Disconnected and re-connected in a few secs only. Still, you're dced for a while.

Non-resumable direct link will need to start again from beginning. 24h cctv surveillance might have some interruptions. Online gaming might dc as well. If you do not mind or you monitor the time ip renewal time, there might as well has no problem.

We found out after testing, theres a problem with one of program online running, since we have unifi too, we tested both unifi and p1 fiber, only p1 fiber got the problem. Management decided its not worthwhile, so even thought p1 fiber is cheaper on same package speed, but the problem lies on p1 ip range. So decided to cancel it.
But nobody knows know to do cancellation on p1 since its not mention on p1 website and what is the penalty since the installation was done this week, tuesday.

So how do we go about the cancellation process, I remember there's trial period for p1 wimax but I dont know p1 fiber got this trial or not. Thanks.

As for the application, its company confidential.

Default 5060 port for sip is often configurable and it can be of any higher ports, UDP.
Why would you use the same port as P1?
Alternately, just release P1's sip port from the voip config.

If you have static IP addresses, you can use one-to-one NAT.
Change the default sip port 5060 on each phone to a different number diff RTP ports.

Now I know why P1 has the weird term:
P1 voice line must be active with bare minimum of one (1) call per month/bill cycle - to any number, on any call duration.
Naturally P1 does not want anyone to mess with or configure their own sip server.

Now this makes me wonder whether
Unifi and Maxis uses 5060 for their sip server.

My suggestion, cancel P1
