<span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; "><div>Hello all.</div><div> </div><div>I've got a e1 pri line in my office, terminating by cisco 2821. The compand type for E1 (Europe) is A-law, and show voice port 0/0/0:15 also tells me that.</div>
<div>E1 is registered via mgcp, and i also see the compand type A-law in options there.</div><div> </div><div>When i press the question button twice during the pstn call, the negotiated codec is u-law.</div><div> </div><div>
The default codec in Region is "G711" (no option for a-law or u-law)</div><div> </div><div>Is there such an option in CUCM to change the default modulation type for g711 codec?</div><div> </div><div>Thank you.</div>
