| MCS5100 don't support PRI, only SIP. What kind of SIP/PRI gateway do you use?
If I correctly understand your case you have the following chain:
"2500 analog set" - H323 - PRI - SIP - "MCS Meet-me conference"
What kind of codec do you use on H323 part of way and on MCS ?
PS What do you mean "NEC is h245"? H245 is a media control protocol not a signaling one. |
