<div dir="ltr"><div>Hello All, <br>I am working on a new CUCM 9.1 deployment with several branch offices using PRI's. <br><br></div><div>Reading through the SRND and a few messages on this board, I am still not sure which protocol to use for these gateways. <br>
<br></div><div>I know SIP is really prevalent now, and is much easier to troubleshoot, but not sure if there are any issues in terms of features. <br></div><div><br></div><div>Additionally, this deployment will involve several VG 224's for fax, and analog IVR components. <br>
<br></div><div>Does anyone have any suggestions either way SIP, H323, or MGCP or particular features that work better/worse using a particular protocol?<br><br></div><div>Thanks!<br></div><div><br></div></div>
