I do not know if Sahil has a legacy PBX but you have....this is really
interesting because I do have an old legacy PBX connected to Asterisk
(via PRI trunk) which is connected to PRI telco.
The problem arises when I call from an analog phone connected to the
legacy PBX passing thru Asterisk to the telco.
In other words if I call number 12345 from legacy PBX I receive the
"Channel 0/5, span 1 got hangup request" but it works if I use a SIP
phone connected to Asterisk PBX. I think the secret is in zapata.conf
configuration..infact I changed some values and magically I could make
outbound calls!!! The only drawback was I couldnt' receive any inbound
Do you have the same problem? If yes have you tried to call those bad
numbers from legacy phones and from SIP/IAX?
