Cisco VPN :: 5505 Intermittent One-way Audio Over NEM VPN

Cisco Firewall :: ASA 5505 / One Way Audio For Phones Using IP Proxy?

Jun 5, 2011

I've got an ASA 5505 running 8.2 configured for solely as an IP phone proxy, it is the default gateway for the cucm box and PRI router, its inside interface is directly attached to the same subnet as all internal phones as well. Calls can be placed from either end, but after call is established, proxy phones does not hear audio from internal or pstn phones. The proxy phone registers with cucm with the remote internal IP of the phone that obviously cannot be reached by corp network.

Debugging from pri router shows the rtp traffic destination is the internal ip address of the proxy phone 192.168.0.50, why is the phone registering with its internal IP 192.168.0.50 rather than its Natted external IP 50.50.50.50 that can be reachable by cucm and other phones?Proxy phone is a 7945, after it registers, I do not see it under sh phone-proxy secure-phones, or sh phone-proxy signaling-sessions while on a call.

Cisco Firewall :: ASA 5505 Intermittent Denies From Internal Workstations

Mar 24, 2013

I'm completely illiterate with Cisco appliances but I'm taking care of an ASA 5505 that is configured as a firewall and it has been working for the last years. All of the sudden we are experiencing intermittent connection problems from the workstations. You can be browsing the internet and suddently you'll get a server not found error but you refresh it and it works. This is also intermittent, out no apparent reason it will start working normally again.

I am seeing a bunch of errors like this in the logs:

4 Mar 25 2013 14:34:49 106023 66.235.119.5 69.70.15.61 Deny icmp src outside:66.235.119.5 dst inside:69.70.15.61 (type 8, code 0) by access-group "inbound" [0x0, 0x0]

System image file is "boot flash:cat4500-entservices-mz.150-2.SG.bin"

Cisco WS-C4507R+E (MPC8245) processor (revision 7) with 524288K bytes of memory.
MPC8245 CPU at 333Mhz, Supervisor IV

It seems to be an easy task for routers:

But not for these 4500's
