Transfer to external system not working.

[MarkSitzler]

Hi all,
I am currently having issues with my phone system setup. Setup is like, two client location and both hosted separately. I am trying to achieve call transfer from location A to location B during break hours, but when I am prompted the IVR of location B, I am not able to input anything it asks press 1 for reception and 2 for sales, but it doesn't accept any input.

Check codecs, packet trace, and talk with the trunk providers - on both sides. It looks like your DTMFs are been whisked away somewhere along the path.
