[asterisk-users] A Strange doubt and problem

[Crazy Boy]

Hi Friends,

I got a strange doubt and problem. Is there any problem for SIP protocol, if we configure Intercom (SIP), VoIP (SIP) and PSTN in a single server (that may be Asterisk or Trixbox).

My First Experience:

Initially I configured  Asterisk in a system and created SIP extensions and VoIP with Teliax. It worked very fine for a few days. After that, I configured PSTN (Digium 04B and 20B) and making outgoing and receive incoming calls. After that, SIP protocol was down and unable to make calls to USA using Teliax using SIP. So, I configured IAX2 Teliax account and its working fine now. Why SIP protocol was down?

My Second Experience:

I have installed Trixbox ISO image in a system and configured as mentioned above. Now, I have faced the same problem. After configuring PSTN only, SIP protocol was dead. What may be the reason?

Error Message: 

When I am making call to USA using Teliax service, it is telling that "All circutis are busy. Please try call later. Thank you".

Please share your feelings and experiences. Looking forward to your response. Thank you.


Regards,
Chandra.
