Hello, as discussed during our devel meeting, next major release 3.1 is scheduled for this autumn. Therefore the freezing should happen soon. Would be 2 weeks from now enough for everyone to push planned new features to repo? Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com/

Simple Least Cost Routing NPA-NXX?

by JR Richardson

Hi All, I'm in the lab with sip router 3.0 mocking up some trunk-group prefix routing with PDT and load balancing with Dispatcher. This is working great and as expected. I would like to incorporate some sort of LCR matching on NPA-NXX but I'm having some difficulty. The PDT module automatically strips the prefix so for trunk group routing it works great but really can't be used for matching NPA-NXX. The Carrierroute module is pretty nice and works as expected but the issue I'm having, it appears that I have to have a NPA-NXX entry for each domain gateway I want to send calls to. For instance if I have 3 gateways in domain 1, then I would need the same NPA-NXX record entry in the database for each gateway. The database entries would be [NPA-NXX] x [Number of Gateways] per domain. So having 100K routes would mean having 300K records. Am I looking at this correctly? This is really what it seems like to me but logically I would think this should not be the case? I really like the Dispatcher polling functions to actively know what gateways are on-line and off-line plus the different distribution algorithms to choose from. So it makes sense to me to implement a pseudo PDT/Distpacher scenario as an LCR but with PDT stripping the prefix, that can not be done. Is there another mechanism whereby I can dip the database looking for the NPA-NXX, extract the domain group and send that to the Dispatcher function, without stripping the prefix? Or can a PDT module parameter be added to not strip the prefix. But I'm not sure this will work, can the PDT module hold in memory a few hundred thousand records? Thanks.

Dispatcher: ds_select_domain(set, alg) with a pseudo variable.

by Geoffrey Mina

How difficult would it be to make ds_select_domain(set, alg) accept a pseudo variable for the "set" argument? I would like to map the $rU to a specific dispatcher set via a database table. I suppose i could just hard code three or four sets with a conditional if() statement, but I would prefer to make it a little more dyanimc. Correct me if I am wrong in my assumption that ds_select_domain() doesn't accept pseudo variables. Thanks.

Fwd: Re: Fwd: Re: Kamailio and NAPTR lookup with TLS

by Matteo Campana

Hi Daniel, I have followed your instruction (I'm using kamailio 1.5) and before the t_relay("0x05") statement I've setted: $du="sip:" + $rd + ";transport=tls"; but I get the following mesasge: Jul 14 15:17:55 OVSIPP /usr/local/sbin/kamailio[7790] Request leaving server, *D_-URI='sip:garr.it;transport=tls'_* - M=INVITE RURI=sip:xxx@garr.it F=sip:yyyyy@sip.mydomqin.it:5066 T=sip:123456789@sip.mydomain.it:5066 Jul 14 15:17:55 OVSIPP /usr/local/sbin/kamailio[7790]: CRITICAL:core:mk_proxy: could not resolve hostname: "garr.it" Jul 14 15:17:55 OVSIPP /usr/local/sbin/kamailio[7790]: ERROR:tm:uri2proxy: bad host name in URI <sip:garr.it;transport=tls> Jul 14 15:17:55 OVSIPP /usr/local/sbin/kamailio[7790]: ERROR:tm:t_forward_nonack: failure to add branches Therefore I would like to use information about TLS connection (tls port?) got from NAPTR record.
