I managed to get rid of that 406. Thanks, Ken. I omitted *,Accept Header*, this time.

Although, I have included the authorization thingy in the INVITE request. Any idea, why its like that? Thanks in advance. On Tue, Nov 11, 2008 at 5:58 PM, Adeel Ansari <adeel.gnome@gmail.com> wrote:

Actually, I am just trying to build a minimal client/UA for Freeswitch. Do I need to go into 3pcc or something. I remember I did play with 3pcc but at that time I was implementing a sip stack and trying to come up with a minimal softswitch. Am I misunderstanding something?

It sounds like, I need to include codecs. I have tried the similar INVITE with a Voip provider directly, and send it with 0 content-length, and no sdp at all. In response I got whole lot of things like codec, and all. Therefore, I did the same for the Freeswtich too. However, I will try including codecs.

Thanks.

1. you need to include an SDP or enable 3pcc support on the sip profile... 2. the 3rd invite looks like it doesn't include any codecs (or atleast any I am familiar with)

Hi, I am getting 406, no matter what. I have tried 3 different INVITEs.
