Hi, how can i ignore 183 without sdp, what happens is the provider sends 183 without sdp and by applying "<action application="set" data="sip_ignore_183nosdp=true"/>" the FS sends 180 to the leg a. Here i want to block the 183 with SDP just like router as b2bua and send nothing to leg a, and when actual 183 with sdp comes it should send . Its because, providers are sending false signaling by sending 183 without sdp,and it hampers while @ production, Although by cisco sbc i have done this but i want to do it by FS, Take a scenario, when call is send 183 without sdp for 10 secs and then followed by 183 with sdp ( actual signal), but when some one dials invalid number it rings for 10 secs and then gives SIP cause 404, which is bad from the providers. So this is the reason i want to block it. Most of the providers do this, the way out is blocking. I have got an advice from Tihomir to do "execute_on_ring and parse your 180 / 183 messages in search of SDP, once you get 183 without SDP do not send it back to leg a and send signal only when you got 183 with sdp or 180 " And this could be valid call flow. This happens in many cases where the provider is having nextone as a sbc and that too tier 1 ! Regards Sam
you need sip_ignore_183nosdp=true set on the b leg not the a leg. Put it in the dial string in {} {sip_ignore_183nosdp=true}sofia/foo/foo@bar.com On Fri, Jan 28, 2011 at 12:41 AM, Sam <u2nsam@gmail.com> wrote:

Hi,
how can i ignore 183 without sdp, what happens is the provider sends 183 without sdp and by applying "<action application="set" data="sip_ignore_183nosdp=true"/>" the FS sends 180 to the leg a. Here i want to block the 183 with SDP just like router as b2bua and send nothing to leg a, and when actual 183 with sdp comes it should send .
Its because, providers are sending false signaling by sending 183 without sdp,and it hampers while @ production, Although by cisco sbc i have done this but i want to do it by FS, Take a scenario, when call is send 183 without sdp for 10 secs and then followed by 183 with sdp ( actual signal), but when some one dials invalid number it rings for 10 secs and then gives SIP cause 404, which is bad from the providers. So this is the reason i want to block it.
Most of the providers do this, the way out is blocking.
I have got an advice from Tihomir to do "execute_on_ring and parse your 180 / 183 messages in search of SDP, once you get 183 without SDP do not send it back to leg a and send signal only when you got 183 with sdp or 180 " And this could be valid call flow.
This happens in many cases where the provider is having nextone as a sbc and that too tier 1 !

I have got an advice from Tihomir to do "execute_on_ring and parse your 180 / 183 messages in search of SDP, once you get 183 without SDP do not send it back to leg a and send signal only when you got 183 with sdp or 180 " And this could be valid call flow.
This happens in many cases where the provider is having nextone as a sbc and that too tier 1 !
