Hi, We have a number of DT700 phones connected via a microwave lease line to a SV8100. Whilst you're talking, the phones frequently just disconnect after 10mins or so.

Any ideas on what I could change to make it more tolerant on temporary network link loss. If I do a continuous ping, it looses 1 packet every couple of minutes... Is this causing it?

Thanks.

I have no NEC across microwave yet but our Cisco CM run fine on our corporate campus via microwave linking about 30 buildings across several lakes and roads . Make sure that QOS is being implemented from end to end . If that is not your cup of tea, you would need the IT staff to fully support you on this project as it would need lots of tweak if your network gear is not coming from the same vendor .

You might also try 84-15-03 snd 84-15-04 and bump up the H323/SIP alive timing to see if the DT700 can hang on to the SV8100 heartbeat a bit longer .

Is it 2 systems NetLinked - if so, that tends to be sensitive to interruptions.

If the phones are solo, see if there is a session timeout in the router.

No, its just a DT700 phone straight over IP to the PBX.

I changed the codec to 711 and increased the alive timer per above. Seems to have worked. Also implementing QOS at both ends now to ensure the link is not lost...

Will also check the router settings for session timeout...

I'm having a similar problem -- two remote users working from home, one with cable internet, the other with u-verse. Both phones disconnect somewhat regularly then have to reconnect which almost looks like a boot process and can take a couple minutes. I'm new to this system (only the local computer tech not a phone specialist) and the vendor doesn't seem to know what to do either.

I'd like to adjust the timing as described above but I'm not sure if I'm to adjust up, down, or even what the numbers represent. Is it seconds? 84-15-03 is set to 5 (range is 1-10) and 84-15-04 is set to 3 (range is 1-5).

Just trying to understand.
