ASA IPSec Tunnel Dropping VoIP traffic

[bobbarke]

I have an IPSec tunnel running between an ASA5510 and an ASA5520.

Call setup works fine. When the phone goes off hook, only one side of the conversation can be heard. It does not matter what side of the tunnel you are on and it is intermittent behavior.

The phones are not Cisco, the are made by Shoreline Communications (Shortel).

Has anyone ever experienced this issue. Both ASAs are running 7.0(4).

The management-access command lets you define an internal management interface using the IP address of the firewall interface specified in mgmt_if. (The interface names are defined by the nameif command and displayed in quotes, " ", in the output of the show interface command.)

The management-access command is supported for the following through an IPSec VPN tunnel only, and you can define only one management interface globally:

SNMP polls to the mgmt_if

HTTPS requests to the mgmt_if

ASDM access to the mgmt_if

Telnet access to the mgmt_if

SSH access to the mgmt_if

Ping to the mgmt_if

Syslog polls to the mgmt_if

NTP requests the mgmt_if
