hello, I tried to test SER with GettingStarted.pdf document, But now I have trouble on "Chapter 9. PSTN Gateway Connectivity". I made ser.cfg like this chapter. Then I try to restart SER, SIP clients didn't authorize. Here is trace log. 2(3926) SIP Request: 2(3926) method: <REGISTER> 2(3926) uri: <sip:191.0.0.2> 2(3926) version: <SIP/2.0> 2(3926) parse_headers: flags=1 2(3926) Found param type 232, <branch> = <z9hG4bK-d87543-3e309a0333127c58-1--d87543->; state=6 2(3926) Found param type 235, <rport> = <n/a>; state=17 2(3926) end of header reached, state=5 2(3926) parse_headers: Via found, flags=1 2(3926) parse_headers: this is the first via 2(3926) After parse_msg... 2(3926) preparing to run routing scripts... 2(3926) parse_headers: flags=128 2(3926) DEBUG:maxfwd:is_maxfwd_present: value = 70 2(3926) DBG:maxfwd:process_maxfwd_header: value 70 decreased to 16 2(3926) parse_headers: flags=256 2(3926) end of header reached, state=9 2(3926) DEBUG: get_hdr_field: <To> [40]; uri=[sip:8580002@191.0.0.2] 2(3926) DEBUG: to body ["8580002"<sip:8580002@191.0.0.2> ] 2(3926) get_hdr_field: cseq <CSeq>: <1> <REGISTER> 2(3926) DEBUG: get_hdr_body : content_length=0 2(3926) found end of header 2(3926) find_first_route: No Route headers found 2(3926) loose_route: There is no Route HF 2(3926) is_local(): Realm '191.0.0.2' is not local 2(3926) DEBUG: add_param: tag=f7391c78 2(3926) end of header reached, state=29 2(3926) is_local(): Realm '191.0.0.2' is not local 2(3926) parse_headers: flags=-1 2(3926) check_via_address(1910.0.2, 192.168.1.20, 0) 2(3926) DEBUG:destroy_avp_list: destroying list (nil) 2(3926) receive_msg: cleaning up Ip address 192.168.1.20 is SIP client (CounterPath X-Lite) and 191.0.0.2 is SER's. And I added "191.0.0.2" ip address for "trusted" table (MySQL database). Someone can help me? Thanks --------- Aihara sahria.hao(a)gmail.com
