Could you help me with the following questions?
When I dial the number xxxx-xxxx, I get the following SIP signaling:
See that the provider is not sending 180 ringing.
My question is:
How do I send 180 ringing with 183 (SDP) in the call?
The signage should look like this below:
(Any 180 if ringing appear before or after the 183 (SDP), what matters is that the moment the 180 ringing is sent is the same as 183 (SDP).).
See I’m not talking about the Fake Ring, ring false because unfortunately happens immediately after the Invite, which makes it very automatic.
I need the 180 Ring comes with the 183 SDP, is this possible?
