Hey guys, i have setup 2 PBX systems that connect to two seperate routers, the routers have a virtual HSRP address of 10.10.10.5 and the Systems have the local IP of 10.10.10.5, however the softphones that i have seem unable to register to the address. Im using the HSRP address as i need it to switch to the second PBX incase the link goes down. Do you know any reason as to why this wouldnt register? Everything Pings everything so its not a conncetion issue? Could 3CX have some sort of firewall or rules in place to not accept the HSRP virtual address shared by the routers?
