[Freeswitch-users] SIP/2.0 500 No session set by user

Mon Jun 28 05:46:33 PDT 2010

Hi guys,

I've got a problem with a Aastra SIP Phone. 

When I make a call to freeswitch from this Phone, I get an return SIP message "SIP/2.0 500 No session set by user". This occurs when I call from the Aastra Phone to a Cisco Skinny Phone (mod_skinny).

When I call from Xlite to that same phone, it just Works. Besides that, when I call from the Aastra to Xlite and vice versa no problem occurs (SIP to SIP). 

I've searched the internet on this and came on the Sofia-Sip website. There I found this message is generated by soa_static.c (line 1131). There it says:

  if (user == NULL)
    return soa_set_status(ss, 500, "No session set by user");

But what does it mean by "USER"? Can somebody point me in the right direction so I can find out why it's replying with No session set by User

Below i've attached the sip trace

Thanks in advance.

Regards,

Erik (wvds-nl)
