Hello, A downstream carrier would accept INVITE, send 183 w/SDP, and almost instantaneously respond "503". This kills the call not letting re-route to the next carrier. Without calling any specific names, this seems to become more common. Unfortunately, often the offending carrier is a few steps down the call path and I can't reach them with a cluebat. Is there a way to make FS not fail the call and try the next route if using LCR as per below? Note that we are in bypass_media mode: <action application="set" data="bypass_media=true"/> <action application="bridge" data="lcr/lcr_profile/${destination_number}"/> Or to keep it simple, forget LCR for a moment, can we make it go to gateway_2 in the following example if gw1 returns "183" followed by "503"? <action application="set" data="bypass_media=true"/> <action application="bridge" data="sofia/gateway/gw_1/${destination_number}|sofia/gateway/gw_2/${destination_number}"/> Many thanks, -Victor
