<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>In my old telco days (SS7), if I was wanting to hand back a
call to the network for transfer to a different PSTN number, there was a
specific SS7 action I could take, which send the call back to the network,
which in turn then routed the call appropriately. It added a transfer-number
into the SS7 headers so that the originating number, dialed number and transfer
number all stayed to specs, and everyone was happy.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>In SIP/Asterisk, it seems that I have to hairpin/trombone
the call (to have at least the control packets go via my SIP server), and use a
Dial out to the far end.<o:p></o:p></span></font></p>

font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>So – is there a way of handing the call </span></font>back
to the network in asterisk ?<o:p></o:p></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>My detailed problem is this: When a call comes in, I want
to send it onto users mobiles, if I hairpin the call that’s OK, except
the CLI needs to be that of the originator (from the USERS point of view) so
they can decide if they want to accept the call.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Here in the <st1:country-region w:st="on"><st1:place w:st="on">UK</st1:place></st1:country-region>,
this is where the issues begin… the carriers here don’t like
it if your sending CLI for other countries, that don’t match what they
think they should receive from that connecting carrier. Eg, if a call coming to
them is 13 digits, but they only expect 11 from that carrier, then they cut the
digits. This turns a US originated call into a Southampton UK originated call!<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>So I was hoping that handing the call back to the network in the
traditional sense would make it their problem and not mine… lol<o:p></o:p></span></font></p>
