Can someone point me to documentation that explains how to enable (or allow only) V.150.1 on the 4451 IRS Router?
We tried the steps described here: Cisco V.150.1 Minimum Essential Requirements Configuration Guide - Cisco but it does not work: For outgoing calls the router does not offer V.150.1 and for incoming SIP calls it does not accept V.150.1.
Is there some general command to enable V.150.1? How to limit all calls to just V.150.1?
