Re: PBX

I made a lot of tests - on a separate email will report the results of using browsers as VoIP Pronto clients, which I guess is not a priority for most users of CGPro’s VoIP functionality.

I managed to get audio in the calls by removing the WAN IP from CGPro’s config.
Which shouldn’t be the case and surely will bring some trouble on other fronts.
Details below, please what am I doing wrong?

Now I do have audio between two Cisco phones, between a GoIP device and a Cisco phone, and between an iOS Pronto client and a Cisco phone. The only thing I had to do was remove the “WAN IP” from CGPro’s settings. So, question is then, why did I have to do that?

My network configs are as follows:
- One CGPro server with two ethernet interfaces: one to a switch that manages the data network (email, etc.) and one to a PoE switch that handles the VoIP network (a few Cisco phones, one GoIP GSM Gateway, one Grandstream PSTN gateway)
- each switch is also connected to each port of a Mikrotik router that NATs the internet
- two network address ranges: 10.10.10.x (data) and 192.168.15.x (VoIP) ; for each network there is a server address and a gateway address.
- so the CGPro server has one address on each interfase, belonging to each network. It has 10.10.10.5 and 192.168.15.5 ; and each also has it’s associated DNS and Gateway address, which in fact point to the same router which has an address on each port.

In the Network configs of CGPro webadmin, under settings->network->LAN IP both ranges have been included; they’ve also been included in the Client IPs tab although supposedly the “Process LAN IP Addresses as Clients” tab should handle that.
And the WAN IP was filled with the actual public (internet) IP of which the router sends everything to the CGPro server (a DMZ).
And “server LAN IP Address” popup is set to “Disabled"

SO HERE COMES THE WEIRD THING
- as long as there’s a WAN address, CGPro seems to tell the SIP clients to go send their audio packets there; calls connect but no audio.
- if I remove the WAN address, suddenly it all works
- if I change the “server LAN IP Address” popup to the server’s address on the VoIP network, calls don’t even connect.

So why does CGPro, when the WAN IP address is filled, sends the SIP clients on a wild goose chase pointing them to the internet? both ends of the call have registered from local addresses, with account and password… and yes, those addresses are NATed whenever a call comes from/to the internet, but not when calling each other within the local network…

the relevant portion of the logs, where it’s telling the clients to send the audio to the WAN, seems to be here:
