[Serusers] SER 0.9.4/ postgresql Registration problems

by H Quintana

Hi, I just updated SER from 0.9.3 to 0.9.4. In both cases I'm using Postgresql. With SER 0.9.3 the REGISTER process works fine, the REGISTER is accepted and then the record is inserted in DB. With SER 0.9.4, I've found that when the "location" is inserted or updated in the DB, SER is generating core. However when SER starts the locations list is read from DB without any problem. Any ideas? Thanks for your help, Humberto __________________________________ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs

[Users] REGISTER expires and replication

by Helge Waastad

Hi, I have a scenario in which I have a little bit of confusion.. I have a redundant setup, two OpenSER, a MySQL cluster and replication of REGISTERs. The UAC sends expires=3600 Both OpenSER's has a max_expires=1800, min_expires=300,default_expires=300 My Sipura-1001 has default expires=3600. In the OK message sent from the OpenSER handeling the REGISTER, expires=1800 is sent back to the UAC which is OK (However the Sipura does not obey this, which also is struggeling, but that is another story....) The replicated REGISTER, hovever, uses the original expiery from the UAC...expires=3600 Do I have to rewrite the expires in the replicated message? -- mvh/best regards Helge Waastad System Engineer Smartnet

[Serusers] SER, and the two firewall problem

by Richard Southwick

Hi all -- We're using SER as a registrar and proxy, and need to deal with the following NAT problem: * SER is proxying to asterisk, which is behind a firewall. * Our users are registering with SER, but their UAs are behind another firewall. We're looking at nathelper and rtpproxy. Two questions: * Will this combo (SER, nathelper, rtpproxy) work in this scenario to solve the NAT and pinhole issues? * Does SER have to live outside the firewall, or is there a way it can be behind the same firewall as Asterisk? Thanks for any insight, Richard

[Serusers] [Fwd: [Sip-implementors] TLS certificate question]

by Adrian Georgescu

Juha, I host for example multiple domains for multiple users. This means that users rely on my services entirely to provide them with identity services. Ideally I would like to present the Certificate of domain X from user in domain X when I forward his calls through my proxy. Alternatively I could say I put certificate with CN=ag-projects.com in all request going outside my domains but then my white-label customers will become yellow. So something to match business with the technicalities is required, don't you think? Adrian > But then, the whole authorization thing would be nonsens. > > Just imagine a host named "sip.badguy.com". This host has a valid > certificate for its hostname. Then, this SIP proxy sends a SIP request > with the header: > From: "Klaus Darilion" <sip:klaus at darilion.com> > > Now, what is the receiving proxy interested in? Does it want to validate > the host or the sender (From header)? there are other ietf means to validate the sender. usually they involve signing of from uri with the certificate of its domain. see for example draft-rosenberg-sip-identity-privacy-00 for a good summary of the issues and problems involved. in proxy-to-proxy case, all that needs to be done is to validate the remote proxy. > IMO, I want to authenticate the sender in the From header. Thus, the > certificate would have to match the SIP domain, and not the host > name. see above. -- juha

[Serusers] Conferencing...

by Voipers Portugal

As far as I have seen, SER itself cannot offer conferencing services, right? Therefore I have also noticed that you recommend Asterisk, SEMS or others. My doubt is, how does SER contacts with those servers? Does SER supports MGCP? I tought not, but if this is true, how do they communicate? If anyone knows where i can see more info on SER conferencing, please let me know. Regards, Jose Simoes

[Serusers] time stamping each SIP message in a dialogue

by Iqbal

Hi I just realised that the date: parameters is not set in each SIP message, am sure this is correct, but wouldnt this be a good idea, I am trying to work out which part of my call is being delayed, and the date command would make it easier. Just compare times between each message in ngrep. Something like what mailservers do, so that you can see if the mail was on a queue for a long time. Iqbal

[Serusers] lcr module based on timeout

by Iqbal

Hi Can the lcr module be deployed in such as way where, if call takes x secs to complete it will go elsewhere..or perhaps even before the invite is sent, a RTT to the gateway is done, and it picks the nearest/best gateway for that prefix Iqbal

[Users] caller id authentication

by jayesh nambiar

hi all, I am trying to implement this feature in my openser 0.10. It is as follows: I allow users in pstn network to dial my gateway number, wherein they get a dial tone and the gateway then forwards all the calls to openser and are processed accordingly. But now I want to authenticate these caller ids. I want to give this privilege only to my subscribers. I had thought of adding the ids in the trusted table as my gateway is in trusted table, but this does not seem to be a good solution. Can I add an extra column in the subscriber table wherin I mention the caller-id for individual users (I give only one caller_id to one user), so that if the user is authenticated then the caller- id for that user should be authenticated. Can it be possible. I was thinkin of using AVPs for this, but I dont get the idea of retreiving the caller-ids from the table to check if the caller-id is valid. Can someone help me in this regard. thanks jayesh --------------------------------- Yahoo! Music Unlimited - Access over 1 million songs. Try it free.
