Using t_suspend()/t_continue() multiple times on the same transaction
by Peter Dunkley 02 Jul '14

02 Jul '14

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 19 Feb '14

19 Feb '14

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. The change in tm module fixes a bug: if uac_replace_to() was called, the URI was not changed accordingly in Cancel. --- modules/tm/t_cancel.c | 5 +- modules_k/dialog/dialog.c | 2 + modules_k/dialog/dlg_load.h | 6 + modules_k/uac/README | 111 +++++++++++----- modules_k/uac/doc/uac_admin.xml | 68 +++++++++- modules_k/uac/replace.c | 292 ++++++++++++++++++++++++++++++--------- modules_k/uac/uac.c | 17 ++- 7 files changed, 393 insertions(+), 108 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=0f7…

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!

™ delete_timer obsolete?
by Olle E. Johansson 14 Oct '12

14 Oct '12

According to the 3.3 docs, this function in the ™ module is no longer needed. Is this correct? If so, should someone remove it? Hmm. All mentions of ™ gets automatically converted to a trademark sign in my mailer. I mean the T M Module :-) /O -------- 1.4.6. delete_timer (integer) Time after which a to-be-deleted transaction currently ref-ed by a process will be tried to be deleted again (in milliseconds). Note: this parameter is obsolete for ser 2.1 (in 2.1 the transaction is deleted the moment it's not referenced anymore). Default value is 200 milliseconds. Example 6. Set delete_timer parameter ... modparam("tm", "delete_timer", 100) ...

Bug in sdp parser
by Vicente Hernando 08 Oct '12

08 Oct '12

Hello, if we have a SDP content like this one: v=0 o=alice 2890844526 2890844527 IN IP4 host.example.com s= c=IN IP4 session.foo.org t=0 0 m=audio 49170 RTP/AVP 97 c=IN IP4 stream.bar.org a=rtpmap:97 iLBC/8000 m=audio 49170 RTP/AVP 97 a=rtpmap:97 iLBC/8000 m=audio 49170 RTP/AVP 97 c=IN IP4 bar.baz.net a=rtpmap:97 iLBC/8000 When parsing this function three streams are created: first one will have ip_addr string equal to "stream.bar.org" second one: "stream.bar.org" <-- Wrong! it is using same as first one, instead using session default third one: "bar.baz.net" Attached patch solves it. Kind regards, Vicente.
