question about h323 fixup and Envision SL software

Has anyone had any experience using Envision SL software (video relay for the hearing impaired) behind a PIX? I am at 6.3.1. The software's gateway server appears to be initiating a control channel on ports 15328-15338. The h323 fixup is not allowing this back in and PIX blocks it. I am assuming it is not RFC compliant. The 1720 traffic seems to be working OK. Is there a way to tweak the h323 fixup to include these ports also? Any other suggestions? Thanks.

Hello Darrell,

Firstly, No I've not come across Envision SL software, but will try to help you out on this - Please if you can provide your PIX config (no real IPs and passwords) also have a read of the following document and see if this helps and let me know,
