rfc3326 - I believe it's valid in any packet, you can potentially have a Reason passed back before the end of the call.

It's the BYE that's hanging up the call not the 200 OK, but that could be an interop problem where a device doesn't expect the Reason in the 200 OK.

I have a trace of one leg only I can try to capture both legs.
But a 200 OK with a Reason header is a valid SIP message (below 200 OK forwarded by FreeSWITCH) ?

I have a strange issue: some calls are dropped with a 200 OK containing the "Reason" header.
Is this valid?
The message flow is:

CUSTOMER ----     FS

INVITE ->

        <- 100 Trying
        <- 180 Ringing
        <- 200 OK (containing the Reason Header)
ACK ->

after some seconds...

BYE ->
BYE ->
BYE ->
BYE ->
BYE ->

The 200 OK sent by FreeSwitch contain a "Reason Header":

Reason: Q.850;cause=16;text="NORMAL_CLEARING"

And the call seems dropped and not connected in FreeSWITCH.
For the customer side the call seems connected with 200 OK (the customer ignore the Reason).
After some seconds, the customer try to disconnect the call with BYE but these messages are ignored by Freeswitch because the call was been already dropped.

It's valid the Reason inside the 200 OK? It's possible that this 200 OK has been forwarded by Freeswitch from the outbound leg.
Any advice for that?

Stephen
