I realize this topic is coming up on two years old, but, as of the recent release of firmware revision 8 on the Balance series, it doesn’t appear to have been addressed.
We’ve recently been hitting brick walls with using Asterisk IP solutions (cloud-based) with Balance series devices. This is due to the same inabilities of the appliance to handle some basic configurations.
It appears that Peplink software has a hard-coded default value of 30 seconds per UDP session, 180 seconds on the UDP established/streaming session, and 3600 seconds per SIP 5060 session. The main issue is that the SIP 5060 session needs to be able to have its default value changed to 180 seconds.
This is a significant issue for us as a reseller of Balance (and other Peplink) products as we have more and more clients moving to Asterisk/FreePBX IP voice systems. Just in the last week I’ve had to send a tech to swap out a Balance One Core with a competitor’s unit (one of which was in place for less than a week). I’m not a big player in the Peplink world, but we have roughly 60 units in play at client locations now, and I really don’t like the idea of having to start pulling Balance units out and putting FortiGate units in.
It was recommended to me that I post to this thread to see if we can get software engineering to at least look into addressing this so that I can make an intelligent decision on whether we need to start pulling Balance units (and stop recommending them altogether).
I appreciate your response in advance.
