We are experiencing VOIP connection issues which are not related to our limited internal environment. It would seem that the CG3000DCR router/gateway is culprit. Other folks in your forums were experiencing the same problems, which were resolved with replacment of the CG3000DCR gateway with the SMC variant.
How the heck do we opne a trouble ticket to get the replacement in the first instead of posting forum notes. This is kind of ridiculous for business class customers.
You'd need to call Comcast and let them know your issue. May not need to go to a trouble ticket, the standard tech should be able to ship you a new one. I'm not sure if there is a fee involved, though.
actually, if he's having the same issue as the folks in that thread he linked to, then new equipment won't be the solution. According to Comcast_Jon in that thread, neither of the 2 currently rented BCI gateways support disabling of SIP ALG functionality, and it's only anecdotally that some people have gotten this to work with the SMC. The only definite solution would be to buy a standalone modem (and thereby give up static IP(s), which may not be possible/feasible.) Though apparently 1 poster was able to get a CSR to disable it in the Netgear?? idk bout that
But letting Comcast know about it wouldn't be a bad idea; kinda surprised these gateways don't support this
Hello sbaxevanis and welcome,
It is well known that the following is true for VOIP intranetworking:
you must have open some necessary Ip ports
