Voip (sip)

We have an asterisk installation onsite, and our arrangement with the voip provider requires us to receive a call, then immediately forward the call to another company that hosts our crm dialer. This has introduced latency that is unacceptable for the call. I need an expert to help me eliminate the latency by tweaking asterisk or making other technical suggestions.

Voip

I have been facing many problems with our voipswitch configuration ever since we tried to implement the black list feature via the voip switch. I removed the blacklist feature since we saw that it caused us more problems than we anticipated.. the issues we are facing now : 1.) asr : our asr before the black list installation would reach 35% with clients. Now it is reaching 15% . The main reason we are getting for dropping the call is cancel ( sometimes when we test we do not hear a ring tone and get dead air or pdd) this is a reason why we feel the callers end the call before it is connected.. 2.) acd : our acd also has decreased from 7 mins to 2 mins . 3.) we are getting different cdr's with our clients always 4.) we want to confirm that we are giving our client a proper 503 , so if the call is dropped /rejected from our route the call returns to them. We are advised by our client that most of our issues will bee resolved by the codecs or sip configurations.. . Thank you .

The Session Initiation Protocol (SIP) is a signalling protocol, widely used for setting up and tearing down multimedia communication sessions such as voice and video calls over the Internet. Other feasible application examples include video conferencing, streaming multimedia distribution, instant messaging, presence information and online games. The protocol can be used for creating, modifying and terminating two-party (unicast) or multiparty (multicast) sessions consisting of one or several media streams. The modification can involve changing addresses or ports, inviting more participants, adding or deleting media streams, etc. The SIP protocol is situated at the session layer in the OSI model, and at the application layer in the TCP/IP model. SIP is designed to be independent of the underlying transport layer; it can run on TCP, UDP, or SCTP. SIP has the following characteristics: * Transport-independent, because SIP can be used with UDP, TCP, SCTP, etc. * Text-based, allowing for humans to read and analyze SIP messages.
