UDP timeout settings for SIP

I have a single sip phone and have set the NAT rules up.
Connections work and outgoing/incoming calls work, however are talking for sometime the call drops.
i see on pfsense forums that they say the default UDP timeout is too aggressive for sip and needs to be increased.
it that true for opnsense as well? if so, where do we do it?

Yes, try Firewall: Settings: Advanced: Firewall Optimization set to "conservative".

found it, thanks.
Issue seemed to be with the vpn - although i didn't have the issue when there were no rules.
I setup the VOIP connection to bypass the vpn and it seems to work now.

Is your OpenVPN UDP or TCP? Or IPsec?

It could be that OpenVPN TCP is more reliable in this case.
