Hi! I'm connecting to a Cisco PSTN Gateway for international calls. I'm using a Port Restricted Cone NAT. I can make calls and make a hangup with MY phone, but if the callee at the other side of the gateway hangs up, I do not get the BYE-Message. That could be the problem of the Restricted Cone NAT... or someone has another idea? Thanks! Sebastian

[Serusers] exec_msg problem

by Sam Lee

Hi, Have anyone seen this kind of error message before : ERROR: exec_msg: cmd echo $SIP_HF_CSEQ : $SIP_HF_FROM to $SIP_HF_TO >> /var/log/syslog failed. exit_status=-1, errno=32: Broken pipe This command is actually in my ser.cfg where i capture this few environmental variables and push them into my /var/log/syslog. It effectively went in, but i still see this error message. Here is the original code in ser.cfg : exec_msg("echo $SIP_HF_CSEQ : $SIP_HF_FROM to $SIP_HF_TO >> /var/log/syslog"); Please help! Regards, Sam

RE: [Serusers] Problem : Can SER process the reINVITE messages pr operly?

by Ricardo Martinez

Thanks again Alberto. Are you using the ser.cfg from onsip.org? I'm using it, and i can't make it work with reinvite to a nat'd endpoints. Can you give me some hints here?. For example what version of mediaproxy are you using?. If you're using the onsip.org configuration, Did you modified this configuration to make it work for reINVITE's? Hope you can help me, Thanks again Regards, Ricardo Martinez.- -----Mensaje original----- De: Alberto Cruz [mailto:acruz@tekbrain.com] Enviado el: Miércoles, 27 de Julio de 2005 16:50 Para: Ricardo Martinez CC: 'serusers(a)lists.iptel.org' Asunto: Re: [Serusers] Problem : Can SER process the reINVITE messages pr operly?

It would help if you check either /var/log/messages or /var/log/syslog for error message pertaining to SER.

[Serusers] SER + SERNAT + MySQL

by Truong Chi Thanh

Hi all, My name is chithanh. I'm working at Vietnam. Now I'm using with SER. I have a case with SER. | ser database | | | ============================ || || | SER (5060) | | SERNAT + nathelper + rtpproxy (5082) | || || | user1 | | user2 | Explain : user1 registered SER ===> SER save("location") for user1 into table "location" of "ser" database. user2 registered SERNAT ===> SER save("location") for user2 into table "location" of "ser" database. My purpose : user1 can call for user2. user can call for user1. Real when I run with this case. User1 can't call for User2. (although i had setted db_mode=1 for both) because : + User1 INVITE User2 ==> SER lookup("location") into SER's memory. Not lookup in ser database. + Use2 INVITE User1 ==> SERNAT lookup("location") into SERNAT's memory. Not lookup in ser database. I want SER and SENAT when lookup("location"), they must lookup in table "location" of ser database. How do u to solve for this problem ?

[Serusers] SIP Service Providers supporting Windows Messenger 4.6

by Michael Kendall

Hi, Reading the SERusers digest for a few months has allowed me to read about a lot of very complex and specialized problems. It's a bit intimidating. Although I might some day want to learn to administer a Linux system and run my own SER server, at this point I would rather just become a paying customer on someone else's SER server. Many of the list participants are clearly professionals operating large SIP service providers. But none of these professionals have identified their organizations clearly enough to let me become their customer. Perhaps because the traditions of the list prohibit users from advertising their commercial services. Can someone please give me a recommendation of a SIP service provider which has good service and reasonable pricing. I need a service which will allow me to call between two computers, each running Windows Messenger 4.6/4.7 . I am aware that the latest version, Windows Messenger 5.1 does not allow connecting to third party service providers, and that is the reason that I am using the older versions. The Microsoft site does not tell me how to configure version 5.1 for STUN or for symmetric NAT. Every link that I have found for downloading version 4.6 points me back to the download page at microsoft.com, and microsoft has actually removed the file so all I get from them is a polite apology. Fair enough. So here is an interesting legal question that I suspect a lot of you SER wizards will know the answer to: Is it illegal for third parties sites to publicly offer the download of version 4.6 after microsoft has chosen to stop offering it? It was after all being given away free by Microsoft a short time ago. I am aware that freeworlddialup.com (FWD) is a good no-cost SIP service provider. Does FWD use SER as their server software? The latest version of FWD offers several options for User Agent software, but none of these UAs include a whiteboard feature, which I need for my tutoring service. Therefore, I need a SIP Service Provider which supports Windows Messenger 4.6/4.7 and has some configuration instructions for this particular UA. Hopefully the config instructions will tell me how to set Messenger up for STUN when I have a standard NAT, and for mediaproxy when I encounter a symmetric NAT. Googling for "SIP Service Provider" and "Windows Messenger 4.6" has led me to a lot of dead ends and out-of-date pages, such as the "old FWD site" at pulver.com which has detailed instructions for configuring Messenger 4.6, but the instructions no longer work. "Service provider temporarily unavailable". (permanently) Can anybody offer a Service Provider recommendation or volunteer to take me on as a customer? thanks Michael Kendall

[Serusers] Dest IP

by Sebastian Kühner

Hello, I need the destination IP of the user of the first INVITE message (user -> ser)... but dst_ip == xxx.xxx.xxx.xxx gives me the IP of ser. The problem is that I only want to force the rtp_proxy if the users are behind a Port restricted cone NAT (the scr-ips of them are known) Here is my code: # Force rtpproxy for users that are behind a Port Restricted Cone NAT if ((src_ip == xxx.xxx.xxx.xxx | dst_ip == xxx.xxx.xxx.xxx) && !(uri=~"sip:[0-9]{9,30}@.*")) { fix_nated_contact(); # Rewrite contact with source IP of signalling force_rport(); # Add rport parameter to topmost Via setflag(6); } Has anyone an idea how I can get the IP of the user? For example in the location database? Thanks! Sebastian

[Users] typos in documentation and use_domain question

by Klaus Darilion

Hi! In the uri_db documentation (all parameters): modparam("db_url", ".... ^^^^^^ shouldn't this be uri_db? In the group_radius documentation: modparam("group", ... ^^^^^^ shouldn't this be group_radius? I also wonder about the use_domain paramter in the radius modules. group_radius has this parameter, whereas all other radius modules (uri_radius, avp_radius, auth_radius) do not have this parameter? Is there a reason for this? regards, klaus
