Hi everyone.

CONFIG (Version=12.0)

The phones are 7945s, and both are registered and can call each other just fine, no issue good audio.

ephone 2

> Sorry for not being clear, for the call statistics, you can check on the phone > settings. Basically, I want to see if there is any routing or ip addressing issues, you would see only outgoing packet counts going up and no incoming packets along with type of codecs being used.

Also, the helpful would be use the following commands:
1. "dspfarm dsp active" which would show the active dsps (conference etc) eg as shown below, where no dsp chips are being used

CUBE-01#sh dspfarm dsp active
SLOT DSP VERSION STATUS CHNL USE TYPE RSC_ID BRIDGE_ID PKTS_TXED PKTS_RX ED

2. show call active voice compact , which show the calls that are currently active and their end points.

OK I checked the call statistics on the phone, while they are in the conference there are no recv. but lots of sent. I don't think it it router because both phones are on the same CME, and can call each other.

 

Router#sh dspfarm dsp active
