firewall recommendation for ip office sip trunks

[redswine]

I am quoting a new IPO with SIP trunks. They are a medical facility and don't want the IPO on their network, so I need my own firewall between the IPO and Comcast modem. I am pretty network savvy and don't suspect setting it up would be that difficult. But pricing is the bigger issue, would prefer something without a yearly subscription.

Thanks in advance.

We've used Ubiquiti EdgeRouterX SFP and all of the SonicWall line with success. Guess it all depends on what you are comfortable with, and what other services you might need down the road (such as remote extensions in addition to the SIP trunk)
