[Serusers] ser, pstn gateways
by Jev 27 Jun '03

27 Jun '03

Hello all, Im using ser, with esteras softphone, and a couple of cisco ata186's. I have to say I really like ser, as it is small fast, and reliable without being over complicated. I would like to know what other ser users and developers use for pstn gateways? I have a openline4 card from voictronix, but there is no software support for sip (When I bought it I thought I would use h.323). I have looked at cisco's pstn gateway modules, but was turned off them because of price, and lack of clear straight forward information to name but two reasons. Ideally what I would like to have is a solution that would support at least 4 pstn lines (expandable to maybe 8), that would run on FreeBSD (or at worst linux), works well with sip & ser, with high quality audio, and minimal delays when dialing in out. TIA, -Emil

[Serusers] User Based Dialplans
by Fernando Nachtigall 07 May '03

07 May '03

Hi All, I need to implement an used based dialplans module on SER, so that depending on the user information stored in the database, a certain prefix should be inserted in the called number. Has anyone had a similar issue? Thanks Fernando --- Outgoing mail is certified Virus Free.

[Serusers] Rewriting URI in the Contact field
by Maxim Sobolev 24 Feb '03

24 Feb '03

Folks, I need an advise on how to better implement one feature, which isn't currently present in SER. We need to allow UAs behind NAT properly register with the registrar - by "properly" I mean that host:port portion of URI in Contact field should not be used, but host:port the request came from should be used instead. By definition we know that those UAs will support symmetric SIP signalling, so that this scheme will work just fine. In my opinion there are two ways to do it: either add new rewritecontact* family of functions similar to rewritehost ones. or add a new flag for the save() function. This is where I need your help - which implementation looks better for you (or maybe you have even some better idea), since we are really interested in inclusion of our changes into the mainline to reduce our local hacks. Regards, Maxim

[Serusers] Some patches for integration
by Maxim Sobolev 24 Feb '03

24 Feb '03

Folks, Attached please find several patches for ser 0.8.10. They do the following: 1. Removes hardcoded `/usr/local' from Makefiles and replaces it with LOCALBASE variable setable in the top Makefile.defs. This should make life of packagers easier. 2. Allows to override PREFIX variable with something else from environment. 3. Adds support for FreeBSD doc/man directories layout. 4. Adds some missed -I's into radius modules. 5. Fixes radius modules to use the same symbolic avp names as in dictionary. 6. Adds support for recording source port in msg structure and adds it in "Noisy feedback". This should be extremely useful for debugging various SIP&NAT scenarios and later could be re-used to implement `rport' support described in my previous message. It would be nice to have those patches integrated into the next release. Thanks! -Maxim

[Serusers] NAT Traversal Technique Survey
by Jiri Kuthan 23 Feb '03

23 Feb '03

Folks, please help me -- share with me techniques for NAT traversal you use and have hands-on experience with. People repeatedly ask about it, and I'd like to create an FAQ that reflects deployment experience and as wide user feed-back as possible. Just tell me the technique you use, its requirements, limitations, the devices it is known (not) to work with, why you prefer one method over the other, etc. I'll then try to compile it in an FAQ. So please send me an e-mail, an example is attached. I will appreciate any practical details. Thank you, -Jiri ---------------------------------------------------------------- technique: using symmetric communication requirements: phone devices that support symmetric communication; existing species: Cisco's ATA configuration practice: ATAs need to be configured to advertise public address in signaling, or learn it from REGISTER replies; alternatively, one can rewrite signaling using ser's nethelper module; one needs to rewrite SIP anyway because ATAs don't advertise their symmetricity; see www.foo.bar for info on configuring ATA... limitations: non-symmetric devices, like Messenger don't work; misc: ATA has no display, that's why I am anxiously waiting for more vendors to support symmetric signaling ---------------------------------------------------------------- technique: UPnP requirements: NATs and phones with UPnP support; Messenger and snom are known to support UPnP; there is linux support for it configuration practice: of course, upnp requires by definition no configuration ;-) (I'm not serious -- anyone actually tried it?) ---------------------------------------------------------------- technique: geek tweaks: set-up port forwading manually configuration practice: you need to configure NATs to split its public-side port numbers accross your private-side phones, and configure the phones (if they allows so) to use these port numbers; also, phones need to be configured to use publicly reachable address in their payloads requriements: configurable NATs (many residental NATs are configurable) and configurable phones (ATAs do that, I heard pingtel did it too) ---------------------------------------------------------------- technique: ALG requirements: SIP-capable NAT (like Intertex or Cisco/PIX) issues: intertex freezes my ssh connections after some time on-line and elderly models don't like all Ethernet devices; when things don't work, the red-button off-on helps sometimes ---------------------------------------------------------------- technique: STUN requirements: STUN-enabled phone (like k-phone, snom) limitations: doesn't work over symmetric NATs (words-of-mouth propaganda has been telling me that many residential NATs are fortunately not symmetric, but I don't know how objective this information really is) ---------------------------------------------------------------- -- Jiri Kuthan http://iptel.org/~jiri/

[Serusers] Routing to the PSTN
by Phillip Haynes 01 Feb '03

01 Feb '03

Hi, I have set up the SER and its working. The only problem is I cant get the routing logic to simultaneously route to either the User Loc or the PSTN. Its only doing one of the other. I am new to SIP, can u show me a sample script that will do both at the same time? Best regards, Phillip

[Serusers] Windows Messenger authentication fails.

Hi Daniel, The problem related with the permition to use de jabber gateway seems to be solved. Now I have a new problem. In the same scenario (Messenger sending a message to Jabber client) the messenger receives from the jabber gw the following error message: " ERROR:Connection to Jabber server lost. You have to login to Jabber server again (join the conferences again that you were participating, too)<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />" Can you figure what is happening here?

Hi Nils, thank you for your suggestion. 192.168.11.237 is my sever IP address and realm.
