VOIP Issues

[george.georgiou1]

Please let me know if this is the wrong area for this question...

I setup a Cisco VPN client to our office. Down this tunnel I use the Avaya Phone Manager software to run voice through, which worked just fine for months. The phone system is an IP Office 3.0.56.

But, for no apparent reason, whenever a call comes to the remote user (at home) they just can't answer the call. Pressing the answer button/hitting return does nothing, yet the call is being presented to the user.

If the user makes a call, it all works just fine!

Internally, it works fine, it's just the VPN that it seems to be 'upset' with.

Anyone have any ideas I could try?

The PIX is version: 7.2(1)

The Cisco Client is 5.0.340.

This is late, but I hope you find it.

Turn off fixup h323 for both h224 and RAS on your PIX. That has cleared up TONS of weird issues with Avaya VoIP over VPN.

Thanks for checking this and your reply.

But, I had to remove all voice type fixups when I first set this all up, and it did work just fine.

And now, it's all gone wrong :-(

It works just fine on the LAN, it's only when I connect using the VPL client.

I just don't see where it's gone so wrong.
