<div>I'm going to eliminate our CM based software MTPs with n IOS software MTP.</div>
<div> </div>
<div>So, if I configure a trunk with the new MRGL, the trunk will use this to allocate the MTP, correct?<br><br></div>

<div style="WORD-WRAP:break-word">stated alternatively, does any phone colocated with ccm have any issues with vq when using software media resources such as MTP or CFB? stream statistics from the phone (ii, ??, qrt, or cmr records) would help quantify any anomalies in the RTP stream. If your CMR records show consistent poor audio at that remote site then you have a much stronger pointer to the culprit.

<div style="WORD-WRAP:break-word">generally you should deplete mtp resources before voice quality impact. software MTP utilizes network I/O and CPU utilization. we've rarely seen VQ issues caused by sw mtp/cfg but it's not unheard of. if you're using sw media resources then verify the network interface for the CUCM server.

<div>These guys have me starting to doubt myself. CM software MTP wouldn't be causing QoS-like issues, would it? What about if an SIP trunk with "MTP required" checked and we run out of media resources? <br>

<div>I'm not a LAN/Ethernet QoS guru by any means. Our network group has control over QoS and I'm trying to get to the bottom of an issue we've seen routing calls over a sip trunk to a location using a 1gig Ethernet connection on a DWDM ring. No firewall is present. The configuration doesn't seem quite right to me for some reason.</div>
<div> </div>
<div>Basically what we are doing is using an alternate PSTN gateway for toll free traffic until we get additional capacity added to handle the calls. Users report garbled audio and an 'underwater' quality of the audio. Getting information from the phone on call quality (jitter, etc) may not help because the calls complained about are to an external conference bridge via tol lfree number.</div>
<div> </div>
<div>If this config checks out, I plan to ask the network team if they can capture some data for this particular link.</div>
