than i advice you to do execute_on_ring and parse your 180 / 183 messages in search of SDP. If you have an SDP, open media channel.

what if you get 180/183 without SDP ? This is a legal call flow as well. after that you could get 200 OK with SDP .. what do you need to do in such cases ?

Yes tried that what Anthony said, its true it ignores the 183 w/o SDP but sends 180 to leg a instead for that duration,
i want to just ignore the 183 without SDP and not 183 with sdp; 183 with SDP should go to the leg a but not 183 w/o sdp.

Yes Tihomir false ring-back is a concern (i.e. 183 w/o sdp) and this is generated by one of the tier 1 provider having nextone sbc :(

Sam,

you actually found the answer to your question, as sip_ignore_183nosdp was implented by Anthony to achieve this:


So what you meant is that you tried it and it does not work ?
Did it actually change something in the callflow when you set it ?
Have you tried to export it rather than set ?

Hi,

This is in the dialplan.

Also Brian , 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 customer.
Here i want to block the 183 with SDP just like router as b2bua and send nothing to customer, and when actual 183 with sdp comes it should send .
