Setup a Yealink W60B and W53H combo at home connected to Zyxel MWEB fibre router which works perfectly.
Installed it at our clubhouse via Huawei B525 LTE router, outgoing calls are fine but won't accept incoming calls.
I have disabled SIP - ALG, also tried in security settings to create Yealink IP phone port 6050 TCP etc.
Is this a router or Telkom problem?.
Was wondering if something is disabled because Telkom only offers "voice" to businesses.
 
LTE has strict NATTING

So even if you open SIP ports on the LITE router it wont do anything. (Double NAT)

Am not sure if Telkom have an unrestricted APN. If they do then it should work.

Maybe someone else on the forums can advise on Telkoms APN
 
Telkom has an unrestricted apn called unrestricted. Once you switch to it, you should receive an ip address in the 41.x.x.x. range.

To set it up on the router:
- Logon to the router and navigate to 'Profile management'
- Create a new apn and set the Profile name and APN values to 'unrestricted' (without quotes)
- Set the new apn as the default.

You can also setup port forwarding for the SIP and RTP ports under the Virtual Server settings if necessary.
 
You do not need to open any incoming ports or port forwarding for VOIP to work. Your VOIP phone is a client, not a server, and it connects to your VOIP provider's server outside your network.
 
Have changed APN to "unsecured", still only works with outgoing calls. @deweyzeph that is my understanding but am now plucking at straws.

Whenever I've had problems with my VoIP phone working with a new router it's almost always to do with the SIP ALG settings. Try testing with it enabled and then disabled. I've seen cases where it works with it either enabled or disabled depending on the VoIP provider, VoIP hardware and router model.

I think it was supposed to be unrestricted - big difference.
That's correct, I meant "unrestricted"

How long did Axx take to activate your service? I applied Thursday but still only a tel no.

SIP - ALG was disabled, opened ports 5060-5061 virtual server.
 
More drama, started ringing incessantly with calls from short numbers. Brought it home and it worked perfectly.
Going to disable Direct IP call and enable SIP trust and see if it goes the job. :mad:

This typically is an example of someone trying to directly relay calls from the IP phone. You can try to close down 5060-5061 and open only the RTP ports, this allows for the VOIP stream to happen but not for the Session Initiation. The RTP ports or UDP 10000-20000. If that doesn't work and you must have SIP opened then the SIP Trust as per what you mentioned may work fine.
 
Disable Direct IP call and enable SIP trust worked :)
