Hi,

My name is shaik abdullah, i have a problem over SIP TRUNK to PSTN, Incomming and Outgoing calls working fine. but when i call from

cisco IP phone to PSTN any number it is connected and RTP established, but if the distanation is having IVR with extensions, When user dial that

extension the digit is not passing to PSTN.

We trace with Telco they did recieve any digit after call connected. Please advise if any mistake in configuration below.

Current call manager version is 5.X and voice gateway using 2811.

We trace with Telco they did recieve any digit after call connected. Please advise if any mistake in configuration below.

You mentioned about a destination with IVR & Extensions, does that fall under your control ? If yes, then look for why the DTMF digits are not being detected by that destination system. As you mentioned, even your Telco sees the DTMF digits passing through after the calls are established.

If the destination system doesnt fall under your control, may be then you should talk to them & ask them why your DTMF digits are not recognized by them. Is it happening only to your calls to them or happens with all the calls or random calls, they should troubleshoot on that part.

Pls rate the post if the info provided above helps.

Hi!

Did you enable Require MTP option on CallManager?

Look here, if you didn't allready, maybe can help:

http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a00808b6ca6.shtml#Tp2

I dont think MTP is an issue here, as he clearly mentioned that his Telco sees the DTMF digits coming in after the call is established. The issues is they are not recognized by the destination system, perhaps MTP is an issue there or DTMF recognition is disabled by mistake.
