Note: forwarded message attached. Klaus, I posted this mail to the SER dev list yesterday and did not get reply for that. So i am sending this to you off list. Could you please take a look at this and tell what is going wrong? I diagnosed it further and found that SER crashes because of SIGSEGV when we modify the uri. Any help in this regard would greately be appreciated. Regards, ===== Girish Gopinath &lt;gr_sh2003(a)yahoo.com&gt; __________________________________ Do you Yahoo!? Friends. Fun.

SER on 5060 and Asterisk on 6060. The role of Asterisk is here to play the ivr messages. The calls land on SER and it gets the appropriate context from a module and t_relays it to Asterisk. This is working fine, but we experience crashes with SER after every 20-30 attempts. Our efforts to figure out the problem were not succeeded. I am attaching herewith relevent parts of my ser.cfg file, and the routine from the module that queries for the appropriate site context. Can anyone please verify the code and tell where the problem is? Any help on this regard would greately be appreciated. This is from ser.cfg file: modparam ("ivrtest", "db_url", "mysql://ser:heslo@localhost/ser") modparam ("ivrtest", "proxy_domain", "192.168.68.20") modparam ("ivrtest", "media_server", "192.168.68.20:6060") if ( method == "INVITE") { sl_send_reply("100", "Trying"); log(1,"Processsing call 1\n"); if (uri =~ "sip:[0-9]{10}@*"){ if (! get_ivr_context("1")) { sl_send_reply ("404", "Not Found"); drop (); break; } t_relay(); log(1, "Context Relayed\n"); break; } } --------------------------------------------------------------------------- This is the routine from the module that serves the request for ivr context: int get_ivr_context (struct sip_msg *msg, char *p1, char *p2) { str uri, strval; char tollfree [15], newuri [60], sqlcommand [150]; db_res_t *res; db_row_t row; uri = msg->first_line.u.request.uri; /* Expected toll free:- "sip:12345678900@blah..." */ memset (tollfree, 0x00, 15); strncpy (tollfree, uri.s+4, 11); strval.s = malloc(strlen(tollfree) + 1 ); strcpy(strval.s, tollfree); strval.len = strlen(strval.s); memset (sqlcommand, 0x00, 150); sprintf (sqlcommand, "SELECT sitename FROM siteinfo, pbxivr WHERE siteinfo.siteid = pbxivr.siteid AND pbxivr.tollfreenum = '%s'", tollfree); #if 0 fprintf(stderr, "Q: %s\n", sqlcommand); #endif db_raw_query (h, sqlcommand, &res); if (RES_ROW_N (res) < 1) return -1; row = RES_ROWS (res)[0]; if (! res || ! row.values) { db_free_query(h, res); return -1; } else { /* New URI: "sip:sitename@192.168.68.20:6060"*/ memset (newuri, 0x00, 60); sprintf (newuri, "sip:%s@%s", row.values[0].val.string_val, media_server); uri.s = malloc (strlen (newuri)+1); bzero (uri.s,strlen (newuri)+1); strncpy (uri.s, newuri, strlen (newuri)); uri.len = strlen (newuri); msg->parsed_uri_ok = 1; set_uri (msg, uri); } if (db_free_query(h, res) < 0) return -1; return 1; } TIA, ===== Girish Gopinath &lt;gr_sh2003(a)yahoo.com&gt; __________________________________ Do you Yahoo!?
