3CX system, ver 9.
Running for about 1 year
Callcenteric for a VOIP provider
All calls work great, inbound and outbound
Free system
dynamic IP address at location of the 3CX system
I have a dyndns account set up and this works fine
I want to set up Direct SIP calls, inbound and outbound
I set up a free account at iptel.org
I have enabled Direct SIP calls in Settings - advanced
I have set up my internal extension (104) with a SIP ID in extensions - 104 - other
I also use a DR
In settings advanced I have set the Local SIP Domain as office.local (this is the domain name for the system the 3CX server runs on)
If I look up my current IP address (where the server is)
from a softphone set up for the iptel.org account I can call [email protected]
This call gets right through to the DR, no problem.
I can also call the iptel.org phone from my 3CX extension as a SIP call - [email protected]
When I try to call the 3CX extension from the iptel.org phone using [email protected] it does not go through
I get the following in the log:
16:10:59.265 [CM500002]: Unidentified incoming call. Review INVITE and adjust source identification:

X-RTP-Proxy: YES
yyyyy = user name at my iptel account
xxxxxx = my dyndns account name
Now I suspect that it all has to do with A records and srv records (accoring to the blog post I read before trying to set this up).
If that is the case, I do have a domain name registered with godaddy that I could use and adjust the A record to my xxxxx.dyndns.org account but i do not know if an A record would accept an FQDN instead of an IP Address.
If it would, I could set the srv record for that domain (registered at godaddy) to point to my dyndns address as well.
Seems I am close in that I can call my 3CX system using a direct SIP address if I use the IP address of my system but I don't see how I can expect people to try to look that up before calling with a direct SIP call. I would think it should work with my dyndns address. If that is not the case I can change the settings in my spare domain at godaddy but i would need to know what to change those to.
Can anyone help? I am got an expert in this area so if you do have a suggestion, please put it in easy to understand directions.
Thanks,
Steve
