500 Address Resolution Failed

Probably the DNS address can not be resolved. Keep in mind that SIP also used NAPTR and SRV records. On log level 8 you can see how the PBX step-by-step resolves addresses.

 

Managed to get around that but now getting a 408 request timed out error?

Well, that tell you that the PBX was able to determine the destination, but there was no valid response coming back...

 

Check out the logging: http://wiki.pbxnsip.com/index.php/Log_Setup. There you can see how to turn on the logging and see what SIP messages the PBX sends and receives.

Not seeing a great deal in the logs. have pasted below could this be an issue caused by NAT?

Why are you using port 5061? I see that port 5060 should be used.

 

ibm# host -t NAPTR sipgate.co.uk

sipgate.co.uk has no NAPTR record

ibm# host -t SRV _sips._tcp.sipgate.co.uk

Host _sips._tcp.sipgate.co.uk not found: 3(NXDOMAIN)

ibm# host -t SRV _sip._tcp.sipgate.co.uk

Host _sip._tcp.sipgate.co.uk not found: 3(NXDOMAIN)

ibm# host -t SRV _sip._udp.sipgate.co.uk

_sip._udp.sipgate.co.uk has SRV record 0 0 5060 sipgate.co.uk.

ibm# host sipgate.co.uk

sipgate.co.uk has address 217.10.79.23

sipgate.co.uk mail is handled by 10 mail-in.netzquadrat.de.
