I have installed 2 RV220w routers and 5 RV120w routers on a 7 site vpn ( all with the latest 10.5.8 furnware)
I am running an Elastix 2.4 asterisk based pbx
The issue I am having is this:
With the sip alg disabled and the port forward set for 5060 udp and 10000-20000 udp I cannont recieve sip calls
With the sip alg enabled and the port forward set for 5060 udd and 10000-20000 upd I can reiceive calls BUT
the rtp packets are coming at any random port 9000 to 50000
Aparently the sip alg is rewriting the sip header causing this
Normally I would run this with the sip alg turned off but in that mode I cannot get the sip port to pass calls at all
I am thinking of downgrading the firmware to the 10.4.17
Does anyone have experience with this
Thanks
