Hi Cisco Community Support,
We have an issue where internally forwarded calls to external are not receiving RTP, this was rectified by using the following commands:
voice service voip
However, even after having saved the configuration the command appears to disable itself after a reboot and has to be re-applied.
The device is a 2901.
The IOS version is: 151-4-M4
Can anyone confirm as I have looked through the documentation on this but have failed to find anywhere that explicitly defines that this command is dropped upon reboot.
Any help will be greatly appreciated.
