[asterisk-users] Two IP addresses and a SIP Trunk

[Matej Mailing]

Hi,

we have a failover redundancy with two ISPs and an outside SIP Trunk
provider for the telephony. Since network failures of our primary ISP
line happen sometimes I would be interested into a solution where we
could use both IPs to connect to our telephony provider. I was talking
to them and they said they need to have our IP entered into their
system and that it must be only one IP. Therefore when there is a
failure on our primary ISP, I can call them and they change the IP to
our secondary IP - but this takes time and our phones don't work in
the meantime.

Could this be done automatically and if, how? We have two static IPs.

Thanks a lot.
