(OP)
Hi guys,

I have a strange issue where I have a phone connected via MRG to the main site where the NS700 is installed.

There is a SOnicwall at the remote site.

When make call there is 1 way speech

If I take the Sonicwall out and put a Draytek in, it all works fine.

So the Soincwall is blocking speech on the rmote phones.

Any guides that I have read are to do with the ports at the System side firewall and not the remote site firewall.

Struggling with this so any help will be very much appreciated.

RE: Panasonic NS700 MRG

What type phone MGCP or SIP do you use?

RE: Panasonic NS700 MRG

Make sure all sip helpers and alg’s are disabled on the firewall
