The distributed model does not have these two technologies

1-aar

AAR occurs first in the case of an IP link congestion, while the Srst is in the case of an IP link outage

Regional: Put in different device pool, use different encoding

Location: Configure bandwidth to let cm know the current link state

Location test:

1-Create a new ' remote ' location

I use the--->2000 to establish a call, and then use 1001------->2001 will not pass, prompting the wrong

2-reginal Test

Because it is two different site, we recommend that 1000 2000 use 729 encoding when calling, reducing bandwidth usage

Because different region is to hang different device pool, create a new device pool to take out a newly created region.

650) this.width=650; "title=" clip_image008 "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;margin:0px;border-left:0px;padding-right:0px; "border=" 0 "alt = "clip_image008" src= "http://s3.51cto.com/wyfs02/M02/84/56/wKioL1eNx2rh0jY7AAEdg0r3Cho724.jpg" height= "484"/>

650) this.width=650; "title=" clip_image010 "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;margin:0px;border-left:0px;padding-right:0px; "border=" 0 "alt = "clip_image010" src= "http://s3.51cto.com/wyfs02/M00/84/56/wKiom1eNx2_zLzQ-AAB6TT_G-dI082.jpg" height= "187"/>

So, the call on both sides is 729 encoded.

Because the AAR is IP congestion only appears, and to cooperate with the MGCP, the experiment temporarily does not do

2-srst

SRST is triggered when the IP is interrupted or not found, mostly with MGCP rollback

1-Downgrade with device pool Srst

SRST also has a SRST in CME this mode, which requires iOS version 7 support.

The other is through meet me, which consumes a DN, which is the meeting host to build a virtual conference room for Meet Me

First set up a meet me number, say 1007.
