Verizon was troubleshooting a problem and included this information about our cube gateway. They have been in use for more than 4 years so I am hesitant to make any changes to our cubes based on their information and I have no idea where I would make a change to implement their recommendation below. Anyone have any idea where this change would be made...if even in the cube??
If anything on this 2nd call, we see that your gateway is using delayed SDP in its REINVITEs (sending the SDP in the ACK) and that it also used a SENDONLY attribute a couple of times when placing the caller on hold. While delayed SDP is allowed, it is not supposed used when placing callers on hold. Please see if this can be changed at your Hub2 gateway (IP address x.x.x.x).
Thanks

if you are using CUCM, you can check the option 'Require SDP Inactive Exchange for Mid-Call Media Change'
