server) going
down and u want to seamlessly switch to slave (backup server)?
Thanks
Regards
Ranjit

If you have a SIP call and you have two fully independent and unreliable
networks, what technology can be used to automatically/seamlessly switch
a live call from network to another (as one network goes down)?
