transferred calls not going to vm cover

[jtierney]

This one is complicated.
We have a 5 site school district SCN (406 @ core of a fiber-connected VLAN'd network w/ remote hub/spoke 401, 403's, and 412).

All systems OK on 2.1 (27) except the High School (IPO 412).

Symptom:

1) Calls made stn to stn go to voicemail
2) Calls transferred from stn to stn on INSIDE call go to voicemail
3) Calls transferred from OUTSIDE call from local stn to remote site in SCN go to voicemail
4) PROBLEM: Calls made from remote SCN stn OR OUTSIDE line (local to IPO 412 OR from the 406 @ Core, home of their DID/PRI) and TRANSFERRED from a local stn to another local stn disconnect or hang silently w/o going to voicemail.

EXCEPTION: If user DND is on, call goes to voicemail and yes, I tried shortening the allocated answer interval-no success.

Check the FastStart box on the ip trunks. Turn it off, we had a similar problem and that was the fix.

UPDATE: It is now been proven to occcur @ all sites except for the site (406) that is local to the VMPRO server. I cannot transfer remote-outside calls w/in a site and have VM coverage. The schools are letting out in a 1/2 hr and we'll change the settings and reboot.

We have an almost identical site further north and faststart is NOT turned on there. We had originally checked it in order to rectify a problem with outbound calls experiencing no audio and never reset it.

We'll let you know, drdialtone321. Thanks.

Disabled Faststart and it did not solve the problem. We had about 70% failure and it actually caused some calls to (ring)silently from the remote sites. We could connect but our end nver heard the ringing.

Tonight we are going to try pegging all the units and fiber tranceivers at 100/H per advice from AVAYA Tier IV.

I had same problem with similar set up with schools.

Make sure you have the following turned on the VOip lines at both ends

Enable faststart
Out Of Band DTMF
Allow Direct Media path
Voice networking.

Also make sure u correct number of VCM channels selected..

I'm having the same problem at a site. The customer is using all analog phones w/ Phone Manager Pro and has figured out if they do a blind transfer from PMPro, the call forwards but a regular transfer doesn't.

disable faststart

 

[jtierney]

When we disable faststart, from the remote nodes, we get silence on outbound calls over the PRI @ the core 406 unit(instead of audible ringing) until the call connects. Also, we still had a 50 -70% failure rate on the transfer issue.

AVAYA TIER III is suggesting the following steps (which we will be trying tonight.

1. Turn off "local tones" on both ends of VOIP line. All sets are 44xx or analog.
if that fails. .
2. Set codec to Auto (from G711, customer has 100mb fiber)
if that fails. . .
3. Upgrade from 2.1 V15 to 2.1 v27 (yesterday, we uploaded the full version of 2.1 V14 VMPRO over the patched version we were running. . .no change)

We'll let you know.

RESOLUTION:

Turned off "local tones" on the VOIP trunks and upgraded (VM working w/ very slight delay)

Next step tonight is to upgrade all IPO's to v27 (from v15)

Thanks everybody for the feedback.

How many VCM's are on the switch? Sounds like there's an IP to IP setup problem

 

[jtierney]

The upgrade to v27 has solved the problem.
