Describe the bug
When adding multiple ip addresses in the fields "Hosts to allow registration", "Hosts to allow SIP" and / or "Hosts to allow SIP" it will only accept 1 ip address multiple addresses are not accepted in the gui, so:
192.168.9.125/32 is accepted and 192.168.9.125/32,192.168.9.130/32 is not accepted.
The help says: Here you specify the devices allowed to do SIP connections to siproxd (internal and external). Format is CSV without spaces and CIDR, like 192.168.0.0/24,10.0.0.0/8.
So according to the help and the siproxd documentation it should be possible.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Services\Siproxd'
2. Click on 'General'
3. Scroll down to 'Hosts to allow registration' or 'Hosts to allow SIP' or 'Hosts to allow SIP'
4. See error

Expected behavior
Expect to input multiple IP-addresses/Networks according CSV format without spaces and CIDR, like 192.168.0.0/24,10.0.0.0/8..
