VOIP issues 376.49_5 / AsusWRT-Merlin / AC-68u

[tloxari]

Hello

I have already issues since a longer time with VOIP. The thing is, after calling 2-3 minutes there is a kind of latency coming into the call which may end up to 5-10seconds. this is then really bothering as you can't go on talking on a normal level.

Anyway, i just upgraded my AC-68U to the latest version 376.49_5 and still have the same issue.

I also disabled the SIP ALG according other forum posts here with the commands:
nvram set nf_sip=0
nvram commit

And in WAN -> Nat Passthrough I've disabled SIP passtrough. All did not help. I'm pretty sure it's the router, because if I take the same laptop to another location with another router I don't have any issues at all.

Anyone any ideas what I still could try?

- Internet-Connection is 80mb up/down fiber
- ping latency is 1-2ms

thanks for any suggestions

Take a VoIP test and wait until all result tabs (should be seven tabs) on the right are shown.

After all tests are done click on summary.

just one question, should i keep SIP ALG disabled or enabled for these tests? because with disabled i get a lot of blocked errors
