I have the following question: I just installed two Asterisk servers in a failover configuration (with Hearbeat). I only get my SIP phones working after having them register with one of the servers. I guess this is due to the “allowguest=no” setting (didn’t get the chance to test the opposite). However, since the phones need to register, they won’t work right away when the Asterisk service fails over to the second node. The phones need to wait until the expiration of the registration period. Is there any other way to fix this, except by setting the registration time as low as possible?
I should also mention that the SIP service will be presented on the internet as well.
