[Serusers] Problem with 'ser'?
by Kjell Mathiesen 08 Nov '03

08 Nov '03

I downloaded the SIP Express Router on Nov. 6. I run a VoIP course (among others) and want a SIP application to show to my students and I found yours interesting. However, I ran into an obstacle, possibly a problem/bug. The details: System: Red Hat 7.3 Personal on a 200 MHz Intel 'Ser' distr.: 0.8.11 RPM-package for RH 7.3 Clients using Windows Messenger Ser.cfg: As distributed but with option <alias="matell5.no"> added (in front of the 'check_via' option. Works fine. <km(a)matell5.no> and others with the same domain can sign in, contact with other clients established etc. Then I add another domain to 'alias' as in <alias="matell5.no" "f19-21.no">. 'ser' starts OK ('ser start' reports [OK] and /var/log/messages says 'ser' is listening on all IP adresses and both aliases are listed and "ser startup successful"). However, attempted sign-in from clients (with the same domain name as earlier) result in ICMP Destination Unreachable/Port Unreachable (port = 5060) and an attempt to stop 'ser' ('ser stop') reports [Failed] and /var/log/messages says "ser shutdown unsuccessful". I have also tried using two lines for the 'alias' parameters (<alias "matell5.no" \n alias "f19-21.no"> with the same results. Then I remove one 'alias' to return to the successful 'ser.cfg' with only one 'alias', and I get the same IMCP message (Port Unreachable). Then I reboot the computer (no further changes to 'ser.cfg') and the clients can sign in without a hitch. The 'ser' Admin's Guide chapter 6.1 'Core Options' clearly indicates that the 'alias' option can take several domain names. (It actually says hostnames. I tried 'mytikas.matell5.no' which is name of the machine 'ser' is running on but this caused the same erroneous result as above. Changed it back to just the domain name and I could sign in normally again. If I am doing something wrong here (or not doing something I should be doing) I would appreciate if you would tell me. I am relatively new to Linux and Linux applications and sometimes find the documentation difficult to understand. If you want me to supply more information like logs etc. let me know (if this really is a bug you probably will). I'll be happy to do more testing/experimenting. I am not running mysql. I'll try that next. Thanks. (Hope I am sending this to the right place.) Kjell Mathiesen Matell Software AS Fururabben 19 1361 Østerås, Norway Tel.

[Serusers] t_relay_to howto

[Serusers] Multiple sers to mysql & asterish voicemail
by Tristan Colgate 07 Nov '03

07 Nov '03

Hi, I am currently setting up a SER platform and would like to use Asterisk for pstn and voicemail. I have three hosts, one machine has the mysql db and a dns with an enum zone. I then have the main sip registrar/proy and the final box is the asterisk server. My intention is to have an instance of ser running on the asterisk server to verify authentication and check users priviledges for access to the pstn/voicemail and to enforce the Remote Party ID, this will then nat the connection to the asterisk process' sip channel (either running 127,0.0.1. So is this theoretically sound? And can I have the SER proxy and the SER instance on the * both talking to the same mysql DB? -- Tristan Colgate Inux Technologies E-Mail: tristan(a)inuxtech.co.uk Mobile: 07900 690 912

Your server presumably is not configured to handle vfrnd.jp as a served domain and tries to forward to it instead. Apparently, such a domain is not in DNS system. jiri@fox:~$ host vfrnd.jp vfrnd.jp A record not found, server failure jiri@fox:~$ host -t srv _sip._udp.vfrnd.jp _sip._udp.vfrnd.jp SRV record not found, server failure -jiri At 09:21 AM 11/7/2003, Iizuka, Hirotaka, VF-JP wrote: >Content-Class: urn:content-classes:message >Content-Type: multipart/alternative; > boundary="----_=_NextPart_001_01C3A508.14DFEAEA" > >Hello, > >I have a problem with registering to the SER. >I use X-Lite SIP softphone, and when I try to register to the SER, I get following messages; > >(c)2003 Xten Networks Inc.

Re: [Serusers] SER Voicemail
by jaime.gil＠orange.co.uk 07 Nov '03

Jan, Sesha, Ser cannot initiate the transfer by itself, but a simple application talking to the fifo_server in SER can. That's how we worked it out. The drawback is that it only works with IP phones with REFER support (Mitel, Cisco, Pingtel...), not with softclients. Jaime > > (1) How do I set the SER standalone Voicemail config, so that I can reach > Voicemail after 4 rings? You can't reach voicemail after 4 rings because rings are usually generated locally by the caller's phone. You can reach the voicemail after some time, but not measured by number of rings. You can use fr_inv_timer of the tm module for that. > (2) Is SER capable of transferring a call originating from a SIP phone to a > phone on the PBX? If yes, What do I need to set in the configuration? The originating phone must do the transfer, ser can't initiate the transfer. I suppose you mean the transfer of an established call ?
