Hello, I have two different failure routes. One of them is for internal calls (function: mailbox on timeout or busy) and the other one is for PSTN calls (function: failover). If a user makes a call to a Virtual Number of another client (MyUser1 --> PSTN --> MyUser2), the failure routes are "mixtured". Example: Call from 44441 to 001234567890 --> Gateway --> Gateway forwards it to 44442 After a couple of seconds, the failure_route 1 (for internal calls) goes into the failure routing with the number 001234567890... but obvially there is no client with the number 001234567890. Any hints? Sebastian
