One way voice issue

I have tried setting up a basic VoIP configuration between 2 branch sites using 2 service provider networks using Cisco 1750
routers.
One setup was over a frame relay network and the other over a PPTP tunnel link that goes through several intermediate
routers.
The setup worked fine on the frame relay n/w. Over the PPTP link however,the calling party doesn't get the ringback although
the phone at the other end rings. When the called party answers, he can hear the calling party but the latter doesn't receive
the voice stream. This was always the case.
With some debugging I found that the called party sends the RTP voice stream to the wrong RTP port at the calling party. The
port nos were always 2 greater than the correct one.
Eg:- called party sends the voice stream to 18002 when the calling party's end shows that its RTP port should actually be
18000. There was no port mismatch the other way.
Has anyone faced this problem?

VoIP Setup

We are working on VoIP Project and providing VoIP services for our customers.The following is the description of my project.
In this project, each customer can be assigned an account number and a Personal Identification Number (PIN), they can get
these information from scratch card, which are available on our customers outlets. The user dials a local number like 111-
XXX-YYY, and is connected to the local VoIP point of presence.
The user is then prompted by the Integrated Voice Response (IVR) to input the account and PIN numbers, and following an
authentication, after the proper authentication, a second dial tone allows the user to enter the target number. The user
dials destination phone number, which the local Voice Gateway maps to an IP address of a remote-zone Voice Gateway.
The remote-zone Voice Gateway then selects a gateway to terminate the call. This completes the call set up. During the call
setup the accounting is going on Database Server through AAA Radius and calculate the time duration and total minute use by
the caller and after termination of the call, billing automatically update user accounts with current statistics.
I need help on this project regarding equipment selection and their configuration.Can any one share his/her experience with
me.
Thanks for your cooperation.

The longer than expected post-dial delay could be incurred by the interdigit timeout due to the command destination-pattern
37T. The "T" option instructs VoIP GW to wait for 10 seconds before completing digit collection. Try destination-pattern
37....(actual number of dots depends on the number of digits in the number)to remove interdigit timeout
