[Freeswitch-users] Unexpected BYE reason 488 after RE-INVITE

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?
