Sangoma SBC with Cisco 4331

[AdamG73545]

Hello,

Wonder if their SBC would work with Cisco 4331 voice gateway for SIP trunk. Any recommendations? 

[Nithin Eluvathingal]

why don't you use CUBE on Cisco 4331 to terminate SIP trunk ?

[AdamG73545]

I use CUBE on it. I just wonder if extra security layer would be helpful is worth that pain.

are you looking SBC sip trunk with Cisco 4331, do you have any Cube running or any other SIP Server running on 4331 ?

[AdamG73545]

yes - I have already had SIP trunk configured on 4331 with CUBE, like I mentioned before wonder if extra SBC would be helpful or just 4331 CUBE is enough.

depends on requirement, if you looking more resilinet required along sip (if one fails)
