Hi everyone, I have a quick question that I am unable to find the answer to via google.
I have the following setup
Remote VGW --h323--> CUCM --sip--> CUBE --sip--> PSTN
I have "Early Offer support for voice and video calls (insert MTP if needed)" on the sip profile for the sip trunk to the CUBE, and "inbound fast start" enabled for the H323 VGW. This setup solved an issue with ringback on outbound calls.
My question is when MTP is invoked, which MRGL is used to select the MTP resource? The MRGL on the SIP Trunk or the MRGL on the H323 VGW?
