Case Studies For Cisco CME Implementations Using SIP

[exonetinf1nity]

Greetings, our primary customer base is located in the UK, we have been deploying a number of voice products from Cisco from CME through to Call Manager, until recently we have relied on technologies such as dedicated leased lines and isdn for voip connectivity.

We have been using SIP for quite awhile but never looked at deploying it using DSL technologies such as ADSL and SDSL mainly due to the fact that most ISP's dont support QoS in an upstream or downstream direction.

Could i ask if anyone here has had success deploying SIP with CME over the above DSL technologies and what challenges if any you have faced as we find it increasingly difficult to get smaller customers to adopt more expensive connectivity options.

Regards

SIP is an ASCII based, application-layer control protocol that can be used to establish, maintain, and terminate calls between two or more endpoints. SIP has rapidly emerged as the standard protocol used in IP communications, because it is a multimedia protocol that can be used for video sessions and instant messaging in addition to voice. Also, SIP can handle conference sessions and broadcasts, as well as one-to-one sessions.
