[Serusers] re: i have a problem and i'm so desperate i'm offering money to anyone who can solve it

by Yair Hakak

Hello all, I have a continuing problem with registering a grandstream BT102 to SER. It is behind a router but i am pretty sure NAT is not a problem because i got the phone to register to asterisk perfectly. The problem is this: 1. i cannot modify the SRV records on my server - it is set up with a DNS A record for "phone.myserver.com" 2. i can register x-lite to the server fine, by putting the IP address in the SIP proxy and outbound proxy fields, and using "phone.myserver.com" as the Domain/Realm. SER checks users against phone.myserver.com (digest authentication) and the grandstream doesn't register (which makes sense, because on the grandstream you can't set the domain/realm and the proxy server separately) however: according to the grandstream website: What if my SIP URI domain is different from the SIP proxy server FQDN (Fully Qualified Domain Name)? With firmware 1.0.3.60 and later, you can put the your SIP URI domain name into the SIP Server field, and put the actual sip server FQDN into Outbound Proxy field. The phone will use the domain name in SIP Server as part of SIP URI but send and receive SIP messages through the SIP proxy server defined in the Outbound Proxy field. -but that doesn't work, i still get 401 errors i am so desperate that i will give the first person who gives me information to solve this problem $20 of amazon credit (you can use it to get one of those spiffy new linksys PAP2 devices) as a token of appreciation. thanks, yair p.s. don't tell me to enable SRV. I know this would probably solve the problem, but it's not an option. if x-lite can register without SRV records i'm pretty sure the grandstream can as well, i just don't know how.

[Serusers] SER and SRV records

by Henrik Pfluger

We would like to do failover for our backend gateways. I though SRV records with different priorities would be an elegant solution to this. Does SER fully support SRV? Will it forward to the next prioritized address in the SRV if the high priority address does not answer? Does it do load-balancing using the weight entries in SRV records? Regards, Henrik

Re: [Serusers] Variables

by Jiri Kuthan

SER does not support variables (yet). Unstable version supports global flags which can be driven externally too (gflags module). -jiri At 10:01 PM 9/25/2004, Michael Shuler wrote: >Is it possible to define global or local variables in SER to make routing >decisions?

[Serusers] Variables

by Michael Shuler

Is it possible to define global or local variables in SER to make routing decisions? For example I would like to do the following: MyVar = 1; If(MyVar < 10) { MyVar++; } Else { MyVar = 1; }; ---------------------------------------- Michael Shuler, C.E.O. BitWise Communications, Inc.

[Serusers] serving a domain with two ser proxies on a private network and the internet -- RFC

by Morten Kuehl

Hi, I do have two ser servers (0.8.14) and a pstn gateway (*) and a rather complex setup to build. One ser server and the pstn gateway are inside a private network that is shielded from the internet by a cisco pix firewall. This ser server should act as a sip registrar and outbound proxy for all clients that are inside the private network and should furthermore handle incoming calls from the pstn gateway. The other ser is on the public internet (public ip) and the firewall that secures the private network allows connection from the internal private ser server to the external one and vice versa (translating the private ip from the internal ser to a public one). Clients from the internal network cannot and must not traverse the firewall. I want to configure the internal ser in a way that it acts as a sip and a rtp registrar and outbound proxy (rtp with mediaproxy for video if possible). All calls from internal clients and the pstn gateway should be accepted by the internal ser and either be handled on that server directly (destination also on the internal network) or be forwarded to the external server to be handled there. As stated above, all sip messages and rtp streams can only leave the internal network via the internal ser server. Calls from external clients to internal clients should be accepted from the external ser server and be forwarded to the internal one with the rtp streams and sip messages being proxied by the external ser server. Incoming sip and rtp traffic for internal clients is only allowed from the external ser to the internal ser by the firewall. Both sers should serve the same domain as a registrar to allow clients to be mobile and either connect to the internal ser if on site or to the external ser if at home or somewhere else. There are two dns servers, one internal on the private network and one external, the internal one (used by all internal clients) replies with the private ip of the internal ser and the external (public dns server) replies with the public ip of the external ser when asked for sip.xyz.com. The external ser has already a running version of mediaproxy on it and both ser servers authenticate their users by a common database on another server. Finally it would be great if presence would work across the two servers as well as having accounting on a central database. Running a common database for both sers on another server would be possible if required. Has anybody a similar setup or can provide me with some ideas et c.? Thanks and have fun Morten

[Serusers] HELP - lookup("aliases") not working

by Java Rockx

Hello all. I'm using ser from the CVS head branch. When my ser.cfg calls lookup("aliases") nothing seems to be returned. I have a real user named "1000" which works since I can originate and recieve calls. I need to alias this because I need this user to receive calls from the PSTN. I have used serctl to create an alias with the following command: serctl add 2025551234 sip:1000@mycompany.com I also verified that this new alias is in the mysql database ser.aliases table Now I make a call from a land line to 2025551234 and I use ngrep on my sip proxy to monitor port 5060. I see that a 404 is always returned after the statement if (!lookup("location")) { # off to highway 404 } I have the lookup("aliases") command prior to the lookup("location") command. I have also experimented with creating an alias such as "1001" for user "1000" and dialing it from another registered UA on my softswitch only to get the same result --- a 404. How can get the lookup("aliases") to return something? Regards, Paul _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com

[Serusers] Question about usrloc

by Runar Lyngmo

Hello Ser users and developers! I have a question about userloc. I'm authenticating my sip users (Allied Telesyn RG613-TX boxes) against mysql with a given username (msn1-macaddress / msn2-macaddress) and auto generated password. Authentication works fine, but my question is related to how ser stores users location in the location db. Example: Username: msn1-12345678 Phonenumber: 12345 Contact: sip:12345@192.168.1.1:5060 When this user is register the following I added to the location db: Username: 12345 Domain: Contact: sip:12345@192.168.1.1:5060 +++ My question is regarding the username column, is it possible that it contains the username of the sip user, not the username in the contact uri? Regards Runar Lyngmo
