This thread is to hopefully help me understand if I can run both fax passthrough and fax relay on the same MGCP gateways, including 6608s.<br><br>We have a site (Site B) coming on board that is currently using cisco fax relay on their gateway and on most of their VG248 ports (some VG248 ports have relay disabled). They have a 3725 running a PRI (MGCP).<br><br>HQ (Site A) has a bank of 6608s (MGCP) and a couple of PRIs on a 3845 on a remote gateway (also MGCP). We have VG224 ports used for modems/faxes at the remote site. Everything is configured for fax passthrough and is working hunky dory.<br><br>Is it possible to configure the HQ gateways (both 6608s and 3845 ports) to recognize both passthrough and relay? Are there problems doing this?<br><br>I've included some relevant config info below.<br><br><div style="margin-left: 40px;"><hr style="width: 100%; height: 2px;">CallManager 4.1(3) -> upgrading to
