My topology is a typical centralized call manager/unity connection deployment. like below
Remote Site1, IP phones and gateways at remotesite1 device pool, within the region, G.711, with other regions, G.729
HQ, IP phones, gateways and voicemail ports are in HQ device pool, within the HQ region, G.711, with other regions, G.729
on the Unity Connection, I setup call handler for RemoteSite1 AutoAttendant, so when remote site1 local PSTN caller called the AA pilot, Unity Connection will answer the call
because the region setup, so all remote site1 outside caller called the AA number, hit the gateway, show voice call summary, shown only G.729 call (which is right, but voice quality is not that perfect). is there anyway I change such G.729 call to G.711 call without change the region setup? I really means the xcode method.
(btw, my current unity connection accept both G.711 and G.729 codec while recording format is G.711, I plan to remove the G.729)
I added the hardware transcode resource to the remote site1 device pool.
my question is, if the xcode resource will be added on the call at the time hit the gateway or xcode will be inserted at the HQ site? if not at the HQ site, is all the call go WAN will become g.711?
overall question is, based the setup, what the best practice is to ensure better quality for AA over the WAN?
for my case, if Unity Connection only support G711 codec, so the outside caller at Remote Site1 called the AA, the call across the WAN is still G.729, however, after hit the Unity Connection, xcode resource will be inserted by CUCM, therefore, the call became G.711 between CUCM (???) and the vm port?
you mentioned for this case, the xcode resource will be invoked from remote site router, right? my understanding is the xcode resource close to the destination, so would be xcode in HQ or soft xcode
if the Unity Connection support g.729, so the end2end call will be g.729, however, since the recording format is G.711, so when the caller hear the greeting, it is somehow a G.711 call, please clarify, if it is, another xcode resource needed, who will be the resource? HQ or RemoteSite1?
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
