Re: H323 Slow Start config....?????

Did you apply the voice class to the peer? The voice service command should apply slow start globally so you won't see any change to the peer if you do it that way.

Configuring Slow Connect for VoIP Globally

To make an H.323 gateway backward-compatible with a destination gateway, use the following commands beginning in global configuration mode. This procedure is optional and selects Slow Connect globally for all VoIP services.

Command

Purpose

Step 1

Router(config)# voice service voip

Enters voice-service configuration mode for VoIP services.

Step 2

Router(conf-voi-serv)# h323 call start slow

Forces the H.323 gateway to use Slow Connect procedures.

Note To restore the default of Fast Connect, use the h323 call start fast command.

Note The previous procedure selects Slow Connect globally for all VoIP calls. To change the type of connect procedures for calls associated with a specific dial peer, use the following procedure:

Configuring Slow Connect for a Specific Dial Peer

Note This procedure is optional and selects Slow Connect for a specific VoIP dial peer.

To make an H.323 gateway backward-compatible with a destination gateway, use the following commands beginning in global configuration mode:

Command

Purpose

Step 1

Router(config)# voice class h323 tag

Enters voice-class configuration mode and creates a voice class for H.323 attributes.

Step 2

Router(config-class)# call start slow

or

Router(config-class)# call start system

Forces the H.323 gateway to use Slow Connect procedures. The default is slow. The keyword system causes the H.323 gateway to use the connect procedure that is configured in the voice-service configuration (see Configuring Slow Connect for VoIP Globally).

Note If you require Fast Connect for a specific dial peer, use the call start fast command to restore the default when configuring the Slow Connect for VoIP globally.

Step 3

Router(config-class)# exit

Exits voice-class configuration mode and returns to global configuration mode.

Step 4

Router(config)# dial-peer voice number voip

Enters dial-peer configuration mode for the VoIP dial peer.

Step 5

Router(config-dial-peer)# voice-class h323 tag

Assigns the voice class attributes to the dial peer, including the H.323 connect procedure that was selected in Step 2.
