Cannot register using DNS SRV ysing UCS 4.0.1 firmware

Hello, 

 

We are starting to use two new asterisk servers that are setup with a DNS SRV record so that they can fail over if necessary.  From the 4.1 manual, 

 

DNS SIP Server Name Resolution
If a DNS name is given for a proxy/registrar address, the IP address(es) associated with that
name will be discovered as specified in RFC 3263. If a port is given, the only lookup will be an A
record. If no port is given, NAPTR and SRV records will be tried, before falling back on A
records if NAPTR and SRV records return no results. If no port is given, and none is found
through DNS, 5060 will be used. If the registration type is Transport Layer Security (TLS), 5061
will be used as the port number. See RFC 3263 for an example.

 

In my per phone config, i have   reg.1.server.1.address=".*****.net" - but the phone is not registering, and The log showed me that I'm getting an A record, even though i did not specify a port - Should i be using another value than reg.1.server.1.address?

Hello NatelBroadband,

In that case UCS 4.1.7 is the latest Version.

 

There is also UCS 5.0.2 to be considered.

Right, but What about using SRV records in the phone config?

Re: Cannot register using DNS SRV ysing UCS 4.0.1 firmware

Hello, 

 

i did, read the admin guide,and i copied it into my first post in this thread.  That is why i started the thread, because the guide is not clear enough with an implementation example.  We have two servers, that are linked in a SRV record.  

 

How do we reference them correctly in the per phone config?

 

Do we use reg.1.server.1 and reg.1.server.2 or refer to the SRV record directly?

 

Thank you

Hello Natel,

 

You can use either configuration. 1 server, using the SRV record, or server.1 and server.2, using the IPs/hostname of the servers.

 

In our environment we use server.1 and server.2, however this means the phones maintain active registrations to both servers, they don't fail from one to the other, so this is something you need to consider, in regards to how your servers work.
