I have a PIX 501 at home, VPN'd to the 506 at the office. My 7940 at home, comes up, and I can access data services, but I cannot place calls. The SCCP stream shouldn't be PAT'd, because data to the other network matches a nat 0 access list on both sides of the VPN. What else might be wrong, or won't this work until the 6.2 Code for PIX is release. I kind of thought it's fixes were for voip streams that actually passed through via PAT or NAT, which mine shouldn't...
My understanding is you only disable the skinny fixup protocol if you are not doing NAT. If you are doing nat then you need the skinny fixup. So if you are not doing nat then disable the skinny fixup. What version of code are you running on the pix 501?
I did start a debug skinny and for some reason the pix was trying to do a fixup even with nat 0 traffic. Am I wrong to think if we use the nat 0, it should not try to do a fixup for that nat 0 traffic? I am running a beta code in a lab. I should try it out with 6.1(1)105.
The skinny fixup is only used when you are doing NAT. The Source address and Destination address is in the payload that is why you need the skinny fixup when NAT is enabled. Check out the command reference below.
The document you reference indicates that TFTP is not supported via NAT at this time. i.e. if the call manager is NAT'd and the remote IP phone uses NAT to contact CM for tftp info, then it will not work. Seems like this wasn't the case prior to CM3.1.
I am trying to resolve an issue with a remote IP phone using a valid internet address and accessing the CM via a NAT'd address. I end up with one way audio. I've tried fixup both on and off, no change. I wasn't having this issue prior to CM3.1. I have been told the skinny protocol changed slightly in CM3.1 causing the issue. I have yet to find the fix. Any suggestions?
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
