1e. TCP/UDP port requrements. To ensure proper functioning of the MultiVOIP, the TCP/UDP network connection must not be blocked on the network connection between the MultiVOIP and CM.

The UDP ports used by the MultiVOIP are as follows:

Channel	RTP Port	RTCP Port	T38 Port
1	5006	5007	5008
2	5016	5017	5018
3	5026	5027	5028
4	5036	5037	5038
5	5046	5047	5048
6	5056	5057	5058
7	5066	5067	5068
8	5076	5077	5078

The TCP ports used by the MultiVOIP are as follows:

H.225 Listen Port – User configured for each channel in the CM Settings screen (default 1721 – 1728)

H.225 Client Port – Dynamic (16000 – 20000)

H.245 Listen Port – Dynamic (16000 – 20000)

RAS Client Port – Dynamic (16000 – 20000)

1f. Emergency Transfer. Emergency transfer allows local analog telephones to access the local CO and to answer telephone calls during a power failure.

For the various products the features operate as follows: MVP210-AV

Port 1 is connected to Port 2 MVP410-AV

Port 1 is connected to Port 2 Port 3 is connected to Port 4

MVP810-AV

Port 1 is connected to Port 2 Port 3 is connected to Port 4

For example, suppose ports 1 and 3 of MVP410-AV are configured as FXS with telephones attached. Ports 2 and 4 are configured as FXO trunks with CO lines attached. If there is a power failure, the telephones on ports 1 and 3 would automatically be connected to the CO lines attached to ports 2 and 4 allowing inbound and/or outbound call to be make.

Note: This feature shall only be available on “AV” models of the gateway that are: Rev B: For the MVP410 and MVP810 models

Rev B: For the MVP210 model
