I currently manage over 100 Asterisk boxes and started the process of moving them to Asterisk 16 with PJSIP.
I have been testing the implementation with a number of SIP Providers. During outgoing calls, I have noticed that Asterisk sends multiple re-invites after 200 OK. This is not something we have seen happening before and its not something I am familiar with.
What I find strange is that the re-INVITE contains the same SDP and message body as the original INVITE. Moreover, one of our providers requires us to fix this.
I have researched the documentation and have been unable to find any reference to this behavior. Has anyone encountered this before please or am I missing something?
Thank you in advance.
