Asterisk works as the converter between SIP and H.323. SIP - internal network, H.323 - VoIP telco.
Context responsible for switching:
[voip-sip]
exten => _.,1,Dial(OH323/9999#${EXTEN}@80.237.12.33|60)
exten => _.,1,Hangup
exten => _.,2,Hangup
Sense of record - on any number we call through OH323 using number with prefix 9999#.
80.237.12.33 - ip address of Telco softswitch. Timeout - 60 seconds
Addition before number 9999# is requirement of the Telco.
We call for example on 74957852525. The call passes successfully.
