[Serusers] protocol fixup: missing ACK after 200 OK

I have a user agent that does not ACK after 200 OK. Is it possible to configure SER to generate an ACK and reply to 200 OK?

broken UA ---- INVITE ---> ser <---- 100 ------- ser ---- INVITE ---> gateway 183 183 ser <--- 200 OK---- gateway broken UA <---- 200 ----- ser <------ 2 way RTP ----------->

Call is mostly established, but broken UA does not ACK the 200 OK. Can we generate the following packet? ser --- ACK ---> gateway

This would allow the broken UA to interop. Can SER generate this ACK?

Thanks, Jamie Yukes
