This can happen based on the content of the refer, and could be normal based on the content of the refer. The transport of the original call is not related. On Monday, May 9, 2016, Alexander Haugg <Alexander.Haugg@c4b.de> wrote:
Hi all,
The scenario is:
- The registered SIP Client make an outbound call
- After a connect the client send a refer to a new destination (Blind Transfer)
- The 202 accepted is correct as tcp sended
- The Notify (sipfrag 200 OK) and the following Bye will send via UDP
If I do the same with an inbound call, it works successfully.
Is it a Bug?
My Freeswitch version is:
