[c-nsp] 1721 IOS 12.3(14)T2 - SIP/RTP one-way audio

[Anthony Cennami]

I can't believe that I'm emailing this list for something so stupid......

I have a 1721 doing PAT for some VoIP (SNOM) phones connected to an Asterisk
(1.2.10) box.  Customer experiences intermittent one-way audio on calls.
Blah blah -- it's nat.  Yay for me.

Does anybody have this router in a similar configuration, and have a working
solution?  12.4 has a nat option to open the SIP/RTP ports up, rather than
reject them and assign invalid ports, like this version is doing, but I'd
prefer a running configuration option.

There's sure to be SOME solution available, that I'm just not up to date on,
rather than throwing a $50 Linksys that's known working with its particular
firmware/configuration.

Normally I would include all the relevant debugs and what not, but this
problem is so stupid and trivial I'm hoping someone simply knows what I'm
talking about and has dealt with it before.

Thanks,

anthony
