Why not use rfc2833 instead?

When I changed the Aastra phone settings to use SIP INFO, am not facing this issue. But, when I change it to use RTP for DTMF, then '#' is getting detected more times.
I did a pcap and listened to the audio, I could hear only one tone(beep) for each key pressed. Is there anything other configuration to get it working in RTP?

If you are using a sip phone, you are MUCH better off using non audio based dtmf like rfc-2833. If you are already using this, its possible that what is happening is the phone is sending the dtmf as audio and 2833, at which point, you should not have to use spandsp_start_dtmf at all. If the phone is sending only audio, and is not capable of using any other method, you will need to pull a pcap of this call, use wireshark to extract the audio, and do some analysis of the audio to figure out why it is detecting multiple digits.

Hi,
When I use spandsp_start_dtmf along with play_and_get_digits, '#' is getting detected many times, though it is pressed once.
Other DTMFs are getting detected properly, whereas the '#' is getting detected 2 or 3 times.
I have checked the SIP phone's settings, I do not find anything wrong there.
What could be the reason? Is this because of some SIP phone setting? Here is the freeswitch log,
