The "voip" host serves two purposes: 1. The "voip" host alias (well, an A record actually) can point to any server I like, so I can move Asterisk from one server to another without having to publish a new SIP address. 2. The "voip" part makes it (reasonably) clear that it's a SIP address and not an email address. (I know that one address can be used for both, before someone points that out.) Perhaps sip.cursor.biz would be clearer but I just prefer "voip"; It's less specific, so can be used to cover IAX too. I do have SRV records, but I don't publish SIP addresses using domains based upon them. Perhaps I will one day. -- _/ _/ _/_/_/_/ _/_/ _/_/_/ _/_/ _/_/_/ _/_/ _/_/_/_/_/ _/ K e v i n W a l s h _/ _/_/ _/ _/ _/_/ _/_/[EMAIL PROTECTED] _/ _/ _/_/_/_/ _/_/_/_/ _/_/ ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Am I way behind the times or is this precisely *not* how MX and SRV records work? A domain is a domain. A subdomain is just a fancier term for a domain within another domain, and hence not treated differently.

Before you berate others indescriminately remove your foot from your mouth next time so you don't look like as big of an ass next time... OK Son, Since you decided to keep this on the list, I will too. MX and SRV records are used to determine the appropriate handler(s) for: domain.name qualified.domain.name fully.qualified.domain.name more.fully.qualified.domain.name even.more.fully.qualified.domain.name For example, if you had the following in the DNS zone for "domain.name": $ORIGIN NAME. DOMAIN IN NS your.name.server. IN NS your.other.name.server. IN A 10.1.1.1 IN MX 10 your.mail.exchanger. IN MX 20 your.other.mail.exchanger. IN SOA your.name.server. dnsadmin.your.domain.( 200403059 10800 3600 604800 300 ) $ORIGIN DOMAIN.NAME. _sip._udp SRV 10 10 5060 1.your.sipproxy.domain.name. _sip._udp SRV 10 20 5060 2.your.sipproxy.domain.name. _sip._udp SRV 20 10 5060 3.your.sipproxy.domain.name. 1.your.sipproxy IN A 192.168.1.1 2.your.sipproxy IN A 192.168.1.2 3.your.sipproxy IN A 192.168.1.3 Email to [EMAIL PROTECTED] would be processed by "your.mail.exchanger" and not sent to "domain.name" at it's A record. The same goes for email to [EMAIL PROTECTED] In the event that your.mail.exchanger was down, mail would be handled by your.other.mail.exchanger. The purpose of the MX record is to be able to point the SMTP service responsibility at a host OTHER than the FQDN that is being referenced in the email. The same works for SRV records. In the above example, if someone dialed the URL "[EMAIL PROTECTED]", the SIP INVITE would first be sent to either "1.your.sipproxy.domain.name" at 192.168.1.1 or "2.your.sipproxy.domain.name" at 192.168.1.2 (with the first one getting the larger percentage of use based on its weight entry) and not to domain.name at 10.1.1.1. If a sipproxy can't be reached at 192.168.1.1 or 192.168.1.3, the SIP INVITE will be sent to "2.your.sipproxy.domain.name" at 192.168.1.3 based on it's priority as a backup to the first two entries. These records exist so that services can be hosted on machines OTHER than the machine that matches "domain.name". They also allow for fail over in the event of failure of a server or service. It also allows you to point a service at a machine or group of machines without having to give every person a new email address or SIP URL to use. Next benefit: Say you have "big-fat-server.your.domain.name" and every person on the planet uses "[EMAIL PROTECTED]" as your email address and SIP URL. Now, you decide that you want to split the tasks of email and SIP proxy off of "big-fat-server.your.domain.name" and on to their own dedicated servers. With MX and SRV records, this is a matter if simply updating the record appropriate record. Without those records, you now have to tell people that to send you email, they have to use "[EMAIL PROTECTED]" and to call you over VOIP, they have to use "[EMAIL PROTECTED]". Kinda hokey... Huh. That's why we have MX records and SRV records. With these records set up properly, people can both email and call you over VOIP at the same place, "[EMAIL PROTECTED]". Hrm. That seems a bunch easier than remembering what the name to your mailserver and/or sipproxy are, doesn't it. So, decide for yourself folks. Do you want to do it the n00b1e way or do you want to do it right the first time and be done with it? Now.

Re: [Asterisk-Users] DNS SRV records
sip://[EMAIL PROTECTED] works perfectly well... There are many benefits in stability when you use SRV records to find a SIP proxy. However this requires that you have some sort of load balancing between the servers. It was a long time ago anyone mailed [EMAIL PROTECTED] Let's hope we can prove the benefits of using SRV records for finding SIP servers so that * One Asterisk can serve many domains * Two asterisks can serve the same domain, sharing registration databases * Asterisk when calling, can try the second or third server in DNS SRV if the first one fails to answer We are not there yet. Working on it :-) But there are a lot of reasons to turn on DNS srv lookup in sip.conf if you allow outbound dialling on URL or use it in your dial plan. If you do not enable SRV records, you can't phone me. There's no SIP proxy on edvina.net ;-) (And there's no mail server on edvina.net neither. Wish all those spammers tried mailing that instead of reading mx records... ) I don't know if anyone sees being able to phone me as a required feature, but anyway. /O Ps.
