[Serusers] Voicemail Feature
by Ahmed Abdoulla 31 Mar '03

31 Mar '03

Dear Madam/Sir, We are a data communication provider in Egypt, and we are very much interested in deploying SER. We are particularly interested in having a voicemail feature as one of our offerings, and we have tried the CVS (8.11) version but we have noticed (naturally) that it's not stable yet. Could you please give us a rough estimate on when you believe a beta or alpha release will be available? Thanks a lot for your time and cooperation. Regards, Ahmed Abdoulla Quality Unit Manager Acting WebDev Unit Manager TE Data 11, Cleopatra St, Heliopolis TEL : +20-2-4166660 FAX : +20-2-4166700

[Serusers] Checking for unregistered user
by Luke Gasteiger 30 Mar '03

30 Mar '03

Hello Is there a built in function that can check to see if a user exists (not registered). I have a need to send different error codes depending on whether a phone number is unallocated or it is allocated but not registered. What I require is this if (!lookup("location")) { if (user does not exist) { sl_send_reply ("604", "Does not exist anywhere"); break; } else { sl_send_reply ("404", "Not Found"); break; }; }; if (!t_relay()) { sl_reply_error(); }; Thanks Luke

[Serusers] affordable PSTN gateway
by Jiri Kuthan 30 Mar '03

30 Mar '03

during my pstn gateway survey, some people asked about cheap PSTN gateways. Let me share what I know, speak up if you know more. analog ------- AudioCodes and AlliedTelesyn provide SIP FXO gateways wuith four ports for about $1000. We have both of them in our lab (i.e., they do exist) but haven't tested them yet (i.e., we don't know if they work). MediaTrix might have some too, perhaps sightly cheaper, but they denied shipping to us as we are not in their interoperability club (which makes me cautios about their interoperability). arrayvox was claiming to have some very cheap ones, but I neither know if they shop nor if they work. The same for welltech. in general, not only is a challenge to make the sip part of it work, but also the analog -- tone recoginition may be pretty challenging. It differs country from country and pbx from pbx. digital ------- I don't know -- some people meant Asterisk would do that, some other meant not really. other ----- someone told me vegstream (both digital and analog) was good and afforable. more can be found at http://www.iptel.org/info/products/index.php?category=gateway&name=Gateways… -- Jiri Kuthan http://iptel.org/~jiri/

[Serusers] Regarding OPTIONS
by Geetha Shree 30 Mar '03

30 Mar '03

hello every one, I am facing some problem in the OPTIONS method. I am getting "404 not found" response. I wanted to query the server for its capabilities. I wanted to know which are the methods it supports from the 200OK response of my OPTIONS method. My packet was as below OPTIONS sip:192.168.1.9 SIP/2.0 Via: sip/2.0/UDP 192.168.1.9:5060 Max-Forwards: 70 To: <sip:192.168.1.9> From: <sip:geetha@192.168.1.21>;tag=1047012665620 Call-Id: 82963748691a049dc5aadf81b162c894(a)192.168.1.9 CSeq: 1 OPTIONS Contact: <sip:192.168.1.9:5060> Accept: application/sdp Content-Length: 0 Can some one tell me How SER works for OPTIONS method and why am i getting that "404 not found" response.Is there some problem with my packet?

A possibility is our FIFO UA, part of SER. It was built to couple SIP-unaware applications with SER over stdin/stdout interface. We use it for our click-to-dial and voicemail application. The adventage is it is pretty simply and you don't need to run into stack details. For sake of completeness: some in our team would prefer a stand-alone SIP stack better, but we don't have any yet. If that is interesting for you, we will be glad to provide you with guidance. -Jiri

[Serusers] More on PSTN gateways....
by Dan Austin 29 Mar '03

29 Mar '03

I'd guess that many folks on the list are as interested in finding a low cost PC based gateway as I am. My research has uncovered on possible candidate, and caused some confusion at the same time. I came upon a product called Wildcard T100P. A single loop T1/PRI card with linux drivers, for the oh-so-reasonable price of US $500. The catch seems to be that there is no gateway code written to date to use the card, at least no code whose only function is to be a gateway. There is also a single port FXO card for US $100 It turns out that the OSS PBX Asterisk can leverage the card, has support for SIP, and is in general really cool, but too feature rich to be used as a PSTN gateway. Sure the price is right (free). Has anyone worked on or with the Wildcard? Details about the card can be found at http://www.zapatatelephony.org/ What is lacking appears to be a package that can leverage the Wildcard library with a SIP frontend. I am tempted to try to workout what the framework of such a package would look like, and try to rough out some code. The problem with that is I'm no coder*. The source for the Wildcard driver is well documented, so I may try anyways. Can anyone recommend a SIP stack for Linux, where the code is documented well enough so that someone not an expert on SIP programming can figure it out? * Not professionally. I have needed to debug C source before, and have written small tools that to be honest were not at all elegant. Dan

[Serusers] ENUM tel records
by Michael Haberler 28 Mar '03

28 Mar '03

Juha's ENUM lookup routine currently looks up the e164.arpa tree for a phone number and searches for a sip record, which is returned and used to rewrite the current uri. ENUM also allows tel: records amongst others. What, if anything should be done with those, and how should they be treated relative to sip records? I would assume a tel: record could be interpreted as a kind of call forward, which could be arbitrarily staged. One way of handling this could be to explicitely look for tel records with, e.g., an argument to enum_query() to have any tel records rewrite the current uri, and then go on to look up the result (maybe recursively which requires a loop counter and an abort condition). so the resolution could look like while (loopcount--) { enum_query("tel"); enum_query("sip"); } what do you think? -Michael

hi, thanks. what i am looking for is not a full fledged accounting module. i need to know if currently generated call records can be put into MySql database. if yes, is there any tool available to view these records? rgds, sunithi -----Original Message----- From: jh(a)lohi.eng.song.fi [mailto:jh@lohi.eng.song.fi] Sent: Thursday, March 27, 2003 8:21 PM To: Sunithi JP Cc: 'serusers(a)lists.iptel.org' Subject: RE: [Serusers] help with accounting using mysql Sunithi JP writes: > thanks for the quick response. cud u pls tell me if accounting thru RADIUS > is working? it depends how you define "working". the problem currently is that there is no easy way to know if a bye, for example, was sent by a local or foreign user. before that is information is available, any accounting is difficult to make to "work". if you mean a version of radius accounting that doesn't crash and produces "records", i'm sure that such a module will be included in the next release. -- juha
