strange acc behavior?
by Klaus Darilion 17 Sep '10

17 Sep '10

Hi! I use acc module with extra accounting. modparam("acc", "db_extra", "direction=$avp(direction)") I set $avp(direction) during request processing (in main request route). The value stored with INVITE and BYE is fine, but ACK requests do not have the assigned value, but the same value as the INVITE request. Is this by design? Is this a limitation of tm and AVPs? Thanks Klaus

Stripping variable amount of digits
by Iñaki Baz Castillo 16 Sep '10

16 Sep '10

Hi, I get a prefix string from a database and store it in $var(prefix). Such prefix can contain any number of digits (no fixed length). Now I must to check if the RURI username begins with that prefix and in that case strip it. I can get the first step (detect it) using pcre_match function: if pcre_match("$rU", "^$var(prefix)") { # Prefix match. But I cannot get the second part working (stripping it). I've tryed everything: - strip() is not valid as just allows an integer (no pv). - subst_user() doesn't accept pv: if subst_user("/^$var(prefix)(.*)$/\1/") Any ideas please? Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Doubd about Dialplan module
by rabs＠dimension-virtual.com 16 Sep '10

16 Sep '10

Hi all, I'm tryting to implement a E164 normalizer using the dialplan module, by now I have 3 simple rules: dpid priority matchop matchex matchlen subsex replaceex attributes 0 1 1 (00|\+)([1-9][0-9]+) 0 (00|\+)([1-9][0-9]+) \2 0 1 1 ([5-9][0-9]{8}) 0 ([5-9][0-9]{8}) 34\1 The first rule 'it's supposed' to remove + or 00 from full qualified E164 numbers, the seccond rule 'should' add 34 as prefix to all 'valid' spanish numbers, they was running on some little test I did, but when try to put them on pre-production enviroment I get strage results. I call dp_translate as dp_translate("0","$rU/$rU"); And this what I get : Input RURI Output RURI 900XXXXXX(a)dom.tld XXXXXX(a)dom.tld And the quetion is why?, are my match rules wrong? why subex and matchex must be the same? Best regards. -- Raul Alexis Betancor Santana Dimension Virtual S.L.

string manipulation from db
by anthony thomas 16 Sep '10

16 Sep '10

Hello list, I am afraid I am asking something stupid but I cannot find a way to do this cleanly, so here it goes.... I am retrieving values from a db using either carrierroute or mtree modules to send a 302 to my softswitch. It expects the message as: SIP/2.0 302 Moved Temporarily Via: SIP/2.0/UDP 134.111.48.66:5060;branch=zgfdgdfgf2491b5437 Contact: <sip:989897@X.X.X.X;rg=4003>;q=0.2 Contact: <sip:989897@X.X.X.X:rg=321>;q=0.8 To: <sip:989897@X.X.X.X:5066>;tag=1 ..... Where the important things are the rg: those are the trunks in the SS) and the q (probability) and there can be multiple rgs for the same prefix (2 in this example) My idea was to keep in the db something like this: Prefix:98 Route:4003,0.2|321,0.8 And then inject those values in the contact header, but I am having a hard time finding the right way to do it. Is there any way to do it without calling the perl module? Many thanks, A

About avp's, var's, null, 0 and empty string
by Iñaki Baz Castillo 16 Sep '10

16 Sep '10

Hi, I would like to summarize how $avp's and $var's handle the null value, 0 and empty string. For this I've writen the following test I've checked in Kamailio 1.5.4: -------------------------- $var(null) = null; $avp(s:null) = null; $var(empty) = ""; $avp(s:empty) = ""; xlog("var(null): '$var(null)'\n"); if $var(null) == null xlog("*** if var(null) == null \n"); if $var(null) xlog("*** if var(null) \n"); if $var(null) != null xlog("*** if var(null) != null \n"); if ! $var(null) xlog("*** if ! var(null) \n"); if $var(null) == '' xlog("*** if var(null) == '' \n"); if $var(null) == 0 xlog("*** if var(null) == 0 \n"); xlog("\n"); xlog("avp(s:null): '$avp(s:null)'\n"); if $avp(s:null) == null xlog("*** if avp(s:null) == null \n"); if $avp(s:null) xlog("*** if avp(s:null) \n"); if $avp(s:null) != null xlog("*** if avp(s:null) != null \n"); if ! $avp(s:null) xlog("*** if ! avp(s:null) \n"); if $avp(s:null) == '' xlog("*** if avp(s:null) == '' \n"); if $avp(s:null) == 0 xlog("*** if avp(s:null) == 0 \n"); xlog("\n"); xlog("var(empty): '$var(empty)'\n"); if $var(empty) == null xlog("*** if var(empty) == null \n"); if $var(empty) xlog("*** if var(empty) \n"); if $var(empty) != null xlog("*** if var(empty) != null \n"); if ! $var(empty) xlog("*** if ! var(empty) \n"); if $var(empty) == '' xlog("*** if var(empty) == '' \n"); if $var(empty)== 0 xlog("*** if var(empty) == 0 \n"); xlog("\n"); xlog("avp(s:empty): '$avp(s:empty)' \n"); if $avp(s:empty) == null xlog("*** if avp(s:empty) == null \n"); if $avp(s:empty) xlog("*** if avp(s:empty) \n"); if $avp(s:empty) != null xlog("*** if avp(s:empty) != null \n"); if ! $avp(s:empty) xlog("*** if ! avp(s:empty) \n"); if $avp(s:empty) == '' xlog("*** if avp(s:empty) == '' \n"); if $avp(s:empty) == 0 xlog("*** if avp(s:empty) == 0 \n"); ------------------------- The result is: ------------------------- var(null): '0' *** if var(null) != null *** if ! var(null) *** if var(null) == 0 avp(s:null): '<null>' *** if avp(s:null) == null *** if ! avp(s:null) var(empty): '' *** if var(empty) != null *** if ! var(empty) *** if var(empty) == '' CRITICAL:core:comp_scriptvar: invalid operation 20/3/4!! WARNING:core:do_action: error in expression (l=356) avp(s:empty): '' *** if avp(s:empty) != null *** if ! avp(s:empty) *** if avp(s:empty) == '' CRITICAL:core:comp_scriptvar: invalid operation 20/3/4!! WARNING:core:do_action: error in expression (l=372) ------------------------- Conclusions: - $var cannot store null value. If so it converts it to 0. - When cheking "if $avp(...) {" the result is false in case the content of the $avp is null, 0 or an empty string. - When cheking "if $var(...) {" the result is false in case the content of the $var is 0 or an empty string. Any thoughts on this? Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Calling force_rtp_proxy twice
by Ernest Mavrel 15 Sep '10

15 Sep '10

Hi I have problem with force_rtp_proxy. Kamailio server have multi network interfaces. I have two PSTN GW-s. And If is something wrong with first one, the call is send to the second via PSTN failover route. When I send call to the first GW I'm calling force_rtp_proxy("oc","10.10.10.1"); But the first GW respond with 404 Not found, so I send INVITE to the second GW with calling force_rtp_proxy("oc","10.10.20.1"); In SDP I see double IP's : o=root 26366 26367 IN IP4 10.10.10.110.10.20.1 s=session c=IN IP4 10.10.10.110.10.20.1 How to resolve that? Thank you Ernest

pdb and carrier id zero in finnish LNP
by Mikko Lehto 14 Sep '10

14 Sep '10

Hi I am exploring the applicability of pdb module in finnish number portability scheme. Looks like carrier id 000 cannot be used as zero is already reserved for "the number could not be found" result in pdb protocol. (Queries seem to work after I changed MIN_PDB_CARRIERID in common.h to 0, but unfortunately that configuration just does not make sense.) Is there any way out of this other than using internally different value for carrier 0? I rather use correct ids if somehow possible to avoid mapping logic in routing script. Note about help text consistency: When going through pdbt.c there is this comment above import_csv function: /* Read a csv list from the given file and build a dtree structure. Format of lines in csv file: "<number prefix>;<carrier id>". Format of carrier id: "D[0-9][0-9][0-9]". Returns the number of lines imported or -1 on error. */ Isn't the third line incorrect? Same thing also in help text output of pdbt -h. docs/data_format.txt mentions letter D only in front of carrier name file. What is the meaning of D anyway in this context? Here is my awk pipe contribution to scripts/get_carrier_names_finland.sh: curl -o - "http://www2.ficora.fi/numerointi/nure_numbering.asp?nums=tot&lang=en" | awk '/<tbody>/, /<\/tbody>/' | awk -F"</td" -v RS="</tr" '{ gsub(/.*>/,"",$1) gsub(/.*>/,"",$2); gsub(/ä/,"ä",$2); gsub(/Å/,"Å",$2); gsub(/ö/,"ö",$2); if ( $2 != "") { printf "D%.3d %s\n",$1,$2 } }' -- Mikko Lehto
