The first reINVITE with inactive looks like a hold, the second reINVITE without SDP looks like a resume, what is the third reINVITE for? Does FS receive ACK for the third reINVITE? I think if FS returns sendonly for reINVITE without SDP, FS will not receive BYE. /Kaiduan On Wednesday, June 22, 2022 at 08:14:08 a.m. EDT, Igor Potjevlesch <igor.potjevlesch@gmail.com> wrote: Hello, No idea?

I cannot figure out why my call is disconnected in this scenario: UA1 --> FS --> GW --> UA2 (I think it’s a Cisco Phone and/or CUCM) UA2 sends a first RE-INVITE with media attribute "inactive". FS is replying with 200 OK inactive. Then, UA2 sends a second RE-INVITE without SDP. FS is replying with 200 OK inactive. Then, UA2 sends a third RE-INVITE without SDP. FS is replying with 200 OK inactive. And just a couple of ms after, FS sends the BYE with 488 No answer to offer. Do you have any idea of the origin?
