Guessing based on NO information provide that the refer is sent with URL that fails to include transport=tcp, which by will make it default to UDP. /b On Mon, May 9, 2016 at 11:02 AM, Alexander Haugg <Alexander.Haugg@c4b.de> wrote:
The Connection between SIP Client and FreeSwitch works with TCP only!
Why there are difference from a refer to an outbound call and a refer to an inbound call? In the Trace I can see, the refer looks like equal.
What can I do to make sure the FreeSwitch send the Notify in TCP? The Client have no UDP Port open for SIP.

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.

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:
FreeSWITCH Version 1.7.0+git~20160502T014035Z~96e963d3eb~64bit (git 96e963d 2016-05-02 01:40:35Z 64bit)
