I'm remotely helping a new client with just a few phones. Phones are not registering. I'm waiting on the model# of the Comcast modem so I can look into the configuration, SIP ALG etc. They don't have anyone technical onsite. With the information they've given, I'm trying to understand the network. May need to call someone in, but maybe you guys have some experience with the Comcast/Edgmarc/Polycom network design and can help me understand how it is working so I can deploy 3CX phones alongside.
From the info I've been given:
All endpoint ethernet drops go into an unmanaged Netgear switch.
Out of the Netgear, there is connection to Comcast Business/Cisco modem/router, which I assume does dhcp etc for the PC's.
Also out of the Netgear, there is connection to Edgemarc router, which then goes to an Arris modem.
So the local lan appears to be shared between PC's and the Comcast Polycom phones, but somehow through the same unmanaged switch, the phone traffic goes out the Edgemarc then Arris and the PC traffic goes out the Comcast Business modem.
Is this as simple as the devices are all on the same subnet, Comcast is the DHCP server, but the Polycom phones are provisioned statically with the Edgemarc IP as their gateway?
