app_python rewrite_ruri - BUG: do_action bad set*()
by V Tone 15 Feb '13

15 Feb '13

Hi, I'm having problems getting started with the app_python module. I'm getting the following in the logs: 5(8890) : <core> [action.c:785]: BUG: do_action: bad set*() type 14 5(8890) ERROR: <core> [action.c:1568]: run action error at: :0 5(8890) ERROR: app_python [python_msgobj.c:115]: Error in do_action 5(8890) ERROR: app_python [python_support.c:38]: python_exec2: Unhandled exception in the Python code: 5(8890) ERROR: app_python [python_support.c:78]: RuntimeError: Error in do_action My Python module is very basic: class Router(object): def child_init(self, child_id): return 0 def route(self, msg): msg.rewrite_ruri('sip:1000@1.2.3.4:5060') return 0 def mod_init(): instance = Router() return instance I've tested this in Kamailio 3.2 and 3.3. Can someone point me to what I'm doing wrong? Many thanks in advance, vtone

siptrace/sipcapture and MSRP
by Peter Dunkley 15 Feb '13

15 Feb '13

Hello, Is there any reason why I couldn't use the existing siptrace() function in event_route[msrp:frame-in] to relay all MSRP messages to a SIP Capture node? Will the SIP Capture node handle receiving these messages? What will end up in the WebHomer display in these cases? Regards, Peter

Dialog is not cleaned up after failed calls and BYEs.
by Aft nix 15 Feb '13

15 Feb '13

Hi, I'm trying to limit concurrent calls through kamailio using following script: #!ifdef WITH_CALL_LIMIT if (is_method("INVITE")) { dlg_manage(); $var(100) = 0; get_profile_size("callquota", "$fd", "$var(100)"); if ($var(100) >= 100 ) { xdbg("DEBUG: Simultaneous calls limit reached"); sl_send_reply("503","Simultaneous calls limit reached"); exit; } set_dlg_profile("callquota","$fd"); } #!endif But the dialogs are not cleaned up after the call ends or a failed call happens. For example after two failed calls : [root@new tls]# kamctl fifo profile_get_size callquota profile:: name=callquota value= count=4 and the dialog list : [root@new tls]# kamctl fifo dlg_list dialog:: hash=896:11654 state:: 1 ref_count:: 1 timestart:: 0 timeout:: 0 callid:: iSGRqQR0C4suBpQD0rHAEgV42vw0Sbpe from_uri:: sip:123@205.164.40.150 from_tag:: d8x2LDBptN9FRJWtqFTj4DIpuQlKq.KN caller_contact:: sip:123@180.149.7.45:33852;ob caller_cseq:: 11755 caller_route_set:: caller_bind_addr:: udp:185.8.105.70:9547 callee_bind_addr:: to_uri:: sip:8801684077496@205.164.40.150 to_tag:: callee_contact:: callee_cseq:: callee_route_set:: dialog:: hash=896:11655 state:: 1 ref_count:: 1 timestart:: 0 timeout:: 0 callid:: iSGRqQR0C4suBpQD0rHAEgV42vw0Sbpe from_uri:: sip:123@205.164.40.150 from_tag:: d8x2LDBptN9FRJWtqFTj4DIpuQlKq.KN caller_contact:: sip:123@180.149.7.45:33852;ob caller_cseq:: 11755 caller_route_set:: caller_bind_addr:: udp:185.8.105.70:9547 callee_bind_addr:: to_uri:: sip:8801684077496@205.164.40.150 to_tag:: callee_contact:: callee_cseq:: callee_route_set:: dialog:: hash=896:11657 state:: 1 ref_count:: 1 timestart:: 0 timeout:: 0 callid:: iSGRqQR0C4suBpQD0rHAEgV42vw0Sbpe from_uri:: sip:123@205.164.40.150 from_tag:: d8x2LDBptN9FRJWtqFTj4DIpuQlKq.KN caller_contact:: sip:123@180.149.7.45:33852;ob caller_cseq:: 11756 caller_route_set:: caller_bind_addr:: udp:185.8.105.70:9547 callee_bind_addr:: to_uri:: sip:8801684077496@205.164.40.150 to_tag:: callee_contact:: callee_cseq:: callee_route_set:: dialog:: hash=1532:8089 state:: 1 ref_count:: 1 timestart:: 0 timeout:: 0 callid:: povqQaC.sRhKvmUaLzzR83bRXxouoNy8 from_uri:: sip:123@205.164.40.150 from_tag:: qXQll3QXrff.t27FHY2hucPfJ7K8Pfrs caller_contact:: sip:123@180.149.7.45:33852;ob caller_cseq:: 9232 caller_route_set:: caller_bind_addr:: udp:185.8.105.70:9547 callee_bind_addr:: to_uri:: sip:8801684077496@205.164.40.150 to_tag:: callee_contact:: callee_cseq:: callee_route_set:: You can see there are multiple entries.

Registration and TCP connection
by Krishna Kurapati 15 Feb '13

15 Feb '13

Hi, When client connects to server over TCP/TLS and REGISTERs two things that can happen. 1. Client can disconnect the connection when the App is killed abruptly and the client did not get a chance to send unregiter. 2. CRLF KA did not arrive due to network failures in the middle. Is there a way to remove contact from usrloc table. This can spare server from trying to send message to a client who is no longer connected to the server. It would be ideal if this can be done automatically with a module param in tcp or registrar. Any suggestion on how to tie TCP connection with usrloc? Thanks Krish Kura

kamailio - simple presence over port 5061
by David Thomson 15 Feb '13

15 Feb '13

I was wondering if simple presence can work over port 5061 or if it always goes over 5060. my client (jitsi) is configured to work over port 5061, xcap is configured to work over port 5061 but I am still seeing some messages flowing over port 5060. any ideas as to what is going on? ttyl,Dave

[Fwd: Re: Deleting the expired contacts using the Rtimer module]
by kiran bhosale 15 Feb '13

15 Feb '13

he array values that we are modifying and the function that we call periodically are from our module . to exemplify i have put the code below .our requirement is that we want to delete the expired contacts without relying on usrloc module as "we have not used any DB for contact storage" but developed our own module for storing them in a file.even we had installed the SIGALRM handler in our module for decrementing the contacts but the values of array (that stores the expires) elements were zero. we thought of workaround to store the expires values to file and decrement them periodically. but frequent I/O is very consuming. whats the solution for deleting the expired contacts . #define DB_PATH "/usr/local/etc/kamailio/dbtext/syntel" #define DB_PATH1 "/usr/local/etc/kamailio/dbtext/temp" #define MAX_BUFFER 128 #define MAX_USERS 128 typedef struct { int max_bindings; int syntel_index; int expires[8]; char ip_addr[8][16]; } Syntel_users; Syntel_users syntel_database[16]={{0}}; //this is function used for storing the contacts int write_to_file (char *uri, char *user, int locator,int expires) { int Retval = 0; int fd; int bytes; char ip[13]; strncpy (ip, &uri[9], 12); ip[12] = '\0'; fd = open (DB_PATH, O_CREAT | O_RDWR | O_APPEND, 0777); if (syntel_database[locator].max_bindings < 8) { strcpy (syntel_database[locator].ip_addr[syntel_database[locator].max_bindings], uri); syntel_database[locator].expires[syntel_database[locator].max_bindings]=expires; syntel_database[locator].max_bindings++; bytes = write (fd, uri, strlen (uri)); Retval = 1; } return Retval; } //AND THIS IS FUNCTION WE CALL FROM kamailio.conf WITH RTIMER MODULE AFTER INTERVAL OF 1 SECOND. int syntel_delete (void) { int counter; int j; for (counter = 0; counter < 16; counter++) { for (j = 0; j < syntel_database[counter].max_bindings; j++) { if(syntel_database[counter].expires[j]<=0) { memset(syntel_database[counter].ip_addr[j],0,strlen(syntel_database[counter].ip_addr[j])); syntel_database[counter].max_bindings--; } else syntel_database[counter].expires[j]--; } } return 0; } BUT WHAT THIS FUNCTION GETS IS ZERO VALUES FOR EXPIRES AND NOT MODIFIED IN SYNTEL_WRITE_TO_FILE HOW TO DECREMENT THESE VALUES PERIODICALLY THEN ??

Hello all, Is there any way to rewrite "tu" in CANCEL message in 3.2.1? We use remove_hf / insert_hf for INVITE's "tu" modification before t_relay. It works fine, but it doesn't work for CANCEL (INVITE re-parsing is disabled). Ths,
