Hi All,
I am doing some testing to determine whether or not the 4331 router will work in our smaller scale voip deployments. We currently use a 2911 router with a pvdm3-64 and a 4 port fxo card. In the 4331 we have a spare pvdm4-256 with a nim-2fxo for the pstn connectivity using POTS lines. The issue I am running into is with the commands below. The router is running isr4300-universalk9.03.14.00.S.155-1.S-std. It will take the profile and the associate command lines but kick back an error on the codec lines and when I go to allocate the maximum sessions it tells me there are none available.
I have inbound and outbound calling working but I cannot get conferencing or transcoding to work due to no DSP resources being available. It is my understanding that on the Cisco ISR 4K platform they changed the way that the DSP resources are used. We also tested using a T1 card and a PRI with a pvdm4-128 mounted onto the card. This worked perfectly, but I cannot get the nim-2fxo to work. This will cause us to not be able to deploy our smaller sites that only require a few POTS line and cannot justify the expense of a PRI.
