How to create a DNS SRV record on Cisco CNR 8.1.2.1?

[Richard00]

I am trying to create a SRV RR but I get "A general error has occurred". Few years ago, I was able to do it on another CNR but now I don't remember the right format to used.

• On Name field = sip
• TTL = default value of -1
• Type = SRV
• Data = I have tried with different options:
  • _sip._udp.myexample.com IN SRV 1 1 5060 asterisk.myexample.com
  • _sip._udp.myexample.com. IN SRV 1 1 5060 asterisk.myexample.com.
  • With/without "IN". 
  • with/without "SRV"

But every time I get the error. 

What value should I put on Data field to create a SRV RR?

This is the UC / Collaboration area, might want to move this to a relevant area.

Hello,

as far as I recall, this:

_sip._udp.myexample.com. IN SRV 1 1 5060 asterisk.myexample.com.

is definitely the correct syntax. The first '1' is the priority, the second '1' is the weight. Try:

_sip._udp.myexample.com. IN SRV 1 100 5060 asterisk.myexample.com.

or

_sip._udp.myexample.com. IN SRV 0 100 5060 asterisk.myexample.com.

Actually, this is the correct way:

• Name = _sip._udp.somename
• TTL = a TTL value
• Type = SRV
• Data = 1 100 5060 asterisk.myexample.com. (Or whatever priority/weight/port/target value)
