[Serusers] INVITE transaction timer vs. 'Proceeding' timer

by Arek Bekiersz

Hello, This time I've got a question :) I think it will be useful for everybody. I have discussion with SIP device manufacturer about expiration time of call attempt. When call is made from UA it sends INVITE with "Expires: 65". It is controlled by device's timer setting "ring_time_limit". This timer can be set to anything between 10 and 600 seconds, we set it to 65 seconds. Fine. However at the same time it starts a special timer, say "max_response_time_invite". It can be set to anything between 8 and 20 seconds. We set it to 20 sec. Fine so far. CASE 1: Imagine we call from UA to PSTN number, using one of VoIP->PSTN providers. We have more than one provider, so we setup SER with "fr_timer" value of, let's say 25 seconds and "fr_inv_timer" of 60. We prepare failure routes in case when those timers hits in PSTN call. When "fr_timer" hits, we simply reroute to another gateway. Great. SER forwards INVITE from UA to remote PSTN gateway and at the same time sends back "100 Trying" to UA. Fine. Imagine now that it is busy-hour and it takes PSTN provider 21 seconds to send back "180 Ringing" (or "183 Session Progress") and after 8 seconds more remote callee picks up ("200 OK"). Unfortunately device wil send CANCEL to SER, because it hasn't received "180 Ringing" or "183 Session Progress" within the "max_response_time_invite" setting of 20 seconds. It only received "100 Trying" at the beginning. This ruined any failure route attempts from SER, as call failed. CASE 2: Imagine now a second call. This time PSTN provider send "183 Session Progress" after 14 seconds and remote callee picked up after further 15 seconds. This time everything went good. UA did not hit "max_response_time_invite" timer - it waited patiently for whole 29 seconds for remote callee to pick up. I think that when UA receives provisional response (like "100 Trying") from SER it should stop timer "max_response_time_invite" and use 'ring_time_limit'. What device does now, it uses: * "max_response_time_invite" when "100 Trying" received * "ring_time_limit" when "180 Ringing" or "183 Session Progress" received I haven't really found explanation of this in RFC3261. When you look at state machine on page 128, it is not explicitly said which timer controls behaviour of UA when in "Proceeding" state ("Proceeding" is entered oin receipt of ANY provisional response). QUESTION 1: what timer controls behaviour of UA when in "Proceeding" state? Especially regarding timeout. Is this still the 'timer B' started at the beginning of INVITE transaction? If it is 'timer B', why UA is CANCELing transaction after 20 seconds, if it informed by "Expires: 65" field in INVITE that it set 'timer B' to 65 seconds. QUESTION 2: What should I propose to manufacturer for maximum value for "max_response_time_invite"? Something like 120 seconds ? -- Thanks, Arek Bekiersz

RE: [Serusers] re : presence module with ser

by Yeung OnTai-q16645

Hi I'd like to use PA, XCAP with eyeBeam. Are you talking about the "ser-0.10.99-dev30-tm-timers-pa-3", I've downloaded the tar file and tried "make install". It seems like presence works fine, XCAP is also working(except RLS)... About the RLS, do I need to create a directory in "<xcap-root>/rls-services/global/index" where all the XML (for RLS) files are stored? How can I configure the eyeBeam accordingly? By default it's configured as "subscribe to contact list : $username$-list@$domain$". It seems like SER does not consider it as a list, it only considers it just another URI. Did I do something wrong? Or do I need to change anything in SER?

Try the version from http://ftp.iptel.org/pub/ser/presence That one should be relatively easy to build. Note that the XCAP server is not included.

Re: [Serusers] Error 599 : Message too big

by Akeru Ikena

OK, after some investigations here are my findings. I post them here so if some one get the same error he might get hints. It seems if the the other end of the call has his soft phone closed, this error is returned. I tried to increase the max size to 4096 and now I get the "Too many hops" error. Which means, the message is forwarded way too much time, beeing increased over the 2048 limit. Now, why do I get a route loop when a user is offline...I suspect this "...if (uri==myself) {..." of beeing the culprit. I added various alias to the proxy ip adress, to the proxy name and even the domain name bu nothing worked out. Any ideas ?

[Serusers] Can anyone define the 'flags' column in the location database?

by Leo Papadopoulos

Dear SER users, I cannot get any information on the column definition of the 'location' table. However, all I really need is the definition of the 'flags' column. I know if you set flags to 128 you insert a permanent entry into the location table, but I cannot figure out what the rest of the flags are for. Can anyone help? I have searched: - seruser archives - location module readme file - onsip website Leo Papadopoulos Web site: www.telecomCTO.com

[Serusers] handle_publish crashes in PA

by sip

Okay... I'll admit, this isn't the most recent PA module, but I thought someone might have a hint nonetheless. I'm running SER 0.9.6. I do NOT wish to upgrade to the somewhat haphazard presence snapshot as it's not entirely in stable/usable condition yet. I was, however, under the impression that simple PUBLISH/SUBSCRIBE methods would work okay on this version of the module. Am I mistaken? Usual stuff in the ser.cfg if(method=="SUBSCRIBE") { if(!t_newtran()) { log(1, "SUBSCRIBE newtran error\n"); sl_reply_error(); }; handle_subscription("registrar"); break; }; if(method=="PUBLISH") { if(!t_newtran()) { log(1, "PUBLISH newtran error\n"); sl_reply_error(); }; handle_publish("registrar"); break; }; When my Snom phone sends a publish, it looks like this: U 66.112.115.10:2057 -> 66.112.115.34:5060 PUBLISH sip:11019552444@my.domain.com:5060 SIP/2.0. Via: SIP/2.0/UDP 66.112.115.10:2057;branch=z9hG4bK-nc00a965o8y5;rport. From: "Death" <sip:11019552444@my.domain.com:5060>;tag=o6bezw24ge. To: "Death" <sip:11019552444@my.domain.com:5060>. Call-ID: 3c267063afc8-19wbm3ssr4y3@snom190. CSeq: 1 PUBLISH. Max-Forwards: 70. Event: proxy-config. Content-Type: application/text. Content-Length: 0. . It sends this (with slightly different From: tags) 9 times and then ser coredumps without a word to the log. Any ideas? Give up presence for now and just tell my users to get over it? :) N.

[Users] tls_domain section for outoing TLS connections

by Klaus Darilion

Hi! Reading the TLS docs I understand that using the tls_domain section, I can specify different certificates and CAs which will be used according to the socket on which the incoming TLS request is received. But is there also a way to use the "TLS domains" also for outgoing TLS connections? If yes, how do I trigger using a certain "TLS domain" for outgoing TLS connections? regards klaus
