Hello, We are running Freeswitch 1.4.8 on Ubuntu 12.04 LTS and encountering with some very specific telephone numbers (currently 2 telephone numbers) a disconnect when trying to call them or them calling us. (99%) of the calls work flawlessly). The symptom is that when we call the number it connects and the call is immediately dropped before we hear the first ring. From their side when they call us we see Freeswitch accept the call go through the process and before it starts ringing we see the error: Progress time out duration 5 seconds. I presume it is due to some delay in establishing the call final routing but how can I tell Freeswitch to add a few more seconds before giving up? Or is it some other issue? Any help would be greatly appreciated. Thanks in advance. cjb
