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.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US style='font-size:11.0pt;color:#1F497D'>Hope this helps</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US style='font-size:11.0pt;color:#1F497D'>Ariel.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US style='font-size:11.0pt;color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span lang=EN-US style='font-size:10.0pt'>From:</span></b><span lang=EN-US style='font-size:10.0pt'> <a href="mailto:cisco-voip-bounces@puck.nether.net" target="_blank">cisco-voip-bounces@puck.nether.net</a> [mailto:<a href="mailto:cisco-voip-bounces@puck.nether.net" target="_blank">cisco-voip-bounces@puck.nether.net</a>] <b>On Behalf Of </b>Abebe Amare<br><b>Sent:</b> martes, 25 de octubre de 2011 11:00 a.m.<br><b>To:</b> cisco voip<br><b>Subject:</b> [cisco-voip] Unity connection one-way audio</span><o:p></o:p></p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'>Dears,<br><br>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?<br><br>best regards,<br><br>Abebe Amare<o:p></o:p></p></div></div></div></div><p class=MsoNormal style='margin-bottom:12.0pt'><br>_______________________________________________<br>cisco-voip mailing list<br><a href="mailto:cisco-voip@puck.nether.net">cisco-voip@puck.nether.net</a><br><a href="https://puck.nether.net/mailman/listinfo/cisco-voip" target="_blank">https://puck.nether.net/mailman/listinfo/cisco-voip</a><o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p></div></body></html>
