Managing multimedia calling

277Enhanced Mode MM complex

Call association (routing). Typically incoming voice calls consist of 2 B-chann el

calls to the same address, to provide greater bandwidth and better video

resolution. DEFINITY ECS attempts to correctly pair up incoming calls and offer

them as a unit to a single agent. MMCH uses call association to route both calls to

the extension that answered the first call, regardless of how the call was routed

internally.

Two 56K/64K data calls with the same calling party number to the same

destination number are considered to be associated. The system makes every

attempt to route both calls of a 2-channel call to the same answering party. If the

first call terminates at a member of a hunt group, the second call does not have to

hunt, but goes directly to the same member.

In order for 2B multimedia calls to be correctly given to a single agent, incoming

calls to the hunt group must have ANI information. The ANI information may be

in the form of ISDN calling party number or DCS calling party number.

Multimedia calls made on the same switch as the hunt group are easi ly as sociat ed.

If multimedia calls into a hunt group have insufficient ANI information (i.e. all

calls from switch X to switch Y include the LDN for switch X), then as the

volume of calls increases the number of mis-associated calls will increase. If

multimedia calls into a hunt group have no A NI information, the switch will never

associate pairs of calls and all calls will be treated independently and routed to

separate agents. This is not a recommended configuration.

Multimedia vectors. Very often, calls are routed to hunt groups or skills via a

vector. The existing VDNs and vectors which exist for routing voice calls can be

used to route multimedia calls.

In order to use a vector for multimedia calls, you must set the Multimedia f ie ld on

the vector form to y. This field has no effect on voice calls routing through the

vector. This field will cause multimedia calls routed through the vector to receive

early answer treatment prior to processing the vector steps. This provides a talk

path to the caller for announcements or immediate conversation with an agent.

NOTE:

Vectors which have the Multimedia field set must eventually route to

hunt groups, skills or numbers which are voice extensions. A vector

with the multimedia field set to y should never be set up to route to a

hunt group or number which is a data extension.
