C7100 V | Voice Choppines, Quality issues

 

Used this device to switch over my phone service to Comcast from Vonage.  I have always had Comcast cable internet (Blast+) and never had any quality issues with Vonage.  Ever since the switch over, the call quality is unusable.  The remote end can hear me just fine, but their voice is choppy and I only make out every other syllable at best.  

 

We've done the old "restart everything" routine, and even had a tech come out and replace connectors, which seems to have cleared up the issue long enough for him to get into his van and drive away.

 

I have no issues with the internet.  Speeds are fast, no issues with streaming or gaming.  

 

I have disabled SIP ALG but to no avail.

 

C7100V

Firmware 2.01.30

 

 

I am going to call for Comcast to come out and look again, however I am not sure that will do any good and I am wondering if it is the device itself.

 

Anyone ever had this issue with the C7100V and how can it be resolved.

 

 

  • The firmware was released by comcast today you may want to do a reboot on the modem by unplugging the power and powering back on so the modem will download the new firmware.

  • I'm also facing similar issues and I was hoping that I can use QOS and prioritize my Vonage device.. but they don't have this feature enabled on this router.

      Just to clarify,  my issue isn't with Vonage, but with Comcast Voice.  Vonage did not experience this issue on my old modem.  Trying to find a solution fo rthe built in voice function of the C7100V.
