One-Way Audio

Let me explain the config. I currently have an AS5300 gateway sitting on a private network. The AS5300 is fronted with two 3600s in an HSRP config on the private side. I am also running static nat on the public interfaces on the 3600 routers. The public interfaces on the 3600s also are running HSRP. I have an inbound access list on the public interfaces of both 3600s allowing the return traffic from the destination gateway terminating the calls. The access list is configured to allow full ip return traffic back to the originating gateway. Here is the weird part. One way audio on h323 calls every time but, sip works great. I would like to get h323 working. Any help would be greatly appreciated. Thanks in advance.

Re: One-Way Audio

Might seem like an obvious answer but seems like a routing issue. Quick question, why would you want to use H323 instead of SIP?

I am looking to a SIP solution, can this be done with only a 3600 and CCM?
