Bug with REFER and TCP

[Diego Betancor]

Hello,

I am using a spa508g with 7.4.9c.

I think I have found a bug.

I use TCP for signaling.

I receive a call,I send a REFER using blind transfer. The phone first send a invite to put the call in hold (as soon you hit bfer), then the refer. If I then take the call out of Hold, about 10 seconds latter the phone closes the TCP conection. Not that it dislikes the hold ans send a BYE, no it closes the whole TCP conection.

I am attaching a whireshark capture.

Thank you, Diego

Update:

The 202 Accepted answer to the REFER was misconfigured. Still the fact is that if it doesn't get a valid answer to the REFER the whole TCP stack crashes.
