mt_match avp behavior
by Juha Heinanen 05 Sep '14

05 Sep '14

looking at the code, i appears that mt_match does not initialize pv_values pv when it stores matched values thus keeping possible existing values from previous calls. is that intended behavior? readme uses word "store". -- juha

mtree README missing params
by Juha Heinanen 05 Sep '14

05 Sep '14

looks like 4.1 and master mtree README is missing these parameters: {"pv_dstid", STR_PARAM, &dstid_param.s}, {"pv_weight", STR_PARAM, &weight_param.s}, {"pv_count", STR_PARAM, &count_param.s}, i didn'd find in the code any use for the last. -- juha

has "defined" been documented somewhere?
by Juha Heinanen 05 Sep '14

05 Sep '14

defined($avp(foo)) can be used to test if avp $avp(foo) has been defined. i looked through kamailio wiki, but didn't find defined function documented anywhere. -- juha

ldap returning attributes list
by Virmantas Variakojis 05 Sep '14

05 Sep '14

Hi, I'm trying to fetch attribute list with kamailio ldap_search: ldap_search("ldap://agents/ou=Xxxxx,dc=xxxx,dc=yyyyyy,dc=zz?memberOf?sub?(sAMAccountName=$fU)"); ldap_result("memberOf/$avp(s:ldapmemberof1)"); xlog("L_INFO", "LDAP $fU memberOf = $avp(s:ldapmemberof1)"); if (ldap_result_next()) { xlog("L_INFO", "if loop ldap_result"); ldap_result("memberOf/$avp(s:ldapmemberof2)"); xlog("L_INFO", "LDAP $fU memberOf = $avp(s:ldapmemberof2)"); } There's must be seven returning attributes list of memberOf, but I can only retrieve only one of them (looks like last of seven). First xlog output log into my log file, but if loop didn't start. What I'm doing wrong?

Dispatcher algorithm 9 ignores weight=xx attribute
by Alejandro Recarey 05 Sep '14

05 Sep '14

Hi, I have a kamailio with the dispatcher module setup. I use: ds_select_dst("1", "9"); to load balance between 3 gateways. My database looks like this: id setid destination flags priority attrs 5 1 sip:1.1.1.1 0 0 weight=10 8 1 sip:1.1.1.2 0 0 weight=45 9 1 sip:1.1.1.3 0 0 weight=45 As I understand it, most of the calls should be split evenly between gateways 8 and 9, and some calls (around 10%) going to gateway 5. Well, gateway 8 gets 99% of the calls. I am using kamailio 4.1 and I really cannot understand why this is happening. Running ds_list shows me that all gateays and weights are correctly parsed into kamailio. This is the result of my ds_list: SET:: 1 URI:: sip:1.1.1.1 flags=AP priority=0 attrs=weight=10 URI:: sip:1.1.1.2 flags=AP priority=0 attrs=weight=45 URI:: sip:1.1.1.3 flags=AP priority=0 attrs=weight=45 I have tried changing the priority to 100, or to 1 in every gateway, and the result is still the same. I have tried adding ; after the weight parameter, the colon is gone in the ds_list once kamailio parses it. If, keeping the same database, I use ds_select_dst("1", "0") the calls are split evenly across all 3 gateways. This is great, but not what I want, but it at least proves that something is working. Is there anything else I can try? Thanks a lot for the help! Alex

OT: RTCP logging
by Daniel Tryba 04 Sep '14

04 Sep '14

Slightly offtopic, but for QA reasons I'm interested in logging RTCP reports from peers that send them. It looks like rtpproxy-ng might be used to do this (I'm already using rtpproxy anyway). Is someone already doing this and willing to share some pointers?

Redirect server vs CANCEL
by Mihaly Zachar 04 Sep '14

04 Sep '14

Hi Gents, We have created a small redirect server using the Lua API to get the destinations. Lets say that it takes some time while the script generates the answer, during this time we got a CANCEL. How we can handle this properly ? As far as I could see the TM module always sends back the answer (302) and after that I get the "CANCEL" in my script. Here is my config: http://pastebin.com/7PyKBJyD Here is my test Lua script: http://pastebin.com/6VXn5y8m Could you please help me what is the best way to handle the CANCEL ? Is it possible to do it properly ? Thanks, Misi
