[Serusers] problem with failure_route

Hello, I do have the following in ser.cfg: ------------------------ failure_route[1] { log(1, "Entering failure_route(1)"); revert_uri(); log(1, "reverted"); rewritehostport("xxx.xxx.xxx.xxx:5060"); log(1, "rewritten"); append_branch(); log(1, "appended"); t_relay_to_udp("xxx.xxx.xxx.xxx", "5060"); log(1, "relayed"); log(1, "Exiting failure_route(1)"); break; } ------------------------ It is called from … [View More]

[Serusers] Associating a contact address with a location
by Aisling 01 Jul '05

01 Jul '05

Hi, Sorry to resubmit on much the same topic as before (Portal for forking call to preferred end device-sequential ringing) but I was wondering if anyone had any further ideas on how to associate a particular contact address with a location. i.e. a user can choose that their preferred location is their desktop phone and I need to devise some way to know that a particular contact address is associated with the desktop phone. I was thinking the user must either enter the device ip addresses … [View More]manually so I can search the contact based on IP address (This sucks in terms of NAT, scalability and losing mobility over networks) OR I could perhaps stipulate that a user cannot have two of the same device e.g. cant have two BT100 hardphones and I could search the location table based on model. I think either of these options aren't great....Which is why I was wondering if anyone had any better ideas? Many Thanks, Aisling. p.s. I currently retrieve the users contact address and q value via a web interface using the serctl fifo interface. -----Original Message----- From: Bogdan-Andrei Iancu [mailto:bogdan@voice-system.ro] Sent: 22 June 2005 12:45 To: Aisling Cc: 'Greger V. Teigre'; jh(a)tutpro.com Subject: Re: [Serusers]CPL - Portal for forking call to preferredenddevice-sequential ringing Hi Aisling, There are many ways to implement serial forking - like using CPL, LCR or AVPOPS. But the main idea (if I getting right from your initial email) is to allow the user to order his contacts for the same account (like account userx that have contact_pda_x, contact_PC_x, contact_office_x, etc). So you have all this contacts in user location, you have several mechanism for serial forking, but you are missing the link - to get the contacts from user location and to feed any of the serial forking mechanism. This is the big problem. even if you use CPL, you need to place in each location node the contacts (and not the AOR) of the user, contacts which are dynamically stored only in user location. what you are describing below can be possible only if you a user (as person) has different sip accounts (SIP users) for each of his devices. Other way I don't see how you can place in the CPL script the "phone1" and "phone2" addresses. and just to answer you to the CPL- related questions (from implementation point of view): - each user can have only one script - if you load a new script, the previous one will be lost (overwritten). If you can different services via CPL (like screening and no-answer), you need to mix them in the same script during provisioning. - if you want to delete a CPL script via FIFO, use the REMOVE_CPL command: serctl fifo REMOVE_CPL user@domain regards, bogdan Aisling wrote: >Hello, > >Many thanks for the ideas so far. >I looked at CPL Greger and I think that provides a very simple solution >to this - a simple Call forward on no answer script. > >I have an included an example that I came across below.

Hi! The 0.9.4 source tarballs at http://openser.org/pub/openser/0.9.4/src/ still have the postgres-usrloc bug. (I knew I should have used CVS) I suggest that they will be updated automatically, or removed. regards, klaus

Hi everyone! I have set up a ser as an outbound proxy with nathelper+rtpproxy. This is my set up IPphone1 --> nat router --> outbound proxy(OP) --> softswitch(SS) IPphone2 --> with the OP and SS in public. The IPphones are behind the same NAT and both configured to the same OP. I am only testing against this softswitch from some vendor so i don't have any control over it. And I used the sample nathelper.cfg from the CVS to get started. Registration went … [View More]

[Serusers] Asterisk as PSTN Gateway
by Samy Antoun 30 Jun '05

30 Jun '05

I have Asterisk and SER at the same computer with 2 different listening ports, the goal is to accomplish this scenario: - SER acts as a NAT transversal gateway with Mediaproxy - Asterisk acts as PBX, PSTN Gateway and Voicemail server That means that ALL the authentications, PBX functions and switching are handled by Asterisk. I donât know how to do this, all I can do now is: - Create users with DB authentication at SER, these users can successfully register and place calls to each other … [View More]

[Serusers] ser and directing traffic to diff sip blocks in asterisk
by Iqbal 30 Jun '05

Hi Is there a way of getting ser to send messages to asterisk but to match different blocks in sip.conf in asterisk In sip.conf asterisk seems to match on a) the username (From:) b) the ip address c) default What i want to do is to based upon certain matches in ser to direct the INVITE to a particular block in sip.conf, from where I can then match to a diff contect in extensions.conf. If this is not possible can I have a variable name for context based upon username of something like that.… [View More]
