    Hi All,

    We have a 3CX system setup using Mikrotik RB450 and everything is working for normal calls except for Media-5 SIP Client calls and Skype calls. Previously, we had a Linksys BEFSX41 router in place and did not have issues. The SIP clients are on Android phone devices and it connects to the system fine, but when calls are made or received, there is no audio on both ends. The SIP Client uses the normal UDP 5060 port and the UDP 5070 port which I have added to the NAT config.

    For Skype, making a skype call has issues both ways for specific phones. We are using Polycom soundpoint 550 phones with same firmware versions, but 3 phones work with no issue while 3 others do not have audio both ways, reset the phones, but issue still remains.

    Any help would be greatly appreciated as I need some pointers, thanks.

    Thank you,
