Have a remote site whose DID's reside on a router at HQ. This is also where the CUCM cluster resides (HQ). Calls from PSTN to users direct number have a consistent issue where the caller can hear them, but the users cannot hear the caller. If the caller calls into the main number which goes to a call handler and then selects the users extension, when that calls connects, both parties can hear each other.
During a direct call to a user I could see on the Web GUI for the phone that there are no receive packets. I am trying to differentiate why dial by numbers works and direct to the user does not.
Any idea's

Mostly its could be routing issues, can you share more details about you connection type. SIP or PRI ?
What's your gateway type.
Ping from phone subnet to gateway and vice versa and see if you are able to reach each other. if any firewall in between check the firewall configuration too...

Hello and thank you for your reply,
Yes I can ping from phone subnet to the gateway. The gateway is a 4331 ISR router with a PRI connection.

you need to test the ping from gateway to phone subnet too...
