agian i can recive incomming calls but i cant make out calls and what i need is some thing i dont undertand it which is
"" sending the required SIP headers"""

can you help me plz ?

You should ask them “and what are the the required SIP headers?”.

If your provdier has a good support you can work that with them in a live session debugging the sip session.

Your link is incomplete.
However: Either Your provider may assist You or - based on a documentation from Your provider - You may request professional support If You can’t get it running yourself …

so do you think that you cant help me ?

Who should be able to help You without any useful documentation (link incomplete, I told You) ?
Hence Your provider requires special SIP-Headers it’s Non-Standard and therefor the exact knowledge of the required headers is necessary to assist You …

thank you all guys , i will check and msg u back with result

cheers

thanks guys i had figured it out.

i created custom dial plan and put in it as the provider told me and it worked

cheers
