Dialing method between H.323 and SIP Participants
The RMX system can work as a gateway to enable the H.323 or SIP
participants inviting the SIP or H.323 participants when creating a
conference.
If the GK and SIP server are not configured on the network, dialing is
executed in the same way as for inviting the same IP type endpoint. For
dialing strings please refer to the previous section.
If the RMX 1000 and the endpoint are registered with the GK or SIP server,
the format of the dial-in string is as follows:
Dialing Direction Dial-in String
H.323->SIP
<RMX 1000 E.164 prefix>[Conference ID][##Conference
password][##Chairperson password]<* SIP participant's
TEL URI>
Here, the character in the <> symbol is mandatory, and that in
[ ] is optional.
Note:
For an H.323 conference creator to invite a SIP
participant, if the H.323 endpoint has been registered to the
same gatekeeper as RMX 1000, the SIP endpoint needs to
register the SIP server with a numeric URI and the RMX 1000
should also register the same SIP server.
SIP->H.323
[Conference ID][$$Conference password][$$Chairperson
password]<* H.323 participant's E.164 prefix>@<RMX 1000
static route domain name>
Here, the character in the <> symbol is mandatory, and that in
[ ] is optional.
Note:
For an SIP conference creator to invite an H.323
participant, if the SIP endpoint has been registered to the same
SIP server as RMX 1000, both the H.323 endpoint and the
RMX 1000 need to register the same gatekeeper.
In the gateway scenario, the user can create a conference between an H.323
participant and a SIP participant as a point-to-point call through the
procedures below:
1 Select the Terminate the call when last participant remains option in
the default profile and keep the default idle time value (0). For more
information about conference profile, please see Defining a Conference
Profile.
2 Dial [RMX Prefix]*[another participant’s E.164 or SIP URI]
In that way, when one participant disconnects, the other participant will be
disconnected automatically like in a phone call.
• Conference ID is not mandatory. If the user only dial the RMX 1000 E.164/IP plus
*participant’s E.164/SIP URI/IP, a conference will be created with a random NID.
• The conference ID the user enters for creating a new conference must be unique -
different from existing conference IDs.
• If only one password is entered, it will be defined as a chairperson password. In
this case, there won’t be a conference password and the user will receive the
chairperson privilege.
• The conference password and chairperson password must be different. If a user
enters the same password for both, the call will be rejected.
