Gentlemen, If I was using SER as a proxy server to deal with clients behind NATs, I can understand the concept - the sip proxy rewrites the header information to correct for the NATed client. Where I have a large "hole" in my understanding is concerning inbound calls from PSTN. Currently, these arrive at our Asterisk box which has no knowledge of the clever things SER should be doing to deal with the NATed clients. Can anyone please fill in the gaps in my understanding ? Better still.....can anyone let me have a look at their Asterisk and SER config files on a system that works ??? Jim -- --- www.yakara.com

Re: [Serusers] Fwd: No RTP

by Voipers Portugal

SER does not handle RTP messages, only SIP messages.

[Users] Asterisk & Openser

by Ronald Wiplinger

I want to use Openser to register all phones. If the phone is allowed (paid) than it should be able to reach a certain gateway (flat rate to certain numbers) Distinguished via mysql database. If the destination number is not in the flat rate, than the call should be forwarded to Astersik to handle the call (prepaid card) If features are requested, than should be also Asterisk handle it. Is there a starting point for this set-up?

[Users] connection between openser and mysql both in different machine

by unplug

How does openser connect to mysql which is not in the same machine (say openser is in 10.0.0.1 and mysql is in 10.0.0.2)? I have configured all mysql statement in the configuration file as "mysql://openser:openserrw@10.0.0.2/openser" but openser failed to start. Below is the error message from the log. Jan 21 14:25:51 owthkems01 /usr/local/sbin/openser[12298]: new_connection: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) Jan 21 14:25:51 owthkems01 /usr/local/sbin/openser[12298]: ERROR:domain_db_init: cannot initialize database connection Jan 21 14:25:51 owthkems01 /usr/local/sbin/openser[12298]: ERROR: domain:child_init(): Unable to connect to the database Jan 21 14:25:51 owthkems01 /usr/local/sbin/openser[12298]: ERROR:init_mod_child: Error while initializing module domain, rank 1

[Users] question about avp

by unplug

Say I have a record in the table usr_preferences with username, attribute=function, value=voicemail. I use avp_db_load("$from/username", "s:function") to get the value. I can print out the value in xlog function by using $avp(s:function). How can I put that value in the header by using append_hf? As I found that it doens't work if I use append_hf("P-hint: $avp(s:function)\r\n"). In other words, how can I get back the value of the variable stored in avp for other functions processing?

RE: [Serusers] SER frontend

by Barta János

Hello! I'm again :-). If I use the next config in my ser.cfg, then the authentication works fine, but the presence does not. if (!www_authorize("domain.hu", "subscriber")) { forward( csps.domain.hu, 5060); break; }; But if I insert the save("location") line in my config file, then the presence info will be good, but the authentication will be wrong. if (!www_authorize("domain.hu", "subscriber")) { forward( csps.domain.hu, 5060); save("location"); break; }; Can I mix these two features? Thanks, Jani -----Original Message----- From: serusers-bounces(a)lists.iptel.org [mailto:serusers-bounces@lists.iptel.org] On Behalf Of Barta János Sent: Friday, January 20, 2006 4:45 PM To: serusers(a)lists.iptel.org Subject: [Serusers] SER frontend Hello! I would like to make a frontend SIP perver. For this server will be only one task, to provide the presence information. The architecture: SIP client -> SER ->CSPS. I have a problem with the registration method. I'm using http digest auth. If I forward the authentication messages (to the CSPS), then the SIP client logs in automatically, and in this case I don't have the possibility to type the username/pwd. What is wrong? And I have a second question: Can I use W$ Messenger 5.1 presence under SER? (The 5.0 works fine, but the 5.1 does not.)

Have you checked Python yet. Which version of Python do you use? Run 'python' from command line and type 'import optparse' to see what happens. If there is an error, you do not have the Python module 'optparse'. Upgrade to a newer version of Python or install the module by hand. Regards, Reinhold

[Users] substring function

by unplug

Does openser provide any substring function to get a substring within a string? For example, I have a string "1234abc5678" in avp s:gw, and I want to get "abc" from s:gw.

[Users] uac_replace_from function

by unplug

I am using uac_replace_from function as below. # replace only display and do not touch uri uac_replace_from("35418474",""); After running uac_replace_from function, I get the following message. U 203.193.4.242:5060 -> 203.193.4.226:5060 SIP/2.0 183 Session Progress. Via: SIP/2.0/UDP 203.193.4.226;branch=z9hG4bKaed7.46cc4101.0,SIP/2.0/UDP 10.0.0.52:5060;rport=5060;received=210.184.4.31;branch=z9hG4bKHNHpldVsKca6IYUS.

Call-ID: yTCQvS56ZCZXCHgt(a)10.0.0.52. Server: Cisco-SIPGateway/IOS-12.x. In the normal message, sip message, there is a space between display name and uri. ie. From: "35418474" <sip:882754853589@ow01.owtel.com> However, after I apply uac_replace_from function, there is a space there. How can I add a space such that it looks like a normal sip message? Does the space will affect the caller display?
