I've changed my router to a Juniper SRX from a Juniper SSG and have implemented load balancing with two ISPs. When either one of the ISPs is down, outgoing calls work. When both are connected, outgoing calls fail with the error: Call or Registration to 1112223344@(Ln.10000@Nexvortex) has failed. 0.0.0.0 replied: 408 Request Timeout; internal Incoming calls work at all times. Has anyone seen or solved this issue? Thank you.
