4GData issue

[davea2]

So I have been setting up IX and One-X preferred for a customer.

All works well on both.

On WiFi that is- when we try 4G there is no speech or 1 way speech.
Thinking I had made an error I said no prob it will work - this is mine connected back to our in-house kit - which then did not work - no speech.
(I have to admit I usually use it on WiFi but I have used it on 4G before no problem)

If I look at the invite from my IX making an 'internal' call over 4G I see this INVITE

s=-
c=IN IP4 10.10.123.180
b=TIAS:64000

So, the 10.10.123.180 is an internal address? If I do 'whats my IP' on my phone browser it's 147.78.4.88 which looks fine.

So, my mobile data is being NATed? Used to be fine I'm sure.

This is O2 in the UK. Similar issue with EE

Anyone else having this kind of thing?

Cheers

Seems to work OK on 3

Make sure RTP ports are open in de firewall.

 

[davea2]

Yep, ports are forwarded OK

Easiest way is to see if it works from a WiFi connection out of the office, in that case it's probably the mobile providers network blocking something.

I had this same problem with Rogers LTE network and Avaya Softphones a year ago.
Rogers implémentation of IPv6 that broke the client... they have since fixed this.

The workaround I was using before Rogers fixed the issue, as create a profile for my iPhone that disabled IPv6 and forced IPv4.

I used Apple Profile Manager to create the profile and send to my phone.

So I checked from home last night, so I am not on the office WiFi

On my home WiFi, Equinox works fine
On 4G, no speech.

So I guess my IPO and firewall config is good and it's a mobile data issue?

My phone is set to use IPv4 only (Android)

Please don't share your public IP address... At the same time what way do you have this public IP address of your phone forwarded IP address 147.78.4.88.

What ports? Is it Nat'd or is the firewall just open on those ports?

I know one of our hosted platforms doesn't work on O2 and we had to change to Vodafone, so it couyld be the SIM
