Hi All. I thought I read something a while ago about using avpops to dymanically change the INVITE timer - but I can't seem to find that thread. Can anyone tell me if this is possible? I'd like to have a shorter INVITE timer for SIP->SIP calls and a longer INVITE timer for SIP->PSTN calls. We see some 408 replies because a SIP phone is dialing a cell phone and get transfered to the voicemail of the cell phone user, but to prevent the 408 due to a slow voicemail system we have our INVITE timer currently set at 40 seconds which is rather annoying for SIP->SIP calls. I'm using -dev-21 Regards, Paul __________________________________ Do you Yahoo!? Yahoo! Mail - Easier than ever with enhanced search. Learn more. http://info.mail.yahoo.com/mail_250

Hi Paul, you can control final_response_timer and final_response_invite_timer via avps. Set in TM fr_inv_avp / fr_inv_timer_avp parameters with some AVP string names and use AVPOPS to give values to these AVPS: modparam("tm","fr_inv_timer_avp","inv_timeout") .... avp_write("20","inv_timeout"); # set timeout to 20 sec t_relay(); .....

Thanks, however I must be doing something wrong because the avp_write() doesn't seem to have any effect on the INVITE timer timeout. My ser.cfg looks like this: # ------------- tm parameters modparam("tm", "fr_timer", 15) modparam("tm", "fr_inv_timer", 22) modparam("tm", "wt_timer", 5) modparam("tm", "fr_inv_timer_avp", "inv_timeout") route { # sanity checks, record route, alias lookup, etc, etc if (!lookup("location")) { if (uri=~"^sip:[0-9]{10}@") { # Send to PSTN Gateway avp_write("45", "inv_timeout"); route(3); break; } sl_send_reply("404", "User Not Found"); break; }; # normal SIP->SIP routing with default fr_inv_timer # set to 22 seconds with mod_param() above route(2); } Shouldn't this do the trick?

Hello, I want to know if it is possible to load the timeout value for DB with something like: modparam("avpops","avp_aliases","inv_timeout=i:1234") modparam("tm", "fr_inv_timer_avp", "$inv_timeout") ... avp_db_load("$ruri", "$inv_timeout/forwardingDB") Thanks Laurent -----Original Message----- From: serusers-bounces(a)iptel.org [mailto:serusers-bounces@lists.iptel.org] On Behalf Of Java Rockx Sent: vendredi, 3. décembre 2004 15:27 To: marian.dumitru(a)voice-sistem.ro Cc: ser users Subject: Re: [Serusers] Dynamic Invite Timer w/AVPOPS Thanks, however I must be doing something wrong because the avp_write() doesn't seem to have any effect on the INVITE timer timeout.

Hi Laurent, Yes, you can do so. Unfortunately the "fr_inv_timer_avp" parameter doesn't supports AVP aliases, but only raw names - not even IDs :-(. So, do something like this: modparam("tm", "fr_inv_timer_avp", "inv_timeout") ... avp_db_load("$ruri", "inv_timeout/forwardingDB") ... Since the TM expects for "fr_inv_timer_avp" an string name AVP with string value, you have to set type=0 in AVP database (see http://www.voice-system.ro/docs/avpops/ar01s04.html for more details). I would take the opportunity to ask if it wouldn't be better to use number values for this AVPs ("fr_inv_timer_avp" and "fr_timer_avp") instead of strings - it will save a lot of extra conversions.

Yes, it would be better and it is on my todo list after the new release. Jan. On 03-12 20:03, Marian Dumitru wrote:

Hi Paul, The script looks ok. The problem is in other part; it took my some time to trace it - there is a bug in TM in setting the "fr_inv_timer_avp" parameter. Because of this, the AVP was not found and default value was applied for timeout. Please find attach a patch to fix the problem. Best regards, Marian Java Rockx wrote:

Hello, Please create an issue in http://bugs.sip-router.org or send a patch to serdev(a)lists.iptel.org if you discover a bug (I have fixed this one already in CVS). Thanks. Jan. On 03-12 19:54, Marian Dumitru wrote:

Hi Paul, you can optimized a little bit by forcing the avp value directly as number (to avoid conversions on runtime, for each invite). replace avp_write("45", "inv_timeout"); with avp_write("i:45", "inv_timeout"); Best regards, Marian Java Rockx wrote:
