RVO42 and Layer Gateway Application SIP-can it be disabled?

We use a phone system requiring a layer gateway Application SIP should be disabled on the router.  We have replaced former RVO42 routers with the WRVS4400N router and VOIP phone works very well with this option unchecked checkmark.

The new router RVO42 allows to disable this option?  I did find it in the manual to date.  I don't want to buy two routers and find that it won't work with the telephone system.  We have Dual WAN this time so I thought that we would try RVO42 model again as long as it is the most recent version.

Someone had problems with the RV042, RVO82 new with VOIP NEC phone systems?

Thanks for any help.

RV042/RV082 does not support SIP ALG, so no conifguration option to disable.
