[Asterisk-Users] CAS SF Inband tone signalling problem
Hi, I am having some problem in defining CAS SF Inband signalling on a Digium E100P card. The problem is that the syntax given in the sample zaptel.conf doesn't work. Can someone provide me with an example of the syntax. I am trying to connnect asterisk with another exchange using a E1 CAS. I guess SF is the only option as the rest fxo,fxs,em etc are all subscriber end signalling. i need a CO to CO (or PBX to PBX)signalling...Somebody guide me on that too. Any help will be highly appreciated.

RE: [Asterisk-Users] CAS SF Inband tone signalling problem
EM is the traditional protocol to connect two COs or PBXs together. EM trunks are inherently symmetrical. So there is no subscriber or CO side. You have to see about the higher level signalling protocol to make sure dialed digits etc work right. Regards. Alfred R.

Re: [Asterisk-Users] CAS SF Inband tone signalling problem
Channel Associated Signaling is a simple 4 bits 'protocol' often used in digital non-isdn E1 connections to define/indicate the state of the line (or channel): sieze, sieze ack, idle, etc, at a given moment. Usualy, only 2 of those 4 bits are used. However, given that CAS tables may vary from manufacturer to manufacturer, the most important thing to start with in a PBX-to-PBXCAS connection is to identify the CAS table being usedat the far-end switch. If you can not easily obtain the tables on the far-end --which is the usually the case whenthe brand of your switch is not the sameas the one at the far end, or if you don't have previous experience with CAS, you may get stuck even if you have a CAS analyzer. Given that in PBX-to-PBX scenarios you usually go with EM signaling, you will also have to deal with the start arrangement; usually WiNK or IMMediate You have to have the same start arrangemnet for each direction (REC/XMT) as the far end switch. If Wink Start, you also have to deal with the length of the wink pulse. If you have the far end CAS table, just program yours to match their values. I am new with Asterisk and have never used zaptel.conf, but if u attach the far end CAS table to your post, we can be more precise in helping.
