We have done this before but we had to do go back to 10000-20000. This
should have not caused a problem but, we had a lot of call quality problems
when we had it set to 10000-10500 and only had 7 ext on the server.

Just my two cents

Subject: [Asterisk-Users] Narrowing RTP port range

Hello everyone..

I'm trying to lock down my asterisk install as much as possible and I
keep reading about people saying 'you can narrow the range of ports in
rtp.con' (by default it's from 10000 to 20000 I think).

My question is this - how much can I narrow it down?  Can I narrow it to
10 ports, or can the ports not be reused for additional conversations?

I guess what I'm asking is - does the number of ports in the range have
anything to do with the number of simultaneous connections or anything
like that?

Thanks again,

tf.
