one-way audio

Hi, I have a:

ATA 186 with Version: v2.14 ata186 (Build 020521a)

IPPhone 7905 with Version: v1.0.h323 ld(020603b)

Cisco C2610 with Version 12.2(11)T8

When I make a call from ATA 186 or IPP 7905 I experience a one-way audio only. If I run a show call active voice brief command on cisco gw I see that rx packet are equal to 0.

2F10 : 24574558hs.1 +295 pid:1 Answer 78255155773 active

Tele 1/0/1 (148): tx:8740/874/0ms g729r8 noise:0 acom:2 i/0:-40/-82 dBm

I don`t have a problem with networking or NAT, the three cisco devices are in the same LAN. If I use the IOS 12.2(8)T5 I don't have any problems.

The question is:

Is there a bug in ths Cisco IOS 12.2(11)T8 or do I need to make a new consideration in the configuration?

Thanks,

Re: one-way audio

I all ready have this commands in the configuration and the labs is in the same LAN, the rarely is if I use de IOS 12.2T5 it’s works fine, the problem is with the IOS 12.2(11)T8. My doubt is if it's a bug or I need to take a new consideration whit this IOS. I search in the cisco web but I don’t see nothing about this.
