Sometimes when you are with a client on the telephone and it is going on too long, you need to be able to end the conversation without being rude or abrupt.  Here are a few ways to end the conversation:

a-Please accept my apologies, but I have got to go to a meeting.

b-I have just been called to a meeting so I will need to go, but we will talk soon.

c-It has been nice talking to you and I will get back to you in the next couple of days with the answers to your questions.

d-I am going to have to go now, but I will email you tomorrow.

All of these expressions help both parties to save face and to maintain a harmonious relationship.
