I've got a issue with call pickup for a bunch of SIP phones in South America. It's a small office of around 10 senior staff and 1 receptionist. The office is small enough that reception can hear the users phone ringing. The receptionist likes to answer the ringing phones with the 'Pickup' soft key on their 9951. This works well and everyone was happy; any phone can pickup any other phone.
The users started to report that they do not see the correct Caller-ID if they pickup someone elses phone..... While troubleshooting we see the original CLID shows up on screen of the dialed extensions handset. But when the 3rd phone answers the call the CLID appears ontheir screen as 'service-uri-pickup'.
It would appear that our CME is hairpinning the call and a debug of the ccsip messages shows two call legs. The first leg being between the calling part extention and the called party extention. The second leg is between the 3rd phone extension and 'service-uri-pickup' which I guess kinda makes sense as we force our CME to sit in the call path..... After a lot of searching and reading of the config guides I have not found a fix or workaround for this.
Does anyone know if it is possible to preserve or re-write the original CLID into the 2nd leg? It's kinda anoying that you can't see the CLID of who you are speaking to. It's a bigger issue if you wanted to call them back as the Call History just shows you had a call from 'service-uri-pickup'.......
