router rt-ac88u phone ip

[chiquito]

I have a router rt-ac88u to which I have put the latest firmware to this router I have connected a gigaset c530ip ip phone with movistar spain, it turns out that I do not register the phone always tells me registration in prov failed, you know why it can be?
I've tried it with another router rt-ac87u with merlin firmware and no problems ..

If present, try this router setting:

WAN\NAT Passthrough\SIP Passthrough: Disabled

Is the other router rt-ac87u with you there on the same Internet connection such that you can go back and forth, works on the 87U now but not on the 88U?

You may want to try switching off airtime fairness for the router on all bands, it resides under the professional tab, this may help with the printer problem.
