[SIPForum-discussion] Not Getting INVITE ACK

Hello Nitin

Are you running a trace with Wireshark/Ethereal?
If so, what does it make of your INVITE (i.e. does it class it as a valid
SIP message)?
Does it record anything coming back from the server?

Bitter experience of this kind of thing would suggest that there is
something subtly wrong with the format your INVITE, that is not immediately
obvious to you, or indeed to me.

Plus the other things that Vicky suggested.

Regards

Malcolm

Subject: [SIPForum-discussion] Not Getting INVITE ACK

Hi All

I am having a issue with INVITE. I mean to say whenever i am dailing
the no then my UA is just sending INVITE to the server but i am not
getting any response for the INVITE. I have already checked the logs
but not able to fine the reason for this. I am sending the logs in UDP
stream below. Please check and let me know why its happening.
