[OpenSIPS-Users] OpenSIPs generate PRACK

Tue Mar 19 17:53:17 UTC 2024

Some progress

Now I can reply the first 183 with the PRACK response but when the 
provider send a 180 ringing and I reply with another PPRACK response the 
provider reply with 500 Server Internal Error

Annex PCAP Capture.

Any hint is really appreciate.
