Hi, The company I work for get toll-free numbers from Level3 via Bandwidth.com which are terminated on several Freeswitch servers using DNS SRV records. Annoyingly Level3 have a 'feature' where they will failover a call to a different server if the call is not answered in 25 seconds. In the UK, the provider we use has a similar failover setting, but as soon as early media is sent the fail-over mechanism is stopped and you can ring for as long as you need to. I have been told by Level3 that it is a known issue, but not something they can/will change, and that calls should be answered within 25 seconds. I tend to agree, however I forward calls to our customer's PSTN numbers, and they do not always answer within that time. This causes duplicate call records when the call fails over. For a call analytics company, this causes serious problems in statistics. Does anyone have any experience with Level3 and this strange behaviour? Thanks Tom
