[Users] Re: [Devel] how to prevent concurrent calls per subscriber?

Hi Raymond,

try this in failure route:

failure_route[x] { log(1,"--inside failure route\n"); if (t_check_status("(404)|(487)")) { log(1,"--status is 404 or 487\n"); avp_db_delete("$from","s:/inuse"); # no need to load before } exit; }

watch the log messages and the mysql queries in the logs.

HI Andrei,

Finally get the avp_check working, we have not problem adding a entry using avp_db_store now. But how to catch SIP 404 not found message and avp_db_delete the entry in database? We've tried

if (t_check_status("404|487")) { if (avp_db_load("$from","s:inuse/inuse")) { avp_db_delete("$from","s:/inuse"); } exit(); }

In failure_route, but it doesn't seem to catch the 404 status message. Any idea?

Thanks

Ray

Hi Raymond,

this is a runtime error. it means that you try to check via "avp_check" two avps which have different types of values (int and string). my guess is that the problem is around :

avp_write("s:inuse","$intinuse");

if (avp_check("s:limit","gt/$intinuse/g")) {

avp_write will actually write the "s:inuse" string into $intinuse AVP and not copy the value (not sure which is the intention).

Use avp_print() before each "avp_check" to see the values (use debug=6).
