Hello,
Was hoping for some guidance on setting up an ESI 100 with a SIP8 Card using Spectrum SIP. Have been trying to get this working for a month and keep having to move the cut date. All the settings in the System have been verified by ESI Tech Support to be correct, debug and packet capture are showing incoming and outbound audio on calls, however the outbound audio ( transmit ) does not make it to the called party. We have tried this with the router firewall disabled, same result. Set up a different cabinet with a different SIP8 card, same result.
Calls go out, connect to called party, I can hear them but they cannot hear me.
Have tried hooking the SIP8 and Spectrum eSBC together outside the network, connected to a mini switch ( SIP Primary, SIP Secondary, and eSBC Lan ) same issue, no tranmit audio at called party.
Any one done a Spectrum/Charter/Time Warner SIP install, they ( Spectrum ) are being of absolutely no help. They have a document on how to set the system and we have followed it to the letter, there is a link to it below. Any Ideas?
