With the increasing improvement of VOIP technology, IP phones are no longer in the water or in the mirror. People who do not operate on computers can also use China Telecom, China Unicom or JiTong's IP phone cards to send low-cost communications to friends and relatives on the other side of the ocean. The "chicken" family is also making full use of the high-tech means of Internet connection, using a variety of software to contact friends. Network telephone sof

Implementation difficulty: H.323 signaling information conforms to asn.1per binary encoding and requires special codecs. SIP information is text-based and is coded in UTF-8 using iso000046. Text-based encoding can be easily implemented in Java, TCL, Perl, and other languages for convenient debugging.

Assume that there is a mailmanager class that is responsible for receiving emails. The mailmanager class exposes a newmail event. When a new email is received, the newmail event is triggered, cause the mail to be delivered to the mail processing object (fax and pager objects ).

than just plain. It is clear to give an example, and there is already a very good example, that is, the "All-in-One Machine" in the SRP principle ".
In the "All-in-One Machine" example, although the "All-in-One Machine" has the "print, copy, scan, and fax" function at the same time, we do not design an "all-in-one machine" interface, instead, four interfaces are designed. In this way, the class that calls an interface can precisely use an interface
Business Challenge: Create a more reliable and efficient way to receive and process trade confirmations at home and abroad.
Solution set: NEON Access IBM MQSeries, s.w.i.f.t. interface.
Results: Neon canceled the slow, inefficient manual way of receiving data from faxes and telegrams, and replaced it with a very stable solution that would greatly shorten the time needed to process s.w.i.f.t (Global Interbank Communications Association) messages.

Second, if the administrator uses a 64-bit operating system platform, there is a special requirement when deploying the audio decoder. That is, if Microsoft audio codecs are selected, the Windows Media Encoder must be installed. This is a problem encountered during the platform's excessive stages and cannot be overcome for the time being.
