cisco 1921 let sip traffic pass through

Hi

We have a brand new cisco 1921 that doesn;t want to let sip traffic pass through

Incoming calls can get in, but if we answer, it hangs up.  
Outgoing calls are fine as well as calls betweenphones on the internal network

I need some help

Sounds like the firewall is blocking the return RTP packets.  Do you have IP inspection turned on?  If so, do you have an inspect rule for SIP?

no, the IP inspection is not turned on

dio you need a sample of the logs?

I would create a rule then

ip inspect name VOIP sip

And apply it inbound on your LAN interface.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Would be nice to a) show part of the config and b) reveal how you "solved" the problem.
