Okay, so a little late to the party on this one… The other day I had to setup a TDM (E1) based SS7 link (oh yes my friend – they still exist) to interconnect with another operator. I’m using Cisco’s ITP product as the STP / Signaling Gateway, and my trusty port mirror for what’s […]

In our last few posts we got CGrateS setup in order to have rates and tariffs in the system, so we can price a call. Where we ended we were able to use the APIerSv1.GetCost method to get the cost of a call, and today, we’re going to actually create some rated CDRs. So again […]

Recently I had a strange issue I thought I’d share. Using Kamailio as an Interrogating-CSCF, Kamailio was getting the S-CSCF details from the User-Authorization-Answer’s “Server-Name” (602) AVP. The value was set to: sip:scscf.mnc001.mcc001.3gppnetwork.org:5060 But the I-CSCF was only looking up A-Records for scscf.mnc001.mcc001.3gppnetwork.org, not using DNS-SRV. The problem? The Server-Name I had configured as a […]
If you’ve ever received an SMS from your operator, and the sender was the Operator name for example, you may be left wondering how it’s done. In IMS you’d think this could be quite simple – You’d set the From header to be the name rather than the MSISDN, but for most SMSoIP deployments, the […]
