[Freeswitch-dev] mod_httapi
by Karl Seacrest 01 Feb '12

01 Feb '12

Hello, I will like to know how i can use Pre-Answer feature using the mod_httapi. This is useful to perform operations like playing playing custom caller tunes or validate the callers phone number from database before the call is answered. How can i achieve this using the FreeSWITCH mod_httapi? Also does mod_httapi send caller information (Caller ID, etc) along when requesting a URI? Regards Karl C.

[Freeswitch-dev] Absolute conditions are not changing the proceed variable... (mod_dialplan_xml.c)
by Rafael Vargas 01 Feb '12

01 Feb '12

Hi, I've noticed that when I have an extension containing only an absolute condition, the proceed variable in mod_dialplan_xml.c:parse_exten(...) is not changed and the next extension is also executed, thus ignoring the first extension's "continue" attribute, which was set to "false". I'm referring to this code: (mod_dialplan.c:221 in today's GIT) ... } else if (time_match == -1) { switch_log_printf(SWITCH_CHANNEL_SESSION_LOG_CLEAN(session), SWITCH_LOG_DEBUG, "Dialplan: %s Absolute Condition [%s] match=%s\n", switch_channel_get_name(channel), exten_name, all ? "all" : "any"); pass++; if (!all && !xor) break; } else if (time_match == 1) { ... Shouldn't this set the proceed variable to 1, just like the regex condition a few lines above (line 208 in today's GIT)? I just made a quick test and it worked as (I) expected. What I'm proposing is to change the code above to the following: ... } else if (time_match == -1) { switch_log_printf(SWITCH_CHANNEL_SESSION_LOG_CLEAN(session), SWITCH_LOG_DEBUG, "Dialplan: %s Absolute Condition [%s] match=%s\n", switch_channel_get_name(channel), exten_name, all ? "all" : "any"); proceed = 1; pass++; if (!all && !xor) break; } else if (time_match == 1) { ... Sorry if this was already discussed, I've searched this list and the users list to no avail...

[Freeswitch-dev] get_trillium_val() loop termination
by Juraj Fabo 01 Feb '12

01 Feb '12

Hi I'm using freetdm from git downloaded on 30.1.2012. On windows I had no problems, but on sles 11 sp1 64bit call setup message was missing caller and called information elements. I've tracked down the problem to file src/ftmod/ftmod_sangoma_isdn/ftmod_sangoma_isdn_support.c, into function get_trillium_val() Particularly, when get_trillium_val(ton_codes, 0, IN_TON_UNK) is called, 0xe6 is returned (which is from the nsf_spec_codes[] table) I think the loop should have some strict terminate condition but not sure about the write intention. My workaround to be able to continue development is following diff -urN src/ftmod/ftmod_sangoma_isdn/ftmod_sangoma_isdn_support.c src/ftmod/ftmod_sangoma_isdn/ftmod_sangoma_isdn_support_mod.c --- src/ftmod/ftmod_sangoma_isdn/ftmod_sangoma_isdn_support.c 2012-02-01 14:02:30.000000000 +0000 +++ src/ftmod/ftmod_sangoma_isdn/ftmod_sangoma_isdn_support_mod.c 2012-02-01 14:02:08.000000000 +0000 @@ -106,10 +106,11 @@ static uint8_t get_trillium_val(ftdm2trillium_t *vals, uint8_t ftdm_val, uint8_t default_val) { ftdm2trillium_t *val = vals; - while(val++) { + while(val) { if (val->ftdm_val == ftdm_val) { return val->trillium_val; } + val++; } return default_val; } @@ -117,10 +118,11 @@ static uint8_t get_ftdm_val(ftdm2trillium_t *vals, uint8_t trillium_val, uint8_t default_val) { ftdm2trillium_t *val = vals; - while(val++) { + while(val) { if (val->trillium_val == trillium_val) { return val->ftdm_val; } + val++; } return default_val; } Is there some other way how to go around?

[Freeswitch-dev] switch_stun_random_string returns identical strings on two calls randomly
by Seven Du 01 Feb '12

01 Feb '12

Hi, I tried to replace the following function which I copied somewhere in msrp.c with switch_stun_random_string (http://docs.freeswitch.org/group__stun1.html#geb124530a232d65edc508afd1b9dd…) but I found sometimes switch_stun_random_string (http://docs.freeswitch.org/group__stun1.html#geb124530a232d65edc508afd1b9dd…) returns identical strings on two sequential calls, with the following function I never found, so I still use it. By looking the code I understand srand seed is time based so it's possible to return duplicate random string, but I found switch_stun_random_string (http://docs.freeswitch.org/group__stun1.html#geb124530a232d65edc508afd1b9dd…) used in some places other than stun, just curious would it cause problems? void random_string(char *buf, switch_size_t size) { long val[4]; int x; for (x = 0; x < 4; x++) val[x] = random(); snprintf(buf, size, "%08lx%08lx%08lx%08lx", val[0], val[1], val[2], val[3]); *(buf+size) = '\0'; } Thanks. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)
