Hi,

Thank you for your answers.
I could move forward with sip_unhold_nosdp=true so now FS replies with the initial proposal in 200 OK when an INVITE without SDP is received.

Now that's the UA2 that sends the BYE...but not clear why yet.

Regards,

Igor.

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.
