NAT Transversal - Expand X_PublicIPAddress to work from a URL

[N2VWZ]

Expand X_PublicIPAddress to work with an IP Name such as xxxxx.dyndns.org in addition to an IP address. (or add a new X_PublicIPName parameter)

My Obihai ATA operates behind a NAT.  I presently supply my WAN address to X_PublicIPAddress for unregistered direct IP operation.  Any time my IP address changes, I have to manually update the ATA with the new IP.

My router updates the Domain Name Server automatically whenever an IP address change takes place.  Manual IP address updates could be eliminated if the OBihai ATA obtained the WAN IP address directly from the DNS using the provided IP Name.

I second and third this.

If not this, gurus, is there a command that can be used to resolve FQDN

Code Select Expand


FQDN_resolv(myhosthere.afraid.org)

[mayge]

In service provider
ITSP
SIP
X_PublicIPAddress

I jammed in a dDNS FQDN.  

How can I determine it's not working as expected?  (other than syslog)

[I understand FQDN is _not_ URL]


examples:

your-awesome.domain.tld
obijoy.us.to

How can I determine it's not working as expected?  (other than syslog)

I just tested this (fqdn in X_PublicIPAddress) with an OBi110 and 1.3.0.2774, with X_DiscoverPublicAddress disabled.  I made a test call via a SIP switch that does not proxy audio (audio travels directly from the carrier to the phone).  Though the other party could hear me speaking, I could not hear them (presumably because the carrier was trying to send the audio to a non-routable IP address).

When I replaced the fqdn with my IP address (or used X_DiscoverPublicAddress), audio traveled in both directions as expected.

So does the newest firmware support this?
