Usually SIP registration goes like this:<div><br></div><div>1. FS-&gt;IPEL Register</div><div>2. IPTEL-&gt;FS Unauthorized</div><div>3. FS-&gt;IPTEL Register (yes, again, with additional credentials)</div><div>4. IPTEL-&gt;FS OK</div>
<div><br></div><div>You say that you was able to call iptel successfully, so FS is registered.</div><div>You just did not observed and did not provide SIP messages #3 and #4.</div><div><br></div><div><br></div><div><br><div class="gmail_quote">
