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

[kaiduan xie]

 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.

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.
