[Serusers] SER routing fails with two levels of alias indirection w/o hosts entry pointing SIP domain to itself...

by Jim Burwell

Hi, A client of mine has encountered a problem with SER. When he has aliases which point to other aliases, SER fails to route a call UNLESS the SIP domain of the callee has an /etc/hosts entry associated with it (or, presumably, a DNS A record for the domain, or a DNS SRV record for SIP inside that domain). For example: ser.cfg has line: alias="domain.com" Callee is "alias1(a)domain.com" SER user alias "alias1(a)domain.com" -> "sip:alias2@domain.com" -> "sip:user@domain.com" SER usrloc entry exists for "user(a)domain.com" -> "sip:user@[IP-of-user's-phone]" /etc/hosts file has entry in the form of: 1.2.3.4 siprouter siprouter.domain.com domain.com CALL WORKS However, change /etc/host file entry to: 1.2.3.4 siprouter siprouter.domain.com (remove alias for whole domain) CALL FAILS Other, more simple SER user aliases WORK in BOTH scenereos: SER user alias "somealias(a)domain.com" -> "sip:someuser@domain.com" SER usrloc exists for "someuser(a)domain.com" -> "sip:someuser@[IP-of-user's-phone]" CALL WORKS This is whether the "domain.com" /etc/hosts alias exists or not. So, SER appears to NEED to resolve an IP address for the SIP domain to do two (and above) levels of alias indirection. It's almost as if the resolution of aliases isn't recursive or something (seeing how single-level aliases work, and it doesn't try to resolve an IP to "call out" to another SIP router). Note, that "ser.cfg" DOES have a line alias="domain.com", so SER should know that it is responsible for this SIP domain. It appears that SER is trying to make a network call to this SIP domain before it even begins processing the ser.cfg script, where it would match the if(uri == myself) condition because of the "alias=" lines. Perhaps a heuristic needs to be put in somewhere to check the condition "callee_domain == myself" before SER goes through the trouble of trying to resolve the callee domain when it will just point back at itself ? This problem reminds me of the one I ran into earlier with the t_uac_dlg() FIFO call used by the click-to-dial scripts. This also had the problem where SER would try to resolve its own SIP domain before checking if SIP_DOMAIN == myself. The quick and dirty fix was to add a /etc/hosts alias (as illustrated above), but this has the unwanted effect of breaking sendmail mail routing, requiring an ugly rewriting rule hack to "fix" the problem (sendmail thinks myself == mail domain, and recipients w/ @domain.com addresses are local users). The "good" fix is to use a DNS SRV entry (at least I hope this would fix both SER problems mentioned here). But, should SER really be doing these name resolution calls in situations like this ? Isn't this inefficient ? It seems like a bug to me :-). It seems to me that SER should pay attention to the "alias=" lines in all phases of calee routing, with the exception of when the calee's SIP address is resolved down to userloc entry pointing it to another SIP device. Perhaps my concept of the purpose/scope of a SIP domain is wrong ? I assume that a SIP server, or group of servers with identical configurations/databases (for load balancing) is "authoritative" for a domain, and unless an alias or usrloc entry directs the call to a different SIP UA or router via IP or a different SIP [sub]domain for further processing, it should presume it has all information to resolve this call fully itself, and recurse onto itself to resolve any names inside its own domain. Basically, the DNS model for domain authority. - Jim -- +---------------------------------------------------------------------------+ | Jim Burwell - Sr. Systems/Network/Security Engineer, JSBC | +---------------------------------------------------------------------------+ | "I never let my schooling get in the way of my education." - Mark Twain | | "UNIX was never designed to keep people from doing stupid things, because | | that policy would also keep them from doing clever things." - Doug Gwyn | | "Cool is only three letters away from Fool" - Mike Muir, Suicyco | | "..Government in its best state is but a necessary evil; in its worst | | state an intolerable one.." - Thomas Paine, "Common Sense" (1776) | +---------------------------------------------------------------------------+ | Email: jimb(a)jsbc.cc ICQ UIN: 1695089 | +---------------------------------------------------------------------------+ | Reply problems ?

[Serusers] No email address - Error from SEMS

by Darren Nay

Hello All, We've been wrestling with SERS and SEMS config for the past week, and I think we almost have it, but we are still getting a few errors working with SEMS and the voicemail piece. The main problem right now is that we are getting this error returned from SEMS when the call is redirected to voicemail. Nov 26 17:40:58 jupiter Sems[2413]: Error: 404 voicemail: no email address for user <8641234567> I've checked the record in the "subscriber" table for this user in the "ser" database and the email address is there. I thought, at first, that this might be caused by ser being unable to connect to the mysql database (it's on a seperate server) .. I've verified that it is connecting now though. Anyone have any ideas why we might be getting this error? I have attached our ser.cfg file for the voicemail ser router below (in case it helps). Any help would be very much appreciated.

[Serusers] latest ans_machine and ser-0.8.12

by - zaki -

Hi, I got ser-0.8.12, and successfully installed. However, sems-0.1.0 does not work with ser-0.8.12 'cause of protocol differencies. So I accessed to http://developer.berlios.de/cvs/?group_id=653 to get latest sems(ans_machine) code, but anonymous access to CVS tree failed. And latest tarball on web-based CVS doesn't work well 'cause of "undefined symbol". Could anyone please let me know regarding release schedule of sems(ans_machine) stable version which can work with ser-0.8.12 without problem?

[Serusers] exec_dset() error checking?

by Alan Crosswell

The following code fragment causes a SER error rather than returning a detectable failure: if (!exec_dset("/etc/ser/sipldap")) { sl_send_reply("404", "Not Found"); break; } Nov 26 15:26:32 ren /usr/sbin/ser[30834]: INFO: SIGCHLD received: we do not worry about grand-children Nov 26 15:26:32 ren /usr/sbin/ser[30834]: ERROR:exec_str: no uri from /etc/ser/sipldap sip:wwww@columbia.edu The script prints a URI and does exit 0 on success. It prints nothing and does exit 1 on failure. However, this does not appear to be seen as a failure by ser but rather a runtime error. What am I doing wrong? /a PS: The documentation for exec_dset() misspells it as exec_dst() in http://iptel.org/ser/doc/modules/html/exec.html

[Serusers] Memory errors

by Darren Nay

Hey all, I am in the process of installing SER for the first time and doing some initial configuration and testing. However, I am having some problems and hoping that someone on this list may have seen this before and can point me in the right direction for a solution. I have downloaded the Solaris9 Sparc64 package of SER version 0.8.11. It's been installed and starts up and runs okay. I've also configured it to use MySQL for authentication, and setup serweb to integrate with the MySQL server as well. So far so good.. everything seems to work. I can add a user using "serctl" and then login with that user via "serweb". very cool! The problem occurs when I try to connect to the SER server from my SIP phone. I get the following errors: Nov 20 13:11:02 ultra60 ./ser[3942]: ERROR: build_req_buf_from_sip_req: out of memory Nov 20 13:11:02 ultra60 ./ser[3942]: ERROR: print_uac_request: no pkg_mem Nov 20 13:11:02 ultra60 ./ser[3942]: ERROR: t_forward_nonack: failure to add branches Nov 20 13:11:32 ultra60 ./ser[3942]: ERROR: build_req_buf_from_sip_req: out of memory Nov 20 13:11:32 ultra60 ./ser[3942]: ERROR: print_uac_request: no pkg_mem Nov 20 13:11:32 ultra60 ./ser[3942]: ERROR: t_forward_nonack: failure to add branches Has anyone seen this in the past? Or know of any reason that this might happen? Maybe even a possible solution? :) Any help would be appreciated. Thanks!! Darren Nay - dnay(a)libertyisp.com
