Whether digium & Astensk support dynamic DNS


#1

Hi all
I don’t know digium’s product can use ADSL (dynamic DNS) for voip or not ?

Thanks


#2

it depends. if you’re having your * box register with a provider, and you use IAX, it is not a problem. if you want to use IAX trunking with a provider, that’s a problem…


#3

I’m sorry, I’m newbie, Can you tell me more clear. IAX is what.

Thanks


#4

IAX is the protocol invented for asterisk. it’s MUCH more NAT friendly than SIP, since all traffic goes through one UDP port. get a basic book on asterisk and a lot of this will be much clearer…


#5

If I use Sip not IAX, it depend on what thing


#6

SIP requires SIP packets (one set of ports) for the control packets, the actual VOIP travel in RTP packets which require a ton of ports to be opened. Other complications too.
