<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a requirement to normalise a number to an international E164 inside Kamailio.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In my scenario I’m receiving a call from “a platform”, and then making a call out to the same platform. I’m then adding some services to that call (e.g. recording it) on the way through.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The problem is that sometimes the number I receive in the FROM field in the initial invite from “A platform” has 44 at the front, but no +. “A Platform” is then rejecting the call back in from myself, because the FROM field isn’t formatted
correctly. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Scenario 1 – WORKS FINE – sometimes we see this.<o:p></o:p></p>
<p class="MsoNormal">PSTN -> FROM:<span style="font-size:9.5pt;font-family:"Arial",sans-serif;color:black;background:white">07700900000</span> -> A PLATFORM -> FROM:<span style="font-size:9.5pt;font-family:"Arial",sans-serif;color:black;background:white">07700900000</span>
-> ME<o:p></o:p></p>
<p class="MsoNormal">Call Centre <- A PLATFORM <- FROM:<span style="font-size:9.5pt;font-family:"Arial",sans-serif;color:black;background:white">07700900000</span> <- ME<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Scenario 2 DOES NOT WORK – sometimes we see this.<o:p></o:p></p>
<p class="MsoNormal">PSTN -> FROM:<span style="font-size:9.5pt;font-family:"Arial",sans-serif;color:black;background:white">447700900000</span> -> A PLATFORM -> FROM:<span style="font-size:9.5pt;font-family:"Arial",sans-serif;color:black;background:white">447700900000</span>
-> Aeriandi<o:p></o:p></p>
<p class="MsoNormal">Call Centre <- A PLATFORM <- FROM:<span style="font-size:9.5pt;font-family:"Arial",sans-serif;color:black;background:white">447700900000</span> <- Aeriandi<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Scenario 3 WORKS by fixing up the number by adding a +<o:p></o:p></p>
<p class="MsoNormal">PSTN -> FROM:<span style="font-size:9.5pt;font-family:"Arial",sans-serif;color:black;background:white">447700900000</span> -> A PLATFORM -> FROM:
<span style="font-size:9.5pt;font-family:"Arial",sans-serif;color:black;background:white">
447700900000</span> -> Aeriandi<o:p></o:p></p>
<p class="MsoNormal">Call Centre <- A PLATFORM <- FROM:<b>+</b><span style="font-size:9.5pt;font-family:"Arial",sans-serif;color:black;background:white">447700900000</span> <- Aeriandi (ADD a PLUS)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So I’m investigating if it’s possible to fix up the number and add the + in Kamailio. Clearly I could detect if the number starts with 44 and change this to +44, but this seems very brittle (what about other international numbers) – it
there a proper way to do this, or a standard module?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Unfortunately asking “A platform” to send me the “FROM” in a consistent format is not an option.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Many Thanks,<o:p></o:p></p>
