Am using rb532 indoor board with v2.9.42 OS working fine except Sip to Sip calls are not working on Linksys PAP2 v1 firmware 3.1.22. When i call PAPB from PAPA, i cant hear the PAPB but PAPB can hear me but faintly.
I've enable NAT mapping & NAT support on the Linksys and now i can make SIP 2 SIP calls fine but the sound quality is terrible. I suspect the NAT Firewall on the RouterOS is affecting this. How can i disable the firewall or better still enable this ports on routerOS? Is the beta v3 OS better in handling SIP calls?
SIP signalling ports (UDP) = 5060 - 5061
DNS port (UDP) = 53
TFTP port (UDP) = 69
RTP/RTCP ports (UDP) = 10000 - 30000
Thanx in advance
