SIP Gateway for Cisco UC520
We are installing a Cisco UC520 system at a site that has had analog phone lines till now.
As per my understanding, a SIP Gateway would be the best way and more cost effect way compared to analogue Verizon lines.
I am looking for some really good quality SIP Gateway providers that are reliable as well.
I don't think the big telecoms(verizon and ATT) offer such SiP gateway services.
I have heard bad stories such as poor voice quality and service outage for some of the relay cheap ones.
Also, we would be using a Comcast cable modem line (25MB down/ 12 MB UP) at this site which is also shared with the computers.

BTW your UC520 supports SIP. You do not need another SIP gateway. You just need to configure a SIP trunk on your UC520 that points to your carrier.

So, in that case , should I be searching for SIP trunk providers? How are some of the best ones out there.?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You need a dedicated 1/1 contention business grade symmetrical data line for connecting to your voip carrier, such as SDSL/SHDSL or leased line that support QoS. Your round trip delay to your carrier should be below 100ms. You need to implement QoS on your network.
It is best, if you get a managed voip service where your carrier will provide and manage your WAN connection and gateway. They will make sure it works.
You can still use your cable modem for internet connection.
