[asterisk-users] PAP2T provisioning via SRV record?

[Mike Diehl]

Well, I ran a simple test by trying to configure the second port to use the DNS SRV record, as described below.

Here is what I have: (sanitized)
==========================================================
<Proxy_2_> diehlnet.com </Proxy_2_>
<Outbound_Proxy_2_> fqdn </Outbound_Proxy_2_>
<Display_Name_2_ ua="na">username</Display_Name_2_>
<User_ID_2_ ua="na">username</User_ID_2_>
<Password_2_ ua="na">password</Password_2_>
<Use_Auth_ID_2_ ua="na">Yes</Use_Auth_ID_2_>
<Auth_ID_2_ ua="na">username</Auth_ID_2_>
<Use_DNS_SRV_2_>yes</Use_DNS_SRV_2_>
==========================================================

With this configuration, the second port does NOT register.  A sniffer trace on the inside interface of my router gives me some clues, though:

23:54:34.906089 IP 10.0.1.87.60198 > 208.67.222.222.53:  1+ A? diehlnet.com. (30)
23:54:35.102409 IP 208.67.222.222.53 > 10.0.1.87.60198:  1 1/0/0 A 173.10.242.193 (46)
23:54:35.104484 IP 10.0.1.87.5061 > 173.10.242.193.5060: UDP, length: 527
23:54:35.104553 IP 173.10.242.193 > 10.0.1.87: icmp 556: 173.10.242.193 udp port 5060 unreachable

It seems that the device is still looking for an A record for diehlnet.com, which does exist.  It should be looking for the SRV record.

What am I missing?

Mike.
