Hi!

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?

Regards,

Igor.
