by Yazid Hadj Said 30 May '08

30 May '08

Hi, please I want to know: If and How I can use variables in "regexp" . example: avp_subst("avp(s:var1)/$avp(s:var2)","/(.*)$avp(s:var3)(.*)/\1/") In this example, simply the "$avp(s:var3)" string is matched, not the $avp(s:var3)'s content. I am very need this function. Thanks in advance, Yazid

[OpenSER-Users] Correction in documentation of tm module(version 1.2.X)
by Ruchir Brahmbhatt 30 May '08

30 May '08

Hi, The following sentence in section 1.4.8. t_flush_flags() of tm module documentation(version 1.2.X) has several spelling mistakes. Incorrect Flush the flags from current request into the already created transaction. It make sens only in routing block if the trnasaction was created via t_newtran() and the flags have been altered since. Correct Flush the flags from current request into the already created transaction. It make sense only in routing block if the transaction was created via t_newtran() and the flags have been altered since. Thanks, Ruchir

[OpenSER-Users] Openser not processing requests at rate being sent to it
by Brian Peters 30 May '08

30 May '08

I am doing what I thought was a simple volume test that OpenSER should be able to handle, but the results I am getting so far show it is not handling the load I'm sending it. Here is my configuration: - OpenSER 1.3.1 - Simple script that uses OpenSER as a proxy to forward requests to a carrier. All it does is rewrite the host and port of the R-URI and relays to the carrier. - children=16 - shared memory set to 1 G. (-m 1000) - using transaction module to handle the requests. - Sending 10 INVITE requests per second to OpenSER using Asterisk. When I do a "tcpdump" trace of the network traffic to/from OpenSER, it is clear that a large percentage of the INVITE requests sent to OpenSER were not handled. Asterisk needed to resend the INVITE requests several times before OpenSER would handle them, and in about 20% of the cases Asterisk terminated the INVITES because it reached the timeout of 30 seconds without any response. If I go directly from asterisk to the carrier, this test works without any issues. I'm not sure what the limitations are of OpenSER, but this seems like something it should be able to handle. Any help or information on how to configure OpenSER so it will work would be appreciated. Thanks, Brian.

[OpenSER-Users] openser trunk performance
by jh＠tutpro.com 30 May '08

30 May '08

also i did some performance tests on openser trunk in order to clear doubt that has been expressed recently. with only 4 child processes and several radius/mysql queries per invite, i was able to achieve 50 new calls per second using sipp including radius accounting to database of each call. this was on my two years old laptop and everything was running on the same host. i didn't try yet how many calls i could have achieved before retransmissions. i'm satisfied with the result and don't think that there are any performance issues with openser trunk. -- juha

[OpenSER-Users] Corrections in rr module documentation version 1.2.X
by Ruchir Brahmbhatt 30 May '08

30 May '08

Hi, I've noticed some mistakes in documentation of rr module in version 1.2.X. 1.5.6. is_direction(dir): Incorrect sentence: As for checking it's used the "ftag" Route header parameter, the append_fromtag (see Section 1.4.2 module parameter must be enables. Also this must be call only after loose_route() (see Section 1.5.1). Correct sentence: As for checking it's used the "ftag" Route header parameter, the append_fromtag (see Section 1.4.2 module parameter must be enabled. Also this must be called only after loose_route() (see Section 1.5.1). Thanks, Ruchir Brahmbhatt Director Ecosmob Technologies Pvt. Ltd.

[OpenSER-Users] Scrolling through resultset
by mark morreny 30 May '08

30 May '08

Hi, If I want to walk through a resultset of numbers, how can I do that? I have tried: $var(index) = 1 while (is_avp_set($var(i:$index) ) $var(index) = $var(index) +1; However $var(i:$index) won't work. I am wondering if someone can tell me how I can correct it. The other question I have is about psuedo-variable. Is there any psuedo-variable can give me the IP of the Openser server? Thanks, Mark

[OpenSER-Users] Explanation of 0x02 in "t_relay()" ?
by Iñaki Baz Castillo 30 May '08

30 May '08

Hi. I read in "t_relay" doc: -------- 0x02 - do not internally send a negative reply in case of failure. It applies only when the transaction is created. By default one is sent. Useful if you want to implement a serial forking in case of failure. -------- Could you please explain it a little more? I use failure_route with append_branch and before it OpenSer doesn't send back a negative reply to caller (in fct it would end the transaction). What the purpose of this bit option? Thanks a lot. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] Need help with proxy_authorize for NATed UA
by mark morreny 30 May '08

30 May '08

Hi, I am using the same UA and Openser to do two tests. For the first case, UA is pointing to the external IP of openser.; the other test points the UA to openser's local ip. Registering is ok for both cases, but when I try to do an INVITE, the UA pointing to the local IP works whereas the one pointing to the external IP fails during proxy_authorize. 88.251.45.4 -> external ip of the entire network 192.168.1.104 -> openser's local ip 192.168.1.100 -> UA's local ip Here is the INVITE with authentication digest from the UA pointing to the external IP address of openser: U 88.251.45.4:59864 -> 192.168.1.104:5060 INVITE sip:1005@88.251.45.4 <sip%3A1005(a)88.251.45.4> SIP/2.0.

Thanks in advance for your help. Thanks, Mark

[OpenSER-Users] Problems with (RE-)REGISTER
by Lucio Maciel 30 May '08

30 May '08

Hi, I am having a situation where the client sends each RE-REGISTER with a new Call-ID, causing it to create a new entry in the location table. The problem is that this client sends the Re-REGISTER in a Expires/2 time, and as the RFC says, the 200ok is sent with the 2 contacts, with each expire, then the client receive this 2 contacts with 2 expires and "thinks" that it should renew the REGISTER for the old contact and sends a new REGISTER, with a new Call-ID, and adds another entry in the location table, which causes the response returns 3 contacts with 3 expires, and so on... There is some way to handle this issue? Thanks Lucio
