[Freeswitch-users] Dynamic SIP Gateways to register with

Hi all, I have got one more question, I'm not able to find in docs: How could I dynamicaly add/change params/remove SIP gateways I have to register with (and the others - I shouldn't register with - too :-)? Like I see, gateways are defined in Sofia profiles - XML files. Are these files read periodically (at best on all call processing)? Or is there a way how to get mod_xml_curl into play? Or something completly different? :-) Any hints are very appreciated! Regards, kokoska.rokoska
