The default maximum channel capacity for a T1 VoIP system is 384
(24 channels per trunk, with a maximum of 16 trunks). The limit only
applies when connecting Blueworx Voice Response to a traditional
telephone network.
When configured to use a VoIP connection with DTNAs, there is no
physical reason for this limit. It is therefore possible to configure Blueworx Voice Response as an
E1 system when in a traditional T1 environment to enable an increase
in capacity to 480 channels (30 channels per trunk, with a maximum
of 16 trunks).
Restrictions:
- This change will only work if the WebSphere Voice Response system
is a VoIP only configuration. If there are any physical adapters,
DTXA or DTTA, the change cannot be made.
- If any state table applications use uncompressed voice segments,
this change will not work as the audio is stored in mu-law for T1,
and so will play in the wrong format for an E1 system.
Configuration process
To configure Blueworx Voice Response in this
way, the Country / Region section of Pack Configuration
needs to be set to Other E1. To do this, complete
the following steps:
- Use the dt_setowner command to
reconfigure the DTNAs as E1 as described in Setting ownership of the DTNAs.
- Start Blueworx Voice Response.
- In the Blueworx Voice Response Welcome
window, click Configuration -> Pack Configuration -> Change.
- Click Country / Region, and choose Other
E1 as the country, press OK and
then OK again to confirm the choice.
- Configure the packs and channels as usual, as described
in Configuring Blueworx Voice Response for Voice
over IP, save the changes, and restart Blueworx Voice Response.
If the Blueworx Voice Response system
has been used as a T1 system previously, and is running VoiceXML applications,
it will also be necessary to delete the VXML2 audio cache before taking
new calls. To do this, perform the following steps:
- Stop VRBE if it is running (dtjstop followed
by dtjshost -exit).
- As dtuser, cd into $CUR_DIR/voice/ext/v2c and
delete all directories and files within that directory.
- Restart VRBE (dtjshost followed by dtjstart).
