Hi all,
I writing this post because I'm doing an IPICS 2.01instalation right now. I put 4 channels, one with a nextel and 3 with motorola radio bases.
I have great comunication between the PMC and IP phones to all the channels, but when I enable a VTG on all the 3 motorolas I get a delay in the comunication, like 3 seconds. I'm not sure why this is happening, do anyone know how can I reduse this delay? do I need to change anything in the config?
I have attached my RMS configuration. I thank you all in advance for all your time and help.

Hi,
I'm also having the same problem with my radios. I have 2 brands of radios, a Motorola and a Kenwood. If I use the Motorola, It would take like 1.5 seconds for the LED light of the Kenwood E&M port to light up. It means I have to wait for 1.5 secs before my voice can be heard on the other side. And if I use the Kenwood, I need to speak loud and in a continuous manner before it can be heard on the other side. I have the same config on both voice ports. If I exchange the connection, it's still the same.
voice-port 0/0/0
voice-class permanent 1
auto-cut-through
operation 4-wire
type 3
signal lmr
lmr e-lead voice
lmr duplex half
lmr led-on

I've also tried on changing the parameters. But it seems the same.
Thanks in advance.

Try this config for a Motorola XLT Radio.
The XTS are portables, all models 2500, 3000, 5000 etc. should all behave the same.
The XTL is the mobile.
Motorola XTL series portables. It should also work with XTS series. Are you also using a REM3601 & REM4475 cables from http://www.networkedradio.com ?
You will have to adjust input gain & output attenuation for best audio once its working.

Below is another example.
The XTS5000 operates in VOX/VAD mode as it does not have a COR lead. Most of the time there is no need to do programming to the handset. Simply attached the XTS5000 cable from www.networkedradio.com (REM3601 + REM4475) to the radio, use an in-line 20dB attenuator (REM-621), and then attach to the router’s E&M port.
This configuration was used for both conventional and trunked systems. It seemed to work well as a middle of the road configuration. The areas of the configuration you will need to consider for these various types of systems will generally be timing delay-voice tdm and timing hangover.
You will also want to be careful to consider if these resource will need to be cross-patched with other resources. The configuration I sent was designed for this capability in mind. However, this configuration prevents status tones such as binks and bonks from being heard from the IPICS user as the ports are set to half-duplex. A longer discussion will ensue if you need status tones to be heard.

Hi John,
I'm using Motorola GP328 and Kenwood TK2107. I tried the your first example on the Motorola. If I speak on the Motorola, it takes about 1.5 to 2 secs before my voice is heard on the Kenwood radio.

Try decreasing the delay timing delay-voice tdm 250 to a lower value on the radio voice ports. Make sure you do a shut no shut on the port after making the change.

Hi John,
I've already removed the timing delay-voice tdm command. By default, the delay is 0ms right? How about your setup, aren't you experiencing delays?
Regards
