Hi Guys,
I'm looking for some help with an issue i appear to have hit a brick wall with.
System setup:
SW: 7.0(36)
Controller: Ip500 V2
Peripherals: VCM64,COMBO621/ATM4, x 2 Phone 30 V2's,x1 DS8
Handsets: 60 ATL berkshire analogue handsets x14 digital handsets x1 56 series IP handset (remote VPN )
Voicemail Pro
Phone manager PRO
Symptoms:
Customer reporting on inbound calls echo is persistent on analogue handsets (becomes progressivley worse as the call duration increases no chopped or missing audio purely echo)
Diagnostics:
Upgraded from 7.0(23) - 7.0(36)
Customer replaced old analogues with brand new Berkshire ATL handsets
test calls placed in from mobile/Landline to the main number have identified if the call is collected by a user on a digital phone there is no echo if the same call is transferred to an analogue set the echo appears, if transferred to another digital then again no echo.
Adjusted the echo los settings and can minimise but not able to remove the echo.
Confirmed Echo occuring on devices located on both phone modules (Also re patched two of the devices directly onto the POT ports on the COMBO and the echo persists)
Phone plugged directly into pot port of the combo and again echo persists (ruling out internal cabling i would presume)
Spoke with gamma ethernet team they have checked the router and cannot see any erroring on the interfaces, SIP tracing and call captures from the Carrier show no Echo on the external part of the call.
Reprogrammed IPO SIP trunks/IP routes from Scratch
Replaced VCM64
replaced all cabling from the IPO to the Carrier NTE.
No packet loss showing on SSA
Seems to point to analogue handsets just not wanting to play nicely on IP calls however Issue has only become prevalent since the Set up was swapped to SIP.
Looked into the possibility of upgrading the site to release 9 however the end user would loose phone manager and frankly is unwilling to pay the additional costs to have Onex set up
8.0(46) Q3 2012 appears to still run support for PMP however unsure if this would be a worthwhile excercise
Thanks and appreciation in advance
Symptoms.
Inbound call over Gamma SIP (converged) terminating on analogue handsets results in Echo
