[Serusers] SER to be used to forward Calls to/from an ITSP from Asterisk
by Chris 27 Jul '04

27 Jul '04

Hello, I'm very new to SER, been using * for a couple months.... I don't mean to ask stupid questions, but I'm finding it hard to find any examples of using SER to REGISTER to a VoIP provider like Iconnecthere or Broadvoice and forward calls TO/FROM *... All phones will register to Asterisk. Asterisk in turn will register to SER which will pass that registration info on to the SIP Provider... So if someone calls from PSTN it would go PSTN => SIP-PROVIDER => SER => * => My Phone And if I made a call: My Phone => * => SER => SIP-PROVIDER => PSTN The reason I want to do this is because * does not support outbound proxies, round-robin DNS or RTP over TCP... Things I kinda want... If anyone can point me to some examples or maybe help me out I would appreciate it... I've tried WIKI and searching this list, the closest I could come was this post... http://lists.iptel.org/pipermail/serusers/2004-June/008916.html but I can't understand most of it... it looks like he's doing basically what I want to do, but I am unfamiliar with the config file syntax... I've tried reading the manual and the faq, but it dosen't really help when it comes to passing things to/from *... -Thank you for any help you can give Chris

[Serusers] SER process ID
by Masoud Safi 27 Jul '04

27 Jul '04

When I do a "ps -ef | grep ser" I don't get the process if for ser. When I look at the "ser.pid" file, and get the Process ID from it, then try to do a "kill <pid>" for example, it says there is no such process. However, when I send SIP messages to the server, and monitor port 5060 by ngrep, I do see registration response messages go out to my IP phone. Please help. Thanks in advance.

[Serusers] SIP UMS Release
by Kevin English 26 Jul '04

26 Jul '04

Hello Voicemail and IVR Users, The Servpac development team (located Honolulu, Hawaii) would like announce the Alpha version of SipUMS. We ported our old OpenUMS project (http://sourceforge.net/projects/linuxvm) to the work as a SEMS/IVR plugin. Feel free to download it and try it out SipUMS: http://developer.berlios.de/projects/sipums/ In the distribution you will find detailed installation instructions. Make sure that you have set up Perl support for SEMIVR. If you run into any problems installing it, you can subscribe to our mailing list at http://lists.servpac.com and ask questions. We hope that SipUMS can grow and expand in scope and users. The system is pretty flexible and has many IVR features. Out of the box, it has a fully functional voicemail. The web interface is written in perl-CGI but is being ported to php. We look forward to getting feedback from other users in the community on this project. Kevin W. English kevin(a)x5dev.com Software Engineer, Servpac.com 808-356-0034 (w) 808-271-5125 (c)

[Serusers] using SER as a frontend to asterisk SIP/PSTN gateways?
by Roy Sigurd Karlsbakk 26 Jul '04

26 Jul '04

hi I've been told to setup a 48-PRI SIP/PSTN gateway system, and want to do this as follows: 1 SER server proxying all incoming SIP connections 12 asterisk servers with 4 E1 PRIs each doing the actual SIP/PSTN gatewaying 1 database server for number routing, call details and authentication info Questions: - How can I setup SER to forward up to 120 calls per asterisk node before switching to another one? does SER keep a list of open RTP connections to the box forwarded to? - Can multiple SER boxes be used for failover or load balancing? thanks roy
