    Is it possible to limit the range of ports that a sip-ua can assign/allocate for its RTP audio streams? Been looking through a lot of SIP and Telephony documentation on to no avail. Instead of just using the default UDP 16384 – 32767 I’d like to limit the allowed RTP ports to a smaller range of about 1000 ports. Any advice is appreciated. Thanks!

      Hello, I am wondering if you received an answer to your question? I am also trying to limit te port range used by RTP. Thanks!
