My voip provider has told me that virgin needs to disable SIP ALG. There is no setting in my router to do this. Customer service are telling me I need to pay £9.99 to speak to the right team to sort this. Sounds ridiculous!! Can someone please get in touch about this?
I assume the issue is your VOIP phone is not connecting to the VOIP provider.
We have operated three SIPGATE VOIP phone numbers on Virgin Media since 2017,
there is no SIP ALG on the VM Hub's Ports 5060.
If you wish to verify this use sip-alg-detector.exe a DOS program from
https://support.kinectcommunications.com/sip-alg-dectector
Run it in a DOS window, don't double click because it will execute and vanish.
If you are new to Virgin Media, the most likely issue is that Parental Controls are enabled by default on new accounts, this can block VOIP, Wi-Fi Calling & Whatsapp etc etc.
Login to the Virgin Media account and disable Parental Controls.
Do check that your VOIP phones or ATAs are using the VM Hub IP range 192.168.0.xxx.
If the phones were previously on static IPs in the range 192.168.1.xxx for say a BT Router that would not work with the VM Hub.
Happy to discuss further if needed.
Perhaps the OP does not have a VOIP issue after all !
