My question (because always if a call was dropped, PRACK has been in use):<br>
Is it a good idea to use a subsequent CSeq for the PRACK on Asterisk side, which is reused later on by the provider for the update (in this example)? Probably it shouldn't harm - but<br>
could this for some devices be nevertheless a problem? For now, I disabled 100rel support on Asterisk trunk side (it was on by default). Let's wait and see what happens ... .<br></blockquote><div><br></div><div>Purely from a sequence number perspective there is a local sequence number and remote sequence number, they are independent and could conceivably match up at times but that by itself should not cause an issue within the specification itself. I can't speak towards any issues or assumptions within the SIP implementation of the remote side though.</div></div><div><br></div>-- <br><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div style="font-family:tahoma,sans-serif"><font color="#073763">Joshua C.
