RE: [Serusers] mediaproxy + ser0.8.14 problem

by Dave Bath

Hey Arne, No, i'm only using mediaproxy - no nathelper. The NAT: lines are my own debug lines added to various stages of ser.cfg, indicating which bit it's doing. ie. NAT: Request from RFC Private IP Detected --> mediaproxy flagged is when the nat test is performed NAT: Caller is NAT'd (destination offline) --> enable reply processing is when t_on_reply is set for a NAT'd caller and NAT: Invite received --> enabling media proxy is when use_media_proxy() is called. Using the rptgenerator script i can generate media sessions fine, so i know that python/mediaproxy is up and running as it should be (well, nearly anyway) it's just that as soon as ser attempts to call use_media_proxy() it crahses out...!

I have been around and around the houses trying to figure out why as soon as use_media_proxy() is called, ser crashes out. I have checked permissions (I think!) for the mediaproxy sockets from ser... if I use the util script to generate media sessions all is fine, and they can be seen on the web interface, so I know that bit is working... It just seems that as soon as I call it from within ser, all goes wrong... *A very confused Dave* Hi all, Have been trying to get media proxy to work with 0.8.14 and am not having a huge amount of joy. Basically the route processing seems to be fine, but as soon as ser attempts to actually pass traffic through media proxy it crashes out!

I may have a problem with symmetric/asymmetric clients, but I don't think ser should actually crash like that... does anyone have any ideas? Dave

[Serusers] Asterisk Style Routing

by Michael Shuler

Is there anything out there in SER that will allow it to handle more advanced and dynamic routing verses hard coding everything into ser.conf. For example I want to be able to setup a hunt group that rolls over into a voice mail server. But the number of members in the hunt group and the voice mail box/server can change dynamically via a MySQL table. For example in Asterisk style (which I am used to): Exten => 1231231234,1,Dial(SIP/Phone1) Exten => 1231231234,2,Dial(SIP/Phone2) Exten => 1231231234,3,Dial(SIP/Phone3) Exten => 1231231234,4,Dial(SIP/Phone4) Exten => 1231231234,5,Dial(SIP/VMServer/${EXTEN}) How can this be done in SER throuhg dynamic lookups? The reason why I ask is I am about to start work developing a module for it that can do this type of thing but I didn't want to reinvent the wheel. Thanks! ---------------------------------------- Michael Shuler, C.E.O.

Re: [Serusers] call disconnect

by Jiri Kuthan

the answering system should support session timer or other inactivity detection mechanisms and generate BYE eventually. -jiri At 03:04 PM 8/10/2004, Vitaly Nikolaev wrote: >Content-class: urn:content-classes:message >Content-Type: multipart/alternative; > boundary="----_=_NextPart_001_01C47EDA.81641567" > >Hello, > >I tried to search about this question on the web but could not find anything. Probably I used incorrect keywords. The situation is: customer call from SIP device thru SER to some place. SER terminate call to Cisco GW.

[Serusers] rtpproxy v20040105 crashes

by Klaus Darilion

Hi! I'm using ser 0.8.12 and the rtpproxy v20040105. Everything is working fine but sometimes (every 2 weeks) the rtpproxy crashes (ps -A shows no rtpproxy anymore and there is nothing in syslog) during a call. Are there any known issues with this version? Is the HEAD version more stable? Are there ways to track down the problem? regards, klaus

Re: [Serusers] has any body got success with ser-0.8.12 with cpl-c module

by Richard

Did you upload the cpl? cpl_bin needs to have the compiled version of the xml script. You can use CPLED to upload it via SIP. Then use cpl_process_register() in the script to accept it.

RE: [Serusers] mediaproxy + ser0.8.14 problem

by Arne Scheffer

Dave, Are you not using nathelper/rtpproxy mixed with mediaproxy ? This will not work as the 2 are not compatible (see docs). I am using only mediaproxy and never see any log info with ..... NAT: ....... Arne. -----Original Message----- From: serusers-bounces(a)iptel.org [mailto:serusers-bounces@lists.iptel.org]On Behalf Of Dave Bath Sent: dinsdag 10 augustus 2004 17:41 To: serusers(a)lists.iptel.org Subject: [Serusers] mediaproxy + ser0.8.14 problem Hey guys... please, does anyone have an thoughts on this? I have been around and around the houses trying to figure out why as soon as use_media_proxy() is called, ser crashes out. I have checked permissions (I think!) for the mediaproxy sockets from ser... if I use the util script to generate media sessions all is fine, and they can be seen on the web interface, so I know that bit is working... It just seems that as soon as I call it from within ser, all goes wrong... *A very confused Dave* Hi all, Have been trying to get media proxy to work with 0.8.14 and am not having a huge amount of joy. Basically the route processing seems to be fine, but as soon as ser attempts to actually pass traffic through media proxy it crashes out!

I may have a problem with symmetric/asymmetric clients, but I don't think ser should actually crash like that... does anyone have any ideas? Dave

[Serusers] mediaproxy module

by Arne Scheffer

Hello all, I have done some tests with the mediaproxy. Works nicely behind different types of NAT. Also got the mediaproxy monitor page up too. Now I am running into something strange. I have the impression that all calls are now being sent throught the mediaproxy ? Also calls between 2 public IP endpoints, they show up in the mediaproxy webinterface as active. Is this correct ? I am using the sample ser.cfg file and CVS 25-7-2004. thanks, Arne.

[Serusers] 483 - too many hops error -

I found documentation on the 483 - too many hops error and what to do about it, but I guess I don't have a handle one the concept, just like many others I guess. Here is the information I am using. Sign-in name - morriss(a)orau.net username - morriss password - xxxx my workstation is 10.5.10.1 SER server is 10.0.2.1 (comm01.orau.gov) the sip service records for dns are comm01.orau.gov SER version - 8.12 running on Redhat 3.0 ES workstation software - Windows Messenger 4.7.2009 Please take a look at the ser.cfg and ngrep below and see where I have the uri not set properly.
