NO JOY Certain outgoing calls not connecting

[TriStarGod]

Hi Guys,
First question:
Certain outgoing calls like 866-783-7422 (a waste management company phone line) don't connect with our system. On our 3CX phone, it rings forever but never connects. The only pattern I recognized among the numbers that are affected by this issue is that the outgoing phone system instantly connects (no ringing) when called via cell phone. In fact, it immediately leads into the outgoing number's ivr. How would I fix such an issue?

Second question (less dire):
The free 3CX phone can have up to 5 active lines. Is it possible for incoming calls in queue to take an available line while another call is ongoing like on those old phones with multiple blinking lights (each light representing a call in queue)?

Try adding
progressinband=yes

To the sip settings.

Hi atsak,
I went to Asterisk SIP Settings and added progressinband=yes at the bottom. Unfortunately, it did not work. PIAF did mention that /etc/asterisk/sip_general_custom.conf may be overriding some settings so I even placed progressinband=yes in that conf file as well but that also didn't work.

Sounds like a carrier and routing issue. Who is your provider? In your own routes do all calls go to the same provider. The provider if you can get them on the phone can do a trace with you on the phone and see where the problem is. with Anveo Direct you get a SIP trace on every call and you can pick which carriers handle which calls.

briankelly63 I use an unlimited incoming/outgoing VOIP service provided by TelcoDepot. I thought the problem rested with them as well but their own system, which also use the same type of VOIP service as ours, don't have such an issue calling these types of numbers.

The processing of calls by your provider may be influenced by the caller-id number you have assigned to your outgoing trunk. If your provider allows you to change your outgoing CID try several different area codes and numbers and then place the calls.

Hi briankelly63
I changed the outgoing number in my trunk but it had no effect. However, during my VOIP service setup, I did request the CID to be set on my provider's end. I will call and ask them to change it to see if it fixes the problem.

They may not want to do that but if you explain your testing a theory I'm sure they'll give it a try.
