No Voice traffic through Preferred Mobile but there is on Avaya Communicator??

[Josh.]

I have a customer which has power user licences.

They use both Avaya Communicator and the preferred mobile app through a Cisco AnyConnect VPN.

The softphone works fine remotely with speech but there is no speech either way through the mobile app.

Any idea what could be causing this??

TIA,

 

[Josh.]

Please can someone shed some light on what could be causing this?

I have been pulling my hair out for days!!

TIA,

The IPO is on 9.1.9.0 build 182 and One X server is 9.1.10.0 build 192.

Is that any help?

Are you using a split DNS for the mobile side of things? Ports open on the firewall?

 

[Josh.]

All the correct ports are open on the firewall. I may be wrong but I thought split dns was only required if they needed to use the app internally and externally. As they are only using it over a VPN and not through the subdomains I didn't think this would be required.

TIA,

SIP remote worker enabled?

And yes, the IP Office can detect a NAT connection.

Gunpoint 132 and Bush.Cover's code three

Avaya communicator extension is the same to Avaya one-x mobile extension? Did you check if SIP ALG is disabled on the firewall?
