Troubleshooting

Required software for CS1000E call server in MCS5100 conﬁguration

If your MCS 5100 resides on the same network as a CS1000E, make sure your CS1000E has the following patches installed:

•MPLR22491

•MPLR22494

Known issues

•Successful NAT/Firewall traversal requires an RTP Media Portal (same as MMPC client).

•If the IP Phone 1535 is installed within an IP Telephony environment in which the G.723.1 codec is not supported by all endpoint devices (on the same node), the IP Phone 1535 G.723.1 codec must be set as the lowest priority (default setting) to avoid codec negotiation related issues.

•Selecting the Korean language for your menu language option causes the IP Phone 1535 to reboot automatically to enable the changes.

Basic troubleshooting

Check physical connections on the IP Phone 1535:

•For power related failures ensure that the power supply is connected, as IP Phone 1535 does not support PoE.

•For issues of connectivity loss, check all installed cabling for the IP Phone 1535: are all cables installed ﬁrmly and in the correct ports?

•If the handset has no audio, check to see if the handset accidentally connected to PSTN RJ-11 connector?
