Hi friend,
The MA5620 supports H.248 by default. To change the H.248 protocol to SIP, run the protocol support sip command.
huawei(config)#protocol support
{ protocolvalue<E><h248,sip> }:sip
Command:
protocol support sip
Changing of the protocol configuration takes effect after you save the data
and then reboot the system. To ensure that the digitmap file is consistent with
the protocol configuation, reboot the system and then re-load the digitmap file.
Are you sure to change the protocol configuration? (y/n)[n]:y
Thanks
