Using t_suspend()/t_continue() multiple times on the same transaction

by Peter Dunkley

Hi, I am trying to use t_suspend()/t_continue() multiple times on the same transaction. Calling t_suspend() more than once works, but the second time I call t_continue() the transaction is killed and a 500 response is sent. It is the "if (branch == t->nr_of_outgoings)" check from the code fragment below (from t_suspend.c:t_continue()) that results in the transaction being killed - you can see the debug/error line I added to determine this in the fragment. Is using t_suspend()/t_continue() multiple times something that should work? Thanks, Peter if (t->uas.status < 200) { /* No final reply has been sent yet. * Check whether or not there is any pending branch. */ for ( branch = 0; branch < t->nr_of_outgoings; branch++ ) { if ((t->uac[branch].request.buffer != NULL) && (t->uac[branch].last_received < 200) ) break; } if (branch == t->nr_of_outgoings) { /* There is not any open branch so there is * no chance that a final response will be received. */ ret = 0; LM_ERR("branch == t->nr_of_outgoings\n"); goto kill_trans; } } -- Peter Dunkley Technical Director Crocodile RCS Ltd

default config: do loose_route() for in-dialog NOTIFY as per new RFC 6665

by Iñaki Baz Castillo

Hi, the new RFC 6665 mandates that the subscription dialog is made *after* the first NOTIFY from the UAS (rather than after the 200 to the initial SUBSCRIBE). This means that the UAC MUST take the route set from the *first* received NOTIFY (instead of taking it from the 200 to the initial SUBSCRIBE). Therefore a proxy compliant with RFC 6665 MUST always add RR to in-dialog NOTIFY requests and thus, I propose that the default SR script file implements it. Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>

In this mode the URIs are stored as dialog variables.

dns resolver issue (RFC3263)

by MÉSZÁROS Mihály

Hi All, I am experiencing an issue when i try to contact xy(a)cisco.com. I found that kamailio/sip-router can't resolve by default resolving way a TCP + SRV records from domain cisco.com. e.g. cisco.com misi@alma:~$ host -t NAPTR cisco.com cisco.com has no NAPTR record misi@alma:~$ host -t SRV _sip._udp.cisco.com Host _sip._udp.cisco.com not found: 3(NXDOMAIN) misi@alma:~$ host -t SRV _sip._tcp.cisco.com _sip._tcp.cisco.com has SRV record 1 0 5060 vcsgw.cisco.com. misi@alma:~$ host -t SRV _sips._tcp.cisco.com _sips._tcp.cisco.com has SRV record 1 0 5061 vcsgw.cisco.com. I can't call xy(a)cisco.com because it does not exists an NAPTR record in domain cisco.com, and furthermore no SRV with udp. But it exists sip+tcp record and also exists an secure sip SRV, so sips+tcp record! I read rfc3263 I find kamailio dns resolver is not working as it should according RFC3263. http://tools.ietf.org/html/rfc3263 _If no NAPTR records are found, the client constructs SRV queries for those transport protocols it supports, and does a query for each._ So kamailio should query all (udp, tcp, tls, sctp whatever) protocols. Can anyone help/guide me to create a fix to this issue? My plan is to create a patch to kamailio resolver, to correct and behave according RFC3263. Any help or guidance appreciated! Thanks, Misi

git:master: New Option: "x" for automatic bridging between IPv4 and IPv6.

Based on the following assumption: "i" is the IPv4 interface and "e" is the IPv6 interface on the RTPProxy (tested with both RTPProxy and Sipwise's ngcp-mediaproxy-ng). Mechanism is as follows: - IP in SDP is IPv4: Do bridging "ie" - IP in SDP is IPv6: Do bridging "ei" Not a big deal, but makes the configuration much more easier. --- modules/rtpproxy/doc/rtpproxy.xml | 8 ++++++++ modules/rtpproxy/doc/rtpproxy_admin.xml | 7 +++++++ modules/rtpproxy/rtpproxy.c | 22 +++++++++++++++++++++- 3 files changed, 36 insertions(+), 1 deletions(-) diff --git a/modules/rtpproxy/doc/rtpproxy.xml b/modules/rtpproxy/doc/rtpproxy.xml index d5a15ee..741a4d9 100644 --- a/modules/rtpproxy/doc/rtpproxy.xml +++ b/modules/rtpproxy/doc/rtpproxy.xml @@ -57,6 +57,14 @@ <email>osas(a)voipembedded.com</email> </address> </editor> + <editor> + <firstname>Carsten</firstname> + <surname>Bock</surname> + <affiliation><orgname>ng-voice GmbH</orgname></affiliation> + <address> + <email>carsten(a)ng-voice.com</email> + </address> + </editor> </authorgroup> <copyright> <year>2003-2008</year> diff --git a/modules/rtpproxy/doc/rtpproxy_admin.xml b/modules/rtpproxy/doc/rtpproxy_admin.xml index a245d73..d6a9dc5 100644 --- a/modules/rtpproxy/doc/rtpproxy_admin.xml +++ b/modules/rtpproxy/doc/rtpproxy_admin.xml @@ -344,6 +344,13 @@ rtpproxy_offer(); the 'w' flag for clients behind NAT!
