Hi,

I'm trying to make the endpoint register automatically without a need to provide the GK ip.

 

I set the following SRV records and verified them.

_h323ls._udp.xyz.com

_h323cs._tcp.xyz.com

 

C:\Users\shabana>nslookup -query=SRV _h323ls._udp.xyz.com
Server:  UnKnown
Address:  192.168.1.46

DNS request timed out.
    timeout was 2 seconds.
_h323ls._udp.xyz.com SRV service location:
          priority       = 0
          weight         = 1
          port           = 1719
          svr hostname   = 192.168.1.252

C:\Users\shabana>nslookup -query=SRV _h323cs._tcp.xyz.com
Server:  UnKnown
Address:  192.168.1.46

DNS request timed out.
    timeout was 2 seconds.
_h323cs._tcp.xyz.com SRV service location:
          priority       = 0
          weight         = 100
          port           = 1720
          svr hostname   = 192.168.1.252

 

the group 500 use the same dns server and the domain set xyz.com in the Lan properties.

 

when I set the gatekeeper to auto the registration fails. so I tried to capture the traffic using wireshark but it seems that the group series is not doing the SRV lookup, it is trying to sent a registration request to broadcast address 224.0.1.41 as below without receiving any response.

 

332    8.120352    192.168.1.8    224.0.1.41    H.225.0    140    RAS: gatekeeperRequest

 

the group 500 software: 6.2

gatekeeper: VBP 7301 in embedded GK mode.

 

how can we solve this issue? why does the group 500 is not sending SRV lookup to _h323ls._udp.xyz.com?
