<br>
quick question:<br>
I need to pass-through some headers from the A-Leg to the B-Leg, which<br>
are connected using PJSIP.<br>
Currently I do the following:<br>
<br>
[handler]<br>
exten => addheader,1,GotoIf($["${ARG1}" == ""]?3)<br>
exten => addheader,2,Set(PJSIP_HEADER(<wbr>add,Route)=${ARG1})<br>
exten => addheader,3,GotoIf($["${ARG2}" == ""]?5)<br>
exten => addheader,4,Set(PJSIP_HEADER(<wbr>add,P-Charging-Vector)=${ARG2}<wbr>)<br>
exten => addheader,5,GotoIf($["${ARG3}" == ""]?7)<br>
exten => addheader,6,Set(PJSIP_HEADER(<wbr>add,P-Visited-Network-ID)=${<wbr>ARG3})<br>
exten => addheader,7,GotoIf($["${ARG4}" == ""]?9)<br>
exten => addheader,8,Set(PJSIP_HEADER(<wbr>add,X-C-Params)=${ARG4})<br>
exten => addheader,9,GotoIf($["${ARG5}" == ""]?11)<br>
exten => addheader,10,Set(PJSIP_HEADER(<wbr>add,X-URI)=${ARG5})<br>
exten => addheader,11,Return<br>
<br>
[pcscf1]<br>
exten => _.,1,Dial(PJSIP/pcscf1/sip:${<wbr>EXTEN}@${SIPDOMAIN},,b(<wbr>handler^addheader^1,(${PJSIP_<wbr>HEADER(read,Route)},${PJSIP_<wbr>HEADER(read,P-Charging-Vector)<wbr>},${PJSIP_HEADER(read,P-<wbr>Visited-Network-ID)},${PJSIP_<wbr>HEADER(read,X-C-Params)},${<wbr>PJSIP_HEADER(read,X-URI)})))<br>
<br>
This works, but you'll have to admit, it's not the most<br>
readable-Version of an extensions.conf.<br>
<br>
Are there any better solutions around?<br>
<br>
Thanks,<br>
Carsten<br>
<br>
P.S.: I may have found an issue in Asterisk 13.x (LTS); if I send the<br>
right SIP-Message I can make it crash. I'm currently verifying, if it<br>
still happens with the latest 13.x release from GIT. If I can confirm<br>
it with the latest 13.x from GIT, should I post my findings to the<br>
dev-list or is there some security mailing list, as this would apply<br>
to all installations around there?<br>
