I m new to Asterisk. My team have setup the 15.6.1 version on a CentOS 7 VM with real IP.
We have created two extensions. We are using Bria software for the extensions as SIP phone.
But the problem is when calls come in it rings. We can receive the calls.
But there is no voice on either side.
I have checked the speaker/mic settings and all are working fine.
I found that it could be a problem for NAT which is taken care by the VM provider.
Any idea what else might be causing the issue?
I would appreciate a little descriptive help.
Thanks in advance.
