Hi y’all. I have a question. Do you know what could hang-ups like dropped calls on cell phone? I did a test call to 1-777-123-4567 and I am able to use the service long enough that I thought I could confirm that the one who’s causing hang-ups isn’t me. I can still keep going after 5 minutes.
For example, I placed a call to my mom’s cell phone to leave a voicemail in case my mom did not answer her cell phone. While in midst of leaving her a voicemail, I got hung up for no reason.
My mom uses Verizon and she’s in Altha, FL, which is west of Tallahassee and east of Pensacola, FL. Altha is a rural town. I’m in Orlando, FL. My calls did not drop when my mom called me about a couple of times. I checked the coverage for Altha, FL, but they all show red, which led me to believe my mom does get signal in her cell phone. She’s with Alltel before the acquisition.
My softphone that I use is X-Lite 3.0.
I am running Asterisk 1.4.28 in Ubuntu 9.10 Karmic Koala.
Here’s my outgoing (no incoming) settings for CallCentric (note that I patched G.722 in Asterisk 1.4.28):
context=from-pstn
host=callcentric.com
fromdomain=callcentric.com
username=1777MYCCID
fromuser=1777MYCCID
defaultuser=1777MYCCID
secret=****
type=peer
insecure=port,invite
allow=ulaw&g722
disallow=all
My register string is in a format of 1777MYCCID:Password@callcentric.com/1777MYCCID
Here’s what I have in /etc/asterisk/sip_custom.conf:
context=from-pstn
srvlookup=yes
session-timers=refuse
session-expires=180
session-minse=90
session-refresher=uas
Is there anything I can do in my end to prevent dropped calls? In short, for outgoing calls I make to my mom’s cell phone, everytime my mom answers the phone or Verizon’s voicemail takes over for her to leave a voicemail, after about 30 seconds, my call drops. Incoming calls doesn’t seem to be affected, since I’m able to talk longer in the phone. My call did not drop if I dial a 1-777 number, like 1-777-123-4567, which connects me to the “Tell Me” service.
I think it may be very tough for any Asterisk users to figure this out but I don’t know what to do. Could it have something to do with session-timers, session-expires, session-minse, and session-refresher as taken from the CallCentric’s support page? It’s in Asterisk/FreePBX.

Update: I clarified the subject about what could cause dropped calls. I will attempt to make a phone call to my family and show the output of what’s going on.
