When you click on a contact in SERweb, it invokes a "click to dial" script which uses t_uac_dlg FIFO command. The error you are getting is the one SER returns for this FIFO call when it can't resolve the SIP domain of the user you are calling. SER requires that the SIP domain is either resolvable in DNS, the /etc/hosts file, or a DNS SRV entry to know how to route these calls, EVEN if the SIP domain is ITSELF. In this case you're not calling SER and walking through the .cfg file, etc. SER is simply acting as a UA and trying to call the user@sipdomain without looking in locations, checking any uri=myself type rules, etc (the config script isn't run at all until SER calls itself by sending the packet to itself, which require then name resolution). You can probably think of it as simply calling t_relay() directly. If you use an IP address, it works fine, but of course SERweb stuff you click on for CTD usually arn't IP addresses. Define the SIP domain you are calling in /etc/hosts, DNS, or define a DNS SRV message for the SIP domain, it will work with a textual SIP address. I suggest using the DNS SRV entry, since defining your domain in hosts or DNS can cause BAD problems with other functions in your domain, such as mail delivery, or if you have your domain pointed to your WWW server so that users can type just the domain name w/o "www" and get to your web site (common practice). There may be other solutions too, such as including Route headers in the INVITE message, but I don't know if t_uac_dlg pays attention to these, or how these are properly formed, etc. iptel guys ? - Jim CURRO_DOMINGUEZ wrote: -- +---------------------------------------------------------------------------+ | 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 ?
