View Full Version : QCM can't download extensions

04-23-2010, 03:10 AM
I have QCM begind NAT on a remote site connected to Quadro2x behind NAT in office.
Can get quadro to make calls out, but can't receive calls and can't download extensions, or subscribe to line.

Are there any extra ports that need to be open to download extensions or receive calls into QCM in one/other or both of the NATs ?

Been fiddling for ages with this to no avail. Only have 5060-5065 open on TCP and UDP, and 6000-6099 RTP and using stun.
