[Serusers] SIP UA that supports PGP
by Wouter Prins 03 Oct '03

03 Oct '03

Hello, Does someone know of a SIP UA that has support for end-to-end encryption by using PGP or some other application for encryption of SIP message body's? Does SER have support for hop-to-hop encryption or some other sort? Would love to hear it! Thanks in advance! Met vriendelijke groet, Q&I Wouter Prins Q&I NEDERLAND BV Delftech Park 35 - 37 P.O.

[Serusers] voicemail on failure_route and user is subscriber questions

I've tried several times and although Jiri says the logic has to be different because you can't create a transaction two times, I can't figure out how to make it work, and I haven't found any documentation detailing this issue. I have seen the errors in the logs that verify what Jiri is saying. Jiri said that he'd introduce new commands to hide tansaction functionality from script writers, but I'd like to know how to make this work without those new commands. Also, is there a command that queries whether or not a sip message is for a user in the subscriber table? I need to know if the user exists regardless of whether or not lookup("location") = true.

[Serusers] 400 fifo_uac: next hop address expected
by jaime.gil＠orange.co.uk 03 Oct '03

03 Oct '03

Hi, When trying to send a SIP message through the fifo server, it comes back with an error: "400 fifo_uac: next hop address expected" What could be causing this and how could we monitor what gets in and out of the fifo?

RE: [Serusers] Implementing Voicemail

>> I did place this portion inside the myself check >>and it still tries to transfer to vm after the time expires. >I'm puzzled -- did not you want to transfer to vm after the time expires? I will try to make this clearer. I am behind an ATA with a SIP proxy of 209.242.10.153. If I call someone else registered on my domain and they are not available, I want to go to voice mail. If I call 1-800-555-1212 from my phone, I do not want my sip proxy to reroute the call to voicemail after 10 seconds if no one answers(or ever for that matter). Right now if I dial 18005551212 from my handset, I see the destination as sip:18005551212@209.242.10.153 on the server which matches to myself and ser tries to send it to voicemail. Someone calling into the network is not a problem. They will never hit our server unless the destination is local. >>This is the part that I really need help with! When the call timer >>fails, the call goes to the route[1]. How do I get it into voice mail >>from that point? >See bellow, I think that should work. This is what I had originally, and I get the following syslog.

The above line will make you loose the user part of the URI, and is therefore not a working solution ... we'd need a function to reset the branch status value here, which afaik does currently not exist ... axelm

[Serusers] Directory Services
by Ng, Soo Sim 03 Oct '03

03 Oct '03

I am looking for the following feature A list of Directory Services is displayed on the serweb, (for example, Hotel List, Emergency List, Airlines List ect). A registered user will subscribe to the intended list (Eg a hotel will subsribe to the hotel list). A normal user will be able to view the selected list. The seleted list show only online members at that time. Off-line members will only be shown when they are login in. Can this feature be done? Thanks

RE: [Serusers] caller-id with raius using sip-rpid
by Steve Dolloff 03 Oct '03

03 Oct '03

At the top of the config I have the following statement.... if (method=="INVITE") { record_route(); if (!radius_www_authorize("")) { log(1,"radius auth failure"); www_challenge("voip2.test.net","0"); break; }; append_rpid_hf(); }; If I call a phone with caller-id and my username is 256, it shows 256 on the phone, if I call with a username of test, it shows 4534 on the handset even though I have the sip-rpid set to 222. Stephen Subject: Re: [Serusers] caller-id with raius using sip-rpid Retrieving caller-id when users register doesn't work because REGISTER messages are processed by the server and the server generates a reply only. What you need is to insert Remote-Party-ID header field into INVITE message, to make it work you must authenticate also INVITE messages. My guess is that you do not authenticate INVITE messages and therefore there is nothing append_rpid_hf can add. Jan.

[Serusers] nathelper
by Dovid 03 Oct '03

03 Oct '03

Can I replace nathelper.c from ser-0.8.11 (release) with the latest from dev and recompile? I tried that and recompiled just nathelper.so. What happens now is that for fix_nated_sdp or force_rtp_proxy I get 'ERROR: extract_mediaip: no `c=' in SDP'. What is happening is that in each of those functions it calls extract_mediaip twice. The first time is OK. The 2nd it gives this error. Then when it sends out the request, it has the correct IP AND the proxy IP (e.g. 1.2.3.44.3.2.1) Does it need the full latest CVS to work? I get a mysql error with that. Thanks in advance. Dovid
