is_present_hf error on select
by Kyle Kurz 30 Mar '15

30 Mar '15

I'm trying to use the is_present_hf function to detect the presence of a user-defined header and getting the following errors in my Kamailio logs: 2(12149) BUG: <core> [select.c:426]: run_select(): Select structure has not been resolved 2(12149) ERROR: <core> [lvalue.c:416]: lval_assign(): assignment failed at pos: (99,58-99,58) 2(12149) ERROR: <script>: A quick Google search yielded no results for why this could be happening. Originally, I had my code in route[REPLY], but noticed that was not one of the paths it was listed as available in the textops document, so I moved it to request_route, but got the same errors. Does anyone have any feedback on how to move forward? My code snippet is below: if (is_present_hf("X-Digium-AppServer-Response-URI")) { $var(a) = @hf_value.X_Digium_AppServer_Response_URI[1]; xlog ("\n\nHERE RESPONSE URI $var(a)\n\n"); } Thanks, Kyle -- *Kyle Kurz* Digium, Inc. · Senior Software Engineer 9115 Brown Deer Rd · San Diego, CA 92121 · US direct +1 858.537.1166 Check us out at: http://digium.com · http://asterisk.org <http://www.asterisk.org/>

Reload htable
by Grant Bagdasarian 28 Mar '15

28 Mar '15

Hello, I need to reload a htable from the database when a certain condition is met inside my kamailio script. I found the htable.reload htable RPC command, but is it possible to run this from within the script? Is there perhaps another way to force reload the htable inside the script? Thanks, Grant

Routing PSTN calls from Asterisk through Kamailio to UAC & loose_route
by Anthony Messina 27 Mar '15

27 Mar '15

I've been working on integration of Asterisk and Kamailio, currently on the same host with different ports, and have come across a problem with calls that originate from the Asterisk side (PSTN/DAHDI) and route through Kamailio to a SIP UAC. In short, when the SIP UAC (10.1.1.9) sends the BYE, loose_route() is returning -1 and the BYE is routed back to Kamailio (10.1.1.1:5060) instead of Asterisk (10.1.1.1:5080). I am using the stock WITHINDLG route configuration. RR module settings are as follows: modparam("rr", "enable_full_lr", 1) modparam("rr", "append_fromtag", 1) The BYE from the SIP UAC contains the following Route header which only contains the contents of Kamailio's Record-Route header. I have attached the full sip trace for review as well. Route: <sip:10.1.1.1;lr=on;ftag=2400d939-de0b-4456-9e01-f9a3302f3e25;nat=yes>. What would be the best method to resolve this issue in either Asterisk or Kamailio? Should I manually add a Record-Route header for the Asterisk host:port to Kamailio config? Is there something to be done in Asterisk? Thanks. -A -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E
