Hi, I'm have Cisco IP Phone + Cisco Switch + Cisco Router + an SIP account release from ISP (internet service provider).
My topology: Cisco IP Phone => Switch => Router => ISP
But I can't calling from inbound to outbound and from outbound to inbound.
My Cisco IP Phone use SCCP firmware 8.3
Sometime, I repair something and I can call to outbound but when I Answer, the call will "hang out". And when I calling to outbound, I can "hang out" from my Cisco IP Phone, I was press "End call" but outbound still ringing, it's not "end call" (Have problem between SCCP firmware on my Cisco IP Phone with SIP account I register from ISP?)
Please let's me know what should I do? What's the port I need open??? How to complete this config??? I hope you can help me resolve that problem, thank you very much!
