I was testing the head version in GIT; I ran across a strange issue. The new config includes a "WITH_VOICEMAIL" definition I am not sure exactly how it is designed to work, but by default if the "usrloc" fails it creates a branch and goes to voicemail That part work correctly. It seems however if a phone is registered and the you get a busy, the failure route creates a branch but also retries the original RURI but I dont see a fork being created for the new branch to the voicemail server. Seems to just retry the original RURI. I am using the default config from the kamailio. repo. Any ideas. Thanks.
