Re: Getting started with Kamailio and Freeswitch

ChatGPT suggested adding this, and it does seem to get around the problem

if ($rU =~ "^[0-9]+$") { xlog("Routing number $rU to FreeSWITCH\n"); $du 
= "sip:85.10.4.2:5090"; route(RELAY); exit; }

So it seems that my Kamailio wasn't really setup for relaying calls 
elsewhere (eg Freeswitch). Maybe some magic module missing?

I should have said at the beginning that this was installed via a 
package manager, not compiled from source. Perhaps relevant?
