Have a client using Talkdesk, which is a VoIP-type product that uses both a desktop app and a browser-based (Web-RTC) app for calls.
We keep seeing dropped calls. We have brought in fios to augment cable service, verified that we have enough bandwidth, set “voip protocols” to high priority in the QoS section yet still have issues.
Talkdesk wants more changes, none of which seem to be available on the Peplink:
- Setup destination-based QoS rules to prioritize voice (Peplink only supports source IPs) to Talkdesk’s servers
- Setup DSCP rules to try to catch/prioritize the softphone traffic
- Turn off all SIP “helpers” (ALG) - this does not appear to be an option (why not??!??)
- Check and possibly increase NAT UDP timeout for sessions (I think this is actually the problem - peplink doesn’t see this non-standard VoIP as VoIP and aggressively terminates NAT sessions)
The last two really bug me, am I just not seeing those options or are they really not adjustable?
