You can't continue in bypass media mode because (wrong) media IP/port already sent to your downstream. Even if the second gateway completes the call OK, you will get one way audio. So either proxy the media or fail the call. On Wednesday 03 February 2016 15:07:29 Victor Chukalovskiy wrote:
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/${destinat ion_number}"/>
Many thanks, -Victor
