[cisco-voip] Unity connection one-way audio

[ROZA, Ariel]

Abebe,

 

  It seems that you need to recheck your NAT configurations in the ASA.
It seems that the IP addresses negotiated in the call setup for media
transmissions is not being translated on the ASA (Essentially, the Unity
Connection address) so when the call is negotiated, the 2911 Gateway
received the untranslated UC address, and it will never receive an audio
packet with such an address, hence the silence.

 

Hope this helps

 

Ariel.

Dears,

We have a remote site with a Cisco 2911 ISR G2. Incoming calls to the
main DID are redirected to a Unity connection call handler at the main
office. The main office and the remote office are connected through an
ASA 5510 site-to-site VPN. There was a NAT configuration change done on
the ASA and the problem started after that. Calls between phones in the
two offices are successful and I can ping the Unity Connection server
from the remote office The issue is that incoming call to the main line
hear silence. There is also nothing appearing on the Unity port monitor
tool. Can you point me what to look for to solve this issue?

best regards,

Abebe Amare
