Are you using a mobicents server? Try to describe better what is the issue and the environment of your application...

I have two networks but they are connected to each anther
Everything worked fine but the invite when I accept invite

My problem it's like this :

S R

---------------invite----------->
<-------------Ringing---------
<-------------ACK for inv---
---------------BYE-----------> why after receiving accept sender sending bye and show on the sender site response 501 not implemented
<-------------ACK-for-BYE
---------------ACK----------->

I tried anther solution to send session progress before sending accept for invite but the same maybe am not using it right if that so Plz help with this issue.

Note:
1- Am using two network and they connected to each anther.
2- I tried send invite from my computer to SIP or Cisco Telephone
And no problem accrued the problem only when I sent invite from
My software to my software.

Can you provide us with which Mobicents Server you're using (SLEE or Sip Servlets) and which version + log files and possibly wireshark traces ?

Also can you give us the call flow of what you expect ?

For Mobicents i realy i don't know what it's mean
But we are using SIP Server
Cisco call manager 6.1
There is no log files and wireshark

---------------invite----------->
<-------------Ringing---------
<-------------ACK for inv---
---------------ACK----------->
and the session initiated correct that’s what we need.

It's very hard to tell without any log file nor copies of the requests responses exchanged.
My first guess would be that they cannot agree on setting up the media session, (Check the SDP of the messages exchanged to see if that could be it.) so one UA terminates the dialog just after the ACK has been received

I guess you're on your own here. Without more information(log, traces, messages exchanged etc) I cannot help you out
