What's happening is that, i have a cisco 1801 with about 5 Vlans, im having problems on my voip vlan, like, 2, 3 days ago, 3 of my phones(2Cisco, 1 Grandstream) started having issues, i can make and receive calls, but i cant hear anything, neither can the other party. Strangely, 3 other phones work, they are all linksys, or connected to a linksys voip adapter.

I already know whats causing this, i just dont know how to solve it, maybe some of you have any ideia about this, before i try another IOS version.


Heres some info(if you need more just tell me):


nat table -

udp myexternalip:0 myinternalip:28964 213.13.89.67:41290 213.13.89.67:41290


IOS version - c180x-advipservicesk9-mz.124-6.T6.bin


Cheers

Try reloading the router.

Ok, the things i've done so far:


Cleaned the NAT table, took access-lists off the vlan and dialer interface, also took off the inspect from the dialer interface.


Cheers
